    Do components have an expiration date?

    According to my April 2011 issue of MBA "Mountain Bike Action Magazine" they do.

    Say you bought a bike in April of 2011 then you would need to replace the......

    Seatpost: Al- 2 years
    CF- 1 year
    Adjustable Height- 90 day rebuild

    Derailleur Cables: 6 months

    Rear Derailleur Loop: 6 months

    Saddle: 4 years

    Pivot Bearings- 1 year

    Front Derailleur: 2 years

    Chain: 4 months

    Rear Shock: 1 year

    Cranks: 2 years

    Pedals: 2 years

    Frame: Al- 4 years
    Ti- 5 years
    Steel- 7 years
    CF- 3 years

    Stem: 1 year

    Brakes: As soon as pads wear past mf's limit (durrr)

    Bars: Al- 1.5 years
    CF- 1 year

    Grips: As needed

    Headset: 1 year

    Brake Cables: 6 months

    Fork: 2 years

    Wheels: 2 years

    Tires: 6 months

    Of course it goes on to say this is an estimate based on you riding 10 hours per week year round and where and how hard you ride but you get the picture. What are your thoughts? What are some of your longest lasting components and how did you maintain them? Since pictures are worth a thousand words can those of you who have exceptionally long lasting components please share them?

    if you take a whiff of your rear derailleur, or other abused components and it smells like rotting fish than you need some new components, if you have any questions on expired products call the FDA and they should tell you if your bike is safe or not.

    10 hours actual ride time a week year round is really much more than 90% of riders put in. That's close to 100 trail miles a week, 5000 miles a year. I used to ride near that much, except less during winter months.

    Even doing major miles per year, many items in that list seem to be very short lived... unless crash damaged or not maintained.

    I didn't buy the ragazine so I guess my components may go longer.

    Yea.... I don't entirely plan on time-traveling to the future to buy bike parts just yet. Besides, the flux capacitor's been going wonky lately. I think it's been the weather.

    Good Lord! Is that really what they recommend?
    Fix it when it needs fixin. Or when you have the cash to upgrade for fun.
    I have to admit though. When it comes to aluminum bars, I like to replace them in about three years.
    I've got a seatpost that's going on 5 years and two bikes... in rough desert terrain. Plus I'm 200lbs.
    Carbon has no fatigue life, so as long as it's not damaged, it in theory has a much longer life than aluminum. That's what they've been learning with composite aircraft.
    That schedule doesn't seem to take into account the type of terrain being ridden either.

    I just thought of something. High Torque must be trying to sabotage the biking industry, so people will get back into their cars.

    Bearings and such should be inspected and lubed once a year. Most chains are stretched enough that they need replaced 2x a year, but most people just don't notice. shocks and forks should follow manufacturers service schedules. Which is usually oil and seals a few times a year and a major rebuild yearly.
    Static components have a fatigue life, that can depend a lot upon your riding environment and storage conditions.


    Some of the recommendations are odd, so look at the date of the magazine...

    Yeah, I kinda figured that article and the downhill bike for "closed course" labeling was an April Fools thing.

    10hrs/wk actual trail ride time...remember folks...people tend to say what they think "sounds" right, and exaggerate a bit...(I'm sure there are some that ride that much though.)

    The person to ask about how long parts last would be Craig Bierly...you know, the guy mountain biking all over the US.

    Bearings/pivot points should be checked periodically throughout the year. When I had my FS Kona, I checked the pivot points 3-4 times a year. Cleaning/lubing the pivot points would be done when the frame started creaking a lot. Once the pivot points were clean and free of dirt, I'd check the bearings for play/smoothness. This was done once a year, no more than 2 times a year.

    Since I'm no longer riding the bike and selling the frame, I thought I would replace the pivot bearings/hardware. So I disassembled the entire bike - pull the shock, rear triangle, etc - and checked them. Still smooth. So I just re-greased them up and reassembled the frame.

    Cables get replaced every year. Since I race XC for the M.A.S.S. series, I can't have any type of mechanical issues.

    Everything else I say meh.

    Seatpost: Al- 2 years
    CF- 1 year

    Adjustable Height- 90 day rebuild

    Derailleur Cables: 6 months - Depends on riding conditions

    Rear Derailleur Loop: 6 months Depends on riding conditions

    Saddle: 4 years I can see this being legit

    Pivot Bearings- 1 year If you check/clean periodically, no issues

    Front Derailleur: 2 years If it ain't broke, don't fix it

    Chain: 4 months Chain wear varies from rider/location/riding
    style


    Rear Shock: 1 year No need to replace, just have it serviced

    Cranks: 2 years Again wear varies from rider/location/riding

    Pedals: 2 years This is possible, pedals take a lot of abuse

    Frame: Al- 4 years Maybe, depending on riding style/conditions
    Ti- 5 years
    Steel- 7 years
    CF- 3 years I personally don't think that CF has a place in MTB, JMHO

    Stem: 1 year meh, unless your crash prone/heavy jumper

    Brakes: As soon as pads wear past mf's limit (durrr) Yeah, durrr

    Bars: Al- 1.5 years Same as stem

    CF- 1 year I'd go a little longer, going on 3 years on a set of Easton Monkeylites, but I don't jump/stunt/etc.

    Grips: As needed Another durrrr

    Headset: 1 year Keep it properly adjusted/serviced and it will last longer

    Brake Cables: 6 months Again depending on riding conditions

    Fork: 2 yearsKeep it serviced religiously and it will last longer

    Wheels: 2 years meh

    Tires: 6 months Depends on how many miles you ride, not time

    Hmmm. I have three bikes right now. If I went by these recommendations I would be left with one frame and a few components. Everything else would get thrown out.
    Throwing out MBA sounds like a better idea.

    Sounds like the 'Bike Manufacture and Repairmen Consortium' wrote the article and submitted it.

    I have an 84' Fisher that I have put thousands (?) of miles on. As far as I can remember, the only parts that have been replaced due to ware are the derauliers and tires. I have replaced the rims due to damage (used old hubs). Point being - every thing else is still stock - brake and derailleur cables, hubs, seat post, etc.

    If you maintain the bearings – bottom bracket, hubs, etc. - on a regular basis they will last a life time. I have to admit the hubs are little gritty when you spin them but they still work fine.

    Sounds like junk to me….

    Have you seen the expiration date on table salt now.
    2yrs.
    It’s been in the salt mine for 10 million years but it will go bad in the jar?

    What is this world coming too?

    They need to convince the readers to replace more stuff.....makes the advertising worth it for the companies that have ads in the magazine.

    lol at that list. I ride it till it truly needs replacement.

    WTF?!?!?!?!?!? Don't these guys do periodic maintenance and lubriaction to moving parts? All of my stuff has lasted much longer than their suggestions, and I'm pretty tough on my gear.

    I am a little worried about the jar of Mayonaise in the back of the fridge........ can't seem to find MBA's recommended replacement timeline for it.......

    Now you know why the rag is lovingly referred to as 'Mountain Bike Fiction'. When you can't figure out what to write, just make something up.

    I didn't read the *story* but perhaps someone who did can confirm or correct.

    Perhaps it was written more from a law of averages point of view rather than "it's worn out so scrap it."

    We all replace components of some form over the life of a bike (like more durrr).

    You buy a 2011 bike and due to breakage, general upgraditus, a breakthrough in shifters comes out in 2013, that Float R shock just doesn't have enough tuning capability for your improving technique at the end of the summer, you want to shave a couple pounds in wheels and tires sometime in 2012, a 33" bar is all the rage next Spring, 10mm more front travel in would be oh so nice for that Moab trip in 2014, and so on.

    Playing the law of averages, with millions of bikers riding offroad and even more bikes out there, stuff get changed. Some more durrrrrrrrrrr.

    Of course, tires, chains, cassettes, grips, chain rings, and other short term wear parts might need to be changed a few times a year depending on mileage, not the calendar. Durrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrr

    Obviously, mountain bike magazines make money from advertising mountain bike component manufacturers. Mountain bike magazines want to keep their advertisers happy. Apparently, normal wear-and-tear and upgradeditis don't generate enough sales by themeselves so help out your best customers by cranking out an article now and then suggesting you're riding a potentially-lethal carton of milk down the mountain if you don't get those about-to-expire parts replaced pdq.

    Oh, and conveniently, an ad for the part you're told needs immediate replacing is within a few pages of the article.

    8 speed XT crankset - 12 years, outer chainring's original, middle & inner replaced a few times
    Manitou X-Vert Super fork - 11 years, good as new
    XTR rear derrailleur - 13 years
    Wheelset's about 8 years, probably have a couple more before the back rim wears out

    Buy good stuff, take good care of it and it'll last a heck of a long time. The odo on my bike computer's rolled over a couple times so it's not like my bike's been sitting in storage, it's out there getting ridden every week.

    Not new, they've run the same story in the past. Bunk then as it is now.
    Say you bought a bike in April of 2011 then you would need to replace the......

    Seatpost: Al- 2 years
    CF- 1 year
    Adjustable Height- 90 day rebuild

    If I was running the absolute lightest, then maybe I'd worry about fatigue. All of the seatposts I've got are all older than that.


    Derailleur Cables: 6 months

    Replace when shifting starts to suffer.

    Rear Derailleur Loop: 6 months

    See above, or when fraying.

    Saddle: 4 years

    When torn, or for whatever reason no longer comfortable. I might replace some sooner than four years.

    Pivot Bearings- 1 year

    Inspect before replace, and it'll depend on who made the bike. Something like a Turner, probably will get a bit more than that.

    Front Derailleur: 2 years

    Nope. When it starts to act up.

    Chain: 4 months

    When it starts to show wear, buy a chain checker or measure the thing.

    Rear Shock: 1 year

    REALLY?!?! Replace a $300+ part once a year? Inspect, rebuild as necessary, replace when I want.

    Cranks: 2 years

    Same stuff. Inspect. Replace rings first, only replace when it is toast.

    Pedals: 2 years

    Because XTR and Eggbeaters are the same. Replace as necessary, not before. Think I'll replace cleats a few times before the pedals.


    Frame: Al- 4 years
    Ti- 5 years
    Steel- 7 years
    CF- 3 years

    They've just discovered that steel frames can get tired? If the frame is in good shape, why would I replace a Ti/Steel or even CF frame? Aluminum - if it is a lightweight racing frame, there may be some merit to it, maybe.

    Stem: 1 year

    Because these always fail without any indication at 12 months and 1 day.

    Brakes: As soon as pads wear past mf's limit (durrr)

    Bars: Al- 1.5 years
    CF- 1 year

    Inspect, inspect, inspect. If I'm running a 80g bar, yeah, it has a lifespan. If the bar is 300g+, it should last a little longer.
    Grips: As needed

    Headset: 1 year

    This should be news to HS that have warranties that are much longer than that.

    Brake Cables: 6 months

    As needed.

    Fork: 2 years

    Rebuild it first. A newer fork probably will work better, but what about the A-C measurement you can't find anymore. Or that the new fork now weighs a pound more. Not always a good idea.

    Wheels: 2 years

    Where there any ads by wheelbuilders/Easton/DT Swiss prominent in the magazine this month?

    Tires: 6 months

    Again as needed.

    Of course it goes on to say this is an estimate based on you riding 10 hours per week year round and where and how hard you ride but you get the picture. What are your thoughts? What are some of your longest lasting components and how did you maintain them? Since pictures are worth a thousand words can those of you who have exceptionally long lasting components please share them?
    Some parts are wear items - tires, tubes, cables, brake pads and chains. They are expected to be replaced as needed. But their schedule looks to be assuming that I beat upon my bike every ride, and don't maintain it. If we all had to use that schedule - we would have drained our trust funds by now.

    MBA is in the business of advertising. The stories are just longer, and nicer ads. The advertising sales probably account for nearly as much as subscriptions and newstand sales.

    They rant about online sites like this - hmm wonder why? Because there is a diversity of opinion where the reader has to think? Because I won't recommended the latest tested bikes or part to solve your dilemma when fixing the old one will do for a lot less $$?

    Yeah, in the March 2011 issue, in the article about choosing the right bike, there were 10 tips. Two of them were:

    "Read our tests" and "Don't read blogs"

    In order words:

    "Buy from our biggest advertisers" and "Don't listen to objective opinions"

    It's Mountain Bike Action...

    Assuming proper maintenance and discounting crash damage, I expect any component to last at least 5+ years. Consumable parts (bearings, seals, chains, jockey wheels) replaced as and when.

    For steel or Ti parts I expect the lifespan to be longer than me, my road bike is steel and from some time in the 1970s. It's ten-ish years older than me and still going strong. Everything but the rims, brake pads and consumable are original and it's probably covered 100'000 miles plus in it's life.

    Having said that, in two years of riding a fork would be stripped down 3-4 times and have the wiper seals replaced with the oil changed a bit more often than that.

    Some of that is just funny...

    I came from BMX and granted they were bricks and short, but the only part left standing after years of seriously ridiculous bike molesting abuse was your stem. One year?

    No kidding. I worked as a bike mechanic for 5 years and I've only seen 2 broken stems in all that time. One was an ancient steel stem on a bike that the owner must've left in a pile of slush & salt and the other was on a roof rack mounted bike where the owner had a brainfart and drove under a low bridge at highway speeds. Actually there was a 3rd guy who used an air ratchet to tighten the bolts on his stem and stripped all the threads in the process.

    BS, no doubt.

    Let's see, I ride a 2003 Stumpjumper FSR and I have a few original parts on it.

    Of course, the frame - it's about 8yrs old now.
    Front and rear derailleurs
    shifters
    fork and rear shock - but both have been serviced to keep them functioning like new

    Of the parts I've replaced, the brakes are the oldest. I put Magura Julie disc brakes on it about halfway through 03. The pads aren't worn out, but I think I'll replace the pads and bleed the brakes this year just because.

    Everything else has only been replaced either because it was a wear item (chain, cassette, tires, cables, saddle) or because I felt like upgrading it (pedals, cranks, wheels, stem/hbar/grips, seatpost).

    I have replaced the pivot bearings a couple times on the frame, and it seems like they're about due for another replacement. however, since I don't trust my lbs with that job, I'll be buying the tools to press bearings myself and while I'm at it, I'll service my bb and hubs.

    I haven't read the whole article yet, but a quick glance definitely gave me a chuckle.... they are obviously pandering to their advertisers by trying to convince readers to spend money when they don't have to.

    I have a 2006 Specialized HR that came with not-top-shelf components.... while I do suffer from upgraditis at times, the wheelset, headset, and bb/cranks are all stock.... hub bearings (loose ball) were replaced.... otherwise, I just clean and grease once or twice a year.... derailleurs, shifters, and levers last forever as long as you don't smash them... handlebars and seatposts will only need to be replaced if they are severely fatigued.... and that generally doesn't happen from casual trail riding...

    The only wear items most riders need to worry about are tires, cables, and chains... and even those do not "expire". Everything else just needs to be maintained properly and inspected. Putting expiration dates is just an idiot-proof way to remind people to spend money when you don't do proper maintenance and inspections. MBA thinks their readers have no common sense.
    You better just go ahead and drop that seatpost down to the reflector... the trail gets pretty rough down there.

    I bought that issue, thinking that it might actually have some kind of useful, objective information. I must be optimistic.

    The last sentence in that "article" says it all: If you are a true mountain biking fanatic, chances are you will have moved on to new and improved equipment before coming close to our expiration dates. Nothing like implying that riders are poseurs if they don't buy new components every year or two.

    I also like how MBA tends to gloss over or omit information. In the same issue, the RM Altitude test omits "Descending" as a heading in their testing. I can only assume that the RM therefore is a shitty at going downhill.

    I'm giving up on that rag, and like others have mentioned, buying Cosmo.

    So according to this article, I should only need to spend about $2k per year on parts, and a new frame every couple years? Hum, I wonder who thrives on a budget made from advertising?

    Yeah but, this is what you spend anyway, a two biker family and all

    Well it wasn't such a crappy mag with RC at the helm. Just seems to have gone downhill in the last few years. If it was me I would have promoted Zap to be editor instead of Jimmie Mac.

    Derailleur Cables: 6 months

    Headset: 1 year

    Brake Cables: 6 months

    Fork: 2 years

    Wheels: 2 years

    Tires: 6 months

    Of course it goes on to say this is an estimate based on you riding 10 hours per week year round and where and how hard you ride but you get the picture. What are your thoughts? What are some of your longest lasting components and how did you maintain them? Since pictures are worth a thousand words can those of you who have exceptionally long lasting components please share them?
    Is this for real? Did they really say all that? What do these people do? Dunk their bikes in saltwater after each ride and leave it out in the snow all winter?

    Yet another reason why I don't ever read that awful excuse for a mt bike mag, other then for the train-wreck entertainment value. What utter crap. I am not even going to bother answering any of it. Just forget you ever read it, along with anything else those clueless idiots print.

    I'm glad you posted that info, I had no idea my bikes were so expired but they're all going straight in the trash before I get salmonella or even botulism from riding them.

    I couldn't afford to ride if I followed their replacement schedule, or I'd have to go with the lowest end, last year's bargin bin sale items. What fun would that be?

    I hope its components have a longer shelf life.

    MBA is out of touch with the average mountain biker. Seriously, how many of us here have plunked down 4K + for one bike (let alone 10K ) ? We may spend that much, but it will be on upgrades, and that'll be over the course of years.

    i remember when i thought 300 bucks bought a nice bike and when i got the "bug" and started riding my little trek 3500 i soon found out that bikes were waaayyyyy more expensive then i thought. I started getting magazines like mba and they had these bikes that were $5000 and couldnt believe it. I thought it was a type O. Then i started riding regularly and fell in love with it and to be honest if i had the money to buy a $5000 to spare i would drop it on my dream bike in a heartbeat. I look at it as a investment in my heatlth and happiness now rather then just a bicycle.

    You guys are forgetting its not about agw, its about how many riding hours.
    They do it based on 10 hours a week.

    4 month = 160 hours. I can agree on replacing a chain after 160 hours. Totally reasonable.
    6 month = 240 hours. Do you get 240 hours from your tires? I don't get half of that on the rear.

    Forget about months and weeks. Open your strava and see how many hours you rode. That will put things in perspective.

    For the record my city bike is a 15 years old steel mountain bike. Everything original. The thing is that it does not get ridden a lot, never on trail and spent most of its life in a garage. So yeh 15 years, but that's not what they are talking about.

    Interesting topic. MBA's definitely skewed toward frame and component manufacturers. My personal experience is a little different -

    Frame:
    Ti- 5 years - my 1996 Litespeed Hiwassee is still going strong with 5K+ miles registering on the cycle computer (95% of that off road). A couple of times a year I throw it up on the bike stand and check it for stress cracks. Until I see (or hear) anything suspect I'll keep riding it.
    Steel- 7 years - my buddy's Independent Fabrications steel frame has been beaten on, ridden hard, and it still rides like the day he bought it 14 years ago.

    Seatpost: Al- 2 years - I'm still using one of the first Thomson Elite seatposts produced. Like my frame every so often I pull it out, put fresh grease on it, and inspect it for cracks.

    Derailleur Cables: 6 months - 14 year old Gore Rideon cables still shift smoothly and only need a once a season adjustment.

    Rear Derailleur Loop: 6 months - 15 year old Shimano XTR still going strong with 5K+ miles on it.

    Saddle: 4 years - I just bought a new WTB Rocket V saddle to replace my 15 year old WTB SST K saddle (it didn't need to be replaced due to wear, I'm just looking for more comfort)

    Front Derailleur: 2 years - 15 year old Shimano XT still shifts like butter after it's annual adjustment.

    Chain: 4 months - once a season for me.

    Cranks: 2 years - 12 year Race Face Turbines. Getting a little nervous about my ability to find replacement 8 speed chainrings.

    Pedals: 2 years - 14 year old WTB Stealth pedals. Still work like new after an annual service and some new old stock cleats found on Ebay.

    Stem: 1 year - every few seasons I replace mine on principle.

    Brakes: As soon as pads wear past mf's limit - I'm stone aged I'm still using Avid rim brakes. Pads get worn I replace them.

    Bars: Al- 1.5 years - another item I replace every few seasons out of principle.
    CF- 1 year - for about five years I had a Easton EA 90 bar. On one of my inspections it showed some deep gouges from the stem, brake levers, and bar ends. Switched back to aluminum after that.

    Grips: As needed

    Headset: 1 year - 15 year Chris King with absolutely zero reason to ever replace it.

    Brake Cables: 6 months - 14 year Gore Rideon still work perfectly.

    Fork: 2 years - '99 Rock Shox Sid. Still holds air, stanchions are clean.

    Wheels: 2 years - 12 year old Bontrager Valiant/XTR wheel set. Until my brakes grind through the rim walls I'll keep riding them

    Tires: 6 months - I ride my tires until I notice them losing grip or start pinch flatting a lot. It ends up being every couple of seasons

    From my experience if you buy good components and take care of them they will last for significantly longer than MBA's timetable. Maybe not forever but easily 2-3X longer than their claims.

    If you are really putting that many hours on the components, MBAs figures are really not that far off. Chain in 4 mo? Absolutely. Pedals in 2 years? Yep, and on and on. The point is that these are wear-items for the most part. A few high end manufacturers or components buck the trend, but again, these are wear items. They aren't really meant to be used indefinitely on a bike, ESPECIALLY anything drivetrain-related.

    This thread made me LOLoud! And I never read past the OPs initial post. According to what the OP listed that the magazine said I have a block of cheese in my refrigerator that has outlasted most of those parts. It's all marketing hype to get clueless people to "buy" replace parts prematurely. More money flowing through the industry.

    That's not true at all. A lot of things listed have insanely long service lives precisely because the manufacturer doesn't want lawsuits


    Seatpost: Al- 2 years. Almost infinite
    CF- 1 year indeterminate

    Saddle: 4 years why?

    Front Derailleur: 2 years only if it doesn't work any more

    Cranks: 2 years not true

    Pedals: 2 years bearings can be lubed and adjusted

    Frame: Al- 4 years
    Ti- 5 years infinite
    Steel- 7 years infinite
    CF- 3 years

    Stem: 1 year who says?

    Brakes: As soon as pads wear past mf's limit (durrr)
    What......

    Headset: 1 year again why? relube or replace bearings

    Fork: 2 years you can buy bushings and seals you know.....

    Wheels: 2 years cant service bearings or freehub?

    Stuff lasts a very long time if you take care of it.

    I agree and I question the aluminum frame lasting 4 years. Why fatigue? Doe's aluminum get weaker as it ages? I have an Intense UZZI-SL that is an 01' frame but bought new in 02'. It is my only ride and it has been ridden on average 2 times a week 3 hours per ride for 11 years and still going.

    Alu does fatigue but it depends on how it's used not how long you have owned it. My alu mtb frame is 9yrs old and it hasn't fatigued yet. But I also don't beat the living snot out of it. But it will eventually crack and that is in my mind.

    I did just replace my 9yr old xtr rear derailleur because the pivots had too much play and it started throwing chains. As of now the only original stuff on the bike are the shocks, front derailleur, and brakes.

    Yeah stuff wears out but those mag recommendations assume that you are putting it through a LOT of heavy use which a lot of folks don't do.

    If you do all the power to you but you will be replacing stuff more often. Just the way it is.

    Where do they come up with a 4 year life span of an aluminum frame. I am 205 lbs and ride it pretty hard and jump it. I have cracked a couple frames prior to this. But from what I said above in the length of time used in 11 years of use I question their statement. Every frame is different thicknesses and different alloys along with use and weight of rider.

    Yup, they are all different. Just got to keep an eye on your stuff. Maintain what can be maintained and replace when necessary.

    Seatpost: Al- 2 years. Almost infinite
    Depends. Dissimilar metals can and have caused some problems, sometimes raising and lowering can start to score it some. It's good to be thinking about it in 2yrs time, but it may not require it. On the other hand, we've had to use some pretty extreme measures at the bike shop to remove seized posts...
    Saddle: 4 years why?
    I don't think I've ever had one last 4 years. The edges start to get torn away first, then either it starts to lose the integrity of the cushion, or the rails bend in a crash or impact. Possibly weakened by other crashes or impacts.
    Front Derailleur: 2 years only if it doesn't work any more
    Pivots wear, it gets sloppy etc. Mine currently doesn't really work all that well anymore, but at least I don't use it
    Cranks: 2 years not true
    Well, that depends. Shimano hollowtech? Ok, for the most part sure, but you may want to switch out the bearings to enduro-bearings after 2 years, which is cheap. Raceface/truvative's version of external BBs that still uses a taper-lock system? Take that on and off for two years (for cleaning, servicing suspension pivots, etc) and tell me it's still as solid as the day you bought it. In fact, my DH bike was suffering from this when I let it go. The cranks weren't "totaled", but they were "creaky" with a little play due to taking them on and off many times. Poor interface can do that, so it maybe depends here...
    Pedals: 2 years bearings can be lubed and adjusted
    True, and I find shimano bearings to last for just about forever, but on the bikes designed to take some hits, 2 years seems about right. I can usually make the better all-mountain/DH pedals last about this long until it's just not worth it to fix them (by replacing parts, cages, etc). It's about 2 years before they're just beat to hell bashing rocks and everything else. 2 years is infinitely better than the ~2 months I get on crank brother's pedals, haha, maybe they're shifting the normal distribution curve over to the left.
    Frame: Al- 4 years
    Ti- 5 years infinite
    Steel- 7 years infinite
    CF- 3 years
    Yes, this one is odd, some things to think about though, impacts, dents, gouges, and so on. Most of these happen within "normal use", but can significantly degrade the life of a bike. The numbers above might correspond to some of that. Not only that, but some full suspension bikes are designed so poorly that the bearings give out, ovalize the holes, and make the entire bike worthless. This takes a few years to happen usually, and replacing the bearings helps, but especially for older bikes, they just weren't designed to go more than a few years with the poor suspension/pivots that they had, even with changing them out.
    Stem: 1 year who says?
    For the most part I agree, except for some of the really skinny-light XC stems out there that twist and flex significantly. I never really trusted those, even when new. There are still some of those out there, especially on older bikes.
    Brakes: As soon as pads wear past mf's limit (durrr)
    What......
    Well, hopefully this is referring to changing the pads, although my avid BB7s lasted about 2 seasons before they were complete trash.
    Headset: 1 year again why? relube or replace bearings
    Yes, this one is odd. Headsets are not high stressed parts, not much reason to change it, unless it was like a $10 headset or something.
    Fork: 2 years you can buy bushings and seals you know.....
    Well, yes, but what about having to buy new dampers and other parts? My 1st generation Reba fell apart, it lasted into the 2nd season and by that time it wasn't worth it anymore. The older forks especially weren't really made to last more than a few seasons. Manitous, RSs, etc. Some of them have such poor lubrication systems that they are basically self-destructing as soon as you get them. The biggest exception are the old bombers with their oil bath system. Change out the gunky oil, slap new seals and bushings in, and you are usually good to go. Not really the rule though, more the exception. For some forks, when you are looking at ANYTHING else + bushings + oil changes + new seals + things like air spring seals, it gets expensive quickly, it might be better served by a newer fork, or at least a total tear down and rebuild (not where they just replace the oil, but where every seal, bushings, and wear parts are replaced). Lots of peolple worked the fox-crowns loose or creaky after a while, and those were expensive. Yes, there are some great exceptions, but I've got to say that the 2 year thing for forks isn't all that far off.
    Wheels: 2 years cant service bearings or freehub?
    With regular use, you are probably going to need at least a new freehub (no, you usually can't service the bearings inside of that), new bearings, possibly cones if it's a shimano, and if not you might run into the problem of the ever-increasing bearing receptacle, because of the forces worn bearings put on the races. I've never met a freehub I couldn't break, but the best for me has been DT, and about 2 years is my best. Then there's spoke tension, and everything else. If it's truly being ridden as advertised, 2 years is probably time to start thinking about the wheels. Every once and a while you're going to hit something and get an impact into the rim, eventually enough hits may have an effect. 2 years may not mean everything on the wheels is trashed, but I've had that happen before and chances are something needs to be addressed.
    Stuff lasts a very long time if you take care of it.

    Stuff lasts less when you ride more.

    Looking at those numbers, you would think the OP was talking about a Walmart bike. If he is then those numbers seem about right!

    Or just somebody that rides frequently, which is what the numbers work out to...

    Unless you DH or FR or w/e, why would you ever need to replace your seat post? Maybe if you leave it outside for like 10 years then it will be in bad shape, but for me, the seat post really doesn't see much action. I hate sitting and spinning. I guess I use my seat less because I use my legs as shocks cuz I have a hard tail.

    You would have to be riding really hard in some pretty crappy conditions to wear an AL frame out in 4 years.

    Damn I just went down to my basement to check my bikes and all was left was a pile of melted cheese down the floor with some mud dusting it.

    Screw you MBA, I can't afford to go buy 5 other bikes anymore. How will I go to school and hit the trails now ???

    What's the expiration date on their shitty ragazine ?

    Only problem is... Many riders who put down that much hours usually have more than one bike that they use over the week. Heck I have a few different ones and I'm not even close to 10 hours a week, though I'd love to be.

    Did they throw a bike down the stairway and then do again and again till every parts failed ? Then for each throw the part survive, they add 2 months of life to their expiration date ?

    Maybe if by "frequently" you mean a 20 mile ride every day of the year.
    15mm is a second-best solution to a problem that was already solved.

    No, they just had some 15 year old write the article like everything else in that worthless mag.

    Based on 10 hours a week. If you do the math, I think they are actually conservative on many estimates.
    Tire 6 months = 240 hours, usually over 1000KM. If you can get 240 hours from many of the high end tires you are probably not riding hard enough to justify such tire.

    Tires are one of the few things they are actually reasonable about. However, about half of that list (stem, seatpost, bars, FD, rear shock, cranks, pedals, headset, fork, wheels) is total nonsense.

    Even with cables, frames, and pivot bearings, what they are describing is the very shortest end of possible lifespan, most last much longer than what they state.

    I think the answer to the OPs question is: NO!
    Everything is replace as needed as in "don't fix it if it ain't broke."
    If you properly inspect everything and maintain it, then that rule works fine.

    Is that not obvious? Then the bike is not getting that many hours/week.

    As far as fatigue life goes, unless MBA is testing components to failure like the racing or aircraft industries their 'life span' figures are total guesses. We know they are not so it's just B.S.

    Of course if you are crashing a lot or taking your pedals off rocks or generally get big air you'll be replacing stuff more, although I don't really call that kind of abuse 'wearing out.'

    The old Marzocchis are reliable as Jayem said. Mine was NOS in 2006 and is still going strong. I'm guessing 700 hours by now.

    My 1996 Race Face turbines have been on 3 different rides since I bought them new. I have had to change the BB once, and the bearings a few times. They very likely have 2000+ hours on them.

    My Avocet o2 was used in '96 when I bought it. It was recovered/refoamed in 2007. It is still going strong. Conversely I've broken one Selle Italia SLR after one season.

    My spd 535s are 16 years old. Yes they are nearly toast, but they still spin fine. The engagement claws are pretty worn out.

    My 952 XTR rear d was NOS in '06. I have crashed it twice hard enough to bend the hanger. It has 700 hours on it. It still works flawlessly.

    Now that I have 3 bikes it takes a lot longer to wear stuff out.
