    Other than not having the bead hook, how is this better or whatever? Same width? Lighter? Stronger? And if stronger, how would one perceive this? I have two sets of the wide rims with the hooks and could not be happier particularly for the price.

    The bead hook may help keep high pressure tires from blowing off the rim but will not do much for MTB tires.

    From one of Derby's posts.

    "If inflating under 65 psi and using TR bead centering rims, then bead hooks are useless. We will probably see rims without bead hooks become the standard for mountain bikes in a few years, and tire bead design will follow.

    Having no bead hooks allows a wider inside rim width. And the rim edge can be thicker and more durable without adding more weight compared to a rim with bead hooks.
    "http://forums.mtbr.com/wheels-tires/bead-hook-less-rims-they-future-836810.html

    For years I ran a heavy (675g) 36mm rim on my 26" AM bike and really noticed the added sidewall support to the tire from the wider rim over my 24mm XC wheels, especially when running lower pressure on bigger tires. I am sure the law of diminishing returns kicks in for any tire/rim combination at some point.

    There is a new kind of 29er hookless rim (35mm outer width & 25mm depth) with new process. It's also tubeless-compatible. The weight is 460+/-15g(DH version)

    Got my selfie christmas presents yesterday and today. Rims are beautiful, really really beautiful. I've mailed envelopes heavier than both rims and the box they came in!

    350g and 357g! Unbelievably light. I was expecting 380-400g so no complaints. This one $340 purchase should drop over half a pound of rotational weight from my 26.5 Lb Long travel 29er. That's unreal value for the money.

    I defy you to name another place you could make that kind of weight savings and add stiffness and strength for any money (stomach staples aside). You could spend thousands on parts and accessories and never touch that kind of savings especially considering my starting point is M980 components.

    Oh FWIW I got the One Up components 42 tooth sprocket in the mail yesterday. Merry christmas to me...

    Yep, I like that the wheelset I'm building (LB hookless XC rims, Sapim Lasers and Bitex hubs) cost $250.00 less than ONE ENVE rim.

    When did you order yours? I ordered mine just before Xmas and I was told the other day mine are in sanding now. I'm hoping they ship before the Chinese New Year starts.

    Aw crap, ordered a wheelset last week hoping to beat the chinese new year, looks like they won't make it. My company get their plastic molded in china, its unreal how everything shuts down and how slowly they come back on line.

    Not chinese so not sure how it works in Light bike's area but its 15 days long. Everyone goes home and comes back at the same time. The gridlock is supposedly worst than our thanksgiving/christmas travel.

    Sorry just got back online. I ordered mine on January the 7th. Just checked the tracking and my rims have left the sorting center.

    I ordered a set before Christmas. They shipped on 1-8. According to the tracking:

    2014-01-08 11:34:00 XIAMEN Posting
    2014-01-08 12:29:13 XIAMEN Arrival at Sorting Center
    2014-01-08 13:46:30 XIAMEN Despatch from Sorting Center
    2014-01-08 21:24:59 XIAMEN Despatch from Sorting Center

    And that's the last update. I am wondering if the "posting" means that they are in transit from China to US?

    in the email they said it normally takes 4-7 days for delivery. Today will have been 7 days if you don't count Jan 8th. Maybe I'll come how to a surprise. Now I just have to figure out what hubs to use. These will be used on my CX bike.

    Hey so where are all y'all getting the ERD from? Page 18 has mention of it and if I remember correctly the ERD for the 21mm wide XC rims is supposedly 603, but didn't people say it was closer to 601 or something?

    I'm having Lace Mine 29 do mine so he will figure mine out.
    If I were you I would wait till you get them from what i have read the ERD varies.

    At 180lbs, is 28H a good option for the hookless XC rims? XC/race use. Thinking about ordering this weekend

    Hope they make it through quickly. My rims made it to the US in a day or two less than that estimated by LB, but as they arrived at US Customs in mid-Dec., they spent 1-2 weeks there.

    Sorry to get all grammar nazi on you. I know it's a doooshy thing to do (on my part). I'm sick of having to re-read stuff a few times to figure it out. Just putting periods in at the ends of sentences would go a long way towards making things flow.

    Cool-blue Rhythm Recieved two wheelsets XX1

    Ordered 30 mm and 27 mm hookless rims with Novatec D771/D772 hubs.Both set up 15 mm front 12-142 rear.Weights were 800 grams for both rear wheels which surprised me.Thought the 27s would be lighter than the 30s.Fronts are 30mm weighed 685 grams. 27mm weighed 675 grams. Wheels look awesome and aired right up tubeless with racing ralphs.

    It sounds like my rim order placed on January 12th will not be shipped prior to the Chinese New Year Holiday (Jan 31-Feb 15th). Anyway, I order the new process wider carbon mountain 29er rims clincher (tubeless-compatible) with a special request that both rims be 400g rather than the standard 390g. They will notify me when rims have been shipped and provide a tracking number. It sounds like I will have to pick up the rims from the post office and pay taxes, "We will declare the value at USD60 for 2pcs rims and write "sample only" & "bike rims" on the delivery document.
    Then you do not pay much for the tax. Is it OK for you? If it is not OK, please let me know what value you like us to declare on the delivery document."

    I'm considering going with brass nipples to negate the corrosion some users have experienced between aluminum nipples and carbon rims.

    So I had my first ride on these things. Must say I'm pretty impressed!

    I had two of the "wider am" rims built up locally with hope pro II, DT Comp spokes, and brass nipples. I was told they were some of the easiest rims the mechanic had ever built. In fact he was so impressed he ordered a couple for himself.

    Completed weight was 1680g. I added one layer of specialized tubeless tape and some valve stems. Schwalbe tires sealed up easily with the compressor. No "pop" sound like most other rims though.

    I got about 30miles on them over the weekend through some pretty technical and rocky trails. Factoring in some of the inevitable placebo effect I still think I could feel a pretty significant difference in acceleration and cornering stiffness coming off the Flow's (not ex) that I was running before. I'm not sure if it was my imagination but I also felt like they dampened vibration very well. The trail I rode was littered with small bumps and rough surfaces and It seemed like they were eating a little bit of that up. I rode a couple 2.5ft drops, and some nasty rock gardens and they held up just fine.

    Very happy so far, we'll see how they hold up.

    I've been trying to keep track of what everyone has been using for spokes and their tubeless set-up for the Light-Bicycle rims. Hope this helps:

    Spokes:

    Sapim Laser spokes
    Sapim CX-Ray
    DT Swiss Supercomp spokes
    DT Aerolite




    Tubeless Set-up:

    Bontrager Rhythm symmetrical strip with a Stan's valve
    Gorilla Tape



    Brass Nipples:
    DS Brass Nipples?
    Pillar Brass Nipples?

    Finally have the LB Bead hook-less 22mm inside rims built up. Sapim Laser spokes, Hex head Alum nipples, Hope hubs. 1589 grams. Tubeless set up is Stans wide tape and valve and they mounted up flawlessly. One ride and I was VERY impressed (shocked is more accurate) with the added stiffness over an Arch EX build with the same hubs, spokes with brass nipples. Sorry for the photo orientation and poor quality.

    Another 12hr solo race in the books on my wider AM LB rims with hooks. The race was mostly XC but had three 50 yard sections of just exposed solid rock. The sections looked like a bunch of broken concrete but none of it was loose. You could easily tip toe your way through but most of us faster riders where just picking the least gnarly line and doing our best to stay light and float over it at speed. Luckily the rocks where more shaped like super size stairs so you could avoid any pointy rock/rim strikes but at the speeds we were going it felt like my carbon frame might snap at any second. I always looked down at my tires to see if they were strait each lap and nothing every happened. I've gone from worrying about my wheels to worrying about my carbon HT frame.

    Can anyone give me the cliffnotes version of the advantages and disadvantages of the different spokes?

    Also, what is everyone building the tension of the rims to? TIA!

    The disadvantage of Rays and Aerolites vs. Revos is the price. There are no advantages unless you value the look of bladed spokes; same weight and performance at a huge cost premium.
    S.Comps are slightly thicker, which means slightly stiffer, no stronger, again at a large premium.
    You can probably guess what my go to spoke is.

    No reason to go over 110-120kgf max.

    I think you will be shocked at the difference compared to Crest rims. I am about 205lbs and originally went with the Arch EX which is considerably stiffer then the Crest. So, from a Crest to this rim will be a huge difference. Bonus, the rims are 15 grams lighter each then a Crest and a little wider. Time will tell how reliable they will be.

    The Crest wheels are an insignificant amount lighter, but I could really feel the difference in steering precision due to the massive amount stiffer the carbon wheels are.

    How about another facepalm for the founders of Light-Bicycle?

    Many people don't even realize that it is a company name. In the age of google and search term uniqueness, it would be hard to come up with a worse brand name. Light-Bicycle, love the rims, hate the name.

    sorry if LB or Light-Bicycle isn't your typical name to search for...

    Still a simple answer would of been enough... I guess you proved the theory of there isn't no such thing as a stupid question but only a stupid answer!

    Anyone try the bontrager rim strips in the hookless 22mm inside width rims yet?

    I can't wait to get them built up... the difference should be substantial at 190lbs(although closer to 180 by spring... hopefully!).

    Hi
    Im going to be building a wheelset with LB hookless rims.
    Hubs are gonna be the "new" Hope 40t, spokes Sapim D-light and alu nipples.
    About the rims i cant decide on the 22mm or the 30mm inside width?

    My riding is xc/trail nothing wild, and no drops over 1-2ft on occasion.
    Tires will be no bigger than Hans Dampf 2,35, and mostly a 2,25" Michelin Wildgripper.
    Frame is Transition Trans Am with a 120mm fork.

    Im thinking the 22mm inside rim, will be plenty strong for me.
    Is there a reason for me, to go 30mm inside rim for my riding??

    Best regards
    Thomas

    Actually the way I heard the quote was: there's no such thing as a stupid question, only stupid people...


    Just Kidding

    getting my hoops built up as we speak. Excited. The tech asked if I wanted brass or Al nipples and said that the brass didn't seize with the locktight he was building with as badly. Never heard of that before but I've always built with linseed oil...went Aluminum anyway.

    Loctite on the nipples? Other experienced wheelbuilders on this site would tell you to run away from that builder immediately...

    I dont have time to read 203 pages about these rims. Are the Light Bicycle hooked or hookless 29r rims going to hold up? I'm considering a set to go on my Dirty Harry hardtail to be used for XC racing, I'm 170 geared up. I'm a long time fan of American Classic and my other option is their 29r race wheel which weighs about the same. I know the AC are reliable and AC stands behind their rims, if I blow one out I can send it to them for a reasonable crash replacement. I know that tires stay on AC rims tubeless. Are there any issues with the LB rims cracking or tires blowing off?

    The wider American Classic and hookless from lightbikes are both new products. The hooked carbon have a good track IMO and should be no more prone to burping than Stans rims, which I have had good luck with.

    This hookless thing is just plain stupid and wrong on so many fronts......First of all Specialized did this as a cost savings measure, not an upgrade for performance. Second, when the rim loses the bead hook, the only thing keeping the tire on is the air pressure, lose the air pressure and the tire will burp or roll off. Those of you that are running higher pressures need not worry. Third, when you have a bead hook, the tire AND the bead hook share the load and work together. You are not stressing the tire alone. Fourth, by losing the bead hook you are losing lateral stiffness. The thickness of the bead accomplishes this, just like how an angle extrusion works....

    To answer the ridiculous statement that cars don't, have bead hooks.....well a car tire also has much stiffer sidewall and beads. Racing Off Road trucks do in fact have bead locks.......so stupid analogy. Don't think that every new development is a good one, some are just plain stupid.

    Keep to the subject, I thought we are discussing Bead Hooks.....Which Specialized came out with as a cost saving measure.....where did the Chinese argument come from in the post above ?? Keep drinking the Kool Aid...

    I will add that I rode a dead flat Ikon on a LB wider rim with bead hook and bonty strip for several miles and the tire stayed seated.

    I have not read a single report of anyone riding out a flat on the hookless.

    Or how many of us have ever rode out with a tire losing air ???? I think it is a ridiculous idea.....and people that are buying them don't have a clue as to what the bead does. Why put all that stress on the tire alone instead of sharing it between the rim ??

    It is far more likely for a tire to burp by rolling inwards toward the center of the rim. My own Bontrager rim strips, Ust rims, AmClass and Derby rims address this by having a small "bead lock" lip on the rim. The Lightbike/ Stans rims and the millions of car and motorcycle wheels do not. I have not heard of a epidemic of burps from these products and have not managed to burp my Arch/Flows running 20-25lbs

    As long as you and everyone else that bought into this hookless thing realize that Specialized did this for cost savings and not performance related reasons......Seems like every time there is a design change, everyone thinks it is an improvement.....not in this case.

    YaMon, have you ever ridden hookless rims yourself? Any first hand experience of hookless rims burping?

    If so, please enlighten us with backup of your claims from of your own experience.

    If not, please leave...

    If you like AC, have good customer experiences with AC, and the weight is the same, why bother switching?

    Exactly what load can the bead hook share when it is outside the bead? Due to tire pressure there is a radial load and sideways load on the bead - higher pressure = higher loads (contrary to what you said). I assume the beads on any decent tire are nearly impossible to stretch - and certainly not enough to get over the top of the rim wall, and probably not even enough to engage the bead hook - so the tire bead takes care of the radial load. I did have a Nokian tire literally blow off a Stan's rim about 10 years ago and never bought a Nokian again - point is, if the bead is weak, the hook isn't going to keep the tire on - that's a blow-off. A burp is when the bead moves to the center of the rim and has nothing to do with the bead hook. The rim wall must entirely handle the sideways load and for example Derby hookless rims in fact have thicker rim wall at the base than bead hook rims, therefore are stiffer and stronger. A u-shape structural extrusion does not have a bead hook because material there would not efficiently carry stress.

    Funny how the internet makes everyone an expert....so let me put it in a way that is irrefutable and put you in a position that will make you look stupid to argue...

    1. Specialized has said in no undeniable terms that they did this to reduce the cost. Not for any improvements to the design.

    2. There are no major rim manufacturers out there with all their engineers and manufacturing abilities that has adopted this hookless rim. Can you ask yourself why ?? or do you profess to be more knowledgeable than Enve, Easton, Reynolds, I9, Sram, and the ones I don't even know about.

    Well??

    Seriously, does anyone think that specialized have just reinvented the wheel?

    They are easier to manufacture, and are a poofteenth lighter - there may be some performance loss, but it's unlikely there's a performance gain. For certain, in his world, you can market just about any idea with success - people will believe any hocus pocus

    I have a set on two different bikes. I weigh about 200Lbs geared up. The wheels are as stiff as I have ever ridden and they are as true now as they were 5 months ago when I first started riding. I ride in a very rocky area and pound them, do some drops, etc. and they rock solid and durable. Best $400 I ever spent on a bike. I have the wide LB with the bead hook.

    Not sure what all the hoopla is about the no bead hook and how anyone would ever know if it is "Stronger". So what if it is, you would never be able to tell the difference between the two and to me it makes no sense.

    So you don't believe that a carbon sidewall of a rim that is equal thickness isn't stronger than a carbon side wall that has to get narrower at a point to create the hook?

    They didn't reinvent wheel, Hookless design was around a long time ago. I'f I'm not mistaken they added the hook years ago because of poor manufacturing tolerances on bike tires.

    Sooo, your answer is that they stick with it because, they don't do R&D, they are lazy and stick with old technology ??? If they saw an advantage, they would jump at it so fast it would make your head spin......

    I can tell you one thing.....if I was tearing down Porcupine Rim Trail or Downeville, I sure would want that bead there.....Then again maybe most of the fuys that are posting here don't really ride that hard. I take a lot of what is posted here with a ton of salt unless it is from a recognized rider ....like a Vanderham, McCaul, Bourdon, etc...Hell for a minute there I thought David C. was some expert till he posted a 15 year old GT with LB rims on it. Now how hard do you really think he pushes that thing ????

    You can all sit there and try to convince yourselves.....iot is a dumb idea and there are no advantages....actually is a disadvantage if you really push your bike hard. If you ride XC or on the beach, I guess it will hold.......

    Well Golly Gee Wizz.....You are offering a company to decrease their cost of manufacturing, make it lighter and yet, 7 of 8 of the manufacturers have not adopted this hookless design.......read between the lines people......there are no advantages. These companies err on the side of safety.....

    I'll take a stab at this one.....first a car and truck tire is not made the same way, ever notice how stiff the sidewall is. You bike tire goes under a lot more stress than a car tire. If you want to make a meaningful comparison, you would compare it to an off road vehicle......which DOES have a bead lock......

    (Cheap) Chinese Carbon Rims?

    I would love to see more rim profiles like the new AC Wide Lightning has. Short rim walls that allow the tire to inflate wider with a natural profile. Small rim hooks for that extra measure of, "well, if this hook does anything good then at least I have one." And finally the most important feature IMHO, bead hooks which keep the bead set and prevent it from slipping into the middle of the rim and burping. (Similar to Derby's)

    I have a set it the AC's as well as the Chinese 35mm titanium bead carbon's and dollar for dollar right now I would probably go with the AC's for ease of tubeless setup and the bead seat hook, while having the same weight and cost of the carbons but based in the US. But that's just me, to each his own.

I know the AC are reliable and AC stands behind their rims, if I blow one out I can send it to them for a reasonable crash replacement. I know that tires stay on AC rims tubeless. Are there any issues with the LB rims cracking or tires blowing off?
    All of your questions are answered in the 200 pages in this thread.

    I read the entire thread, then placed my order with LB. Thanks to all those who've been posting so much good info.

    (Cheap) Chinese Carbon Rims?

    Just an outsiders viewpoint. But the head hook is not needed in my opinion.

    Does it help keep the bead in place?? Yes when you lose pressure. It keeps the bead there.
    But for 99% of the time when you have adequate pressure the bead hook isn't doing anything.

    I think the beadhook design comes from when tire manufacturing process had pretty low QC.

    It's still pretty bad but it's all about finding a good tire to match your rim.

    It's a crummy deal but it's reality.

    I think the industry will adopt the beadless design. Just like the rims growing in width. I bet we see depths growing too. Deeper rims mean shorter and stronger spokes.

    They didn't reinvent wheel, Hookless design was around a long time ago. I'f I'm not mistaken they added the hook years ago because of poor manufacturing tolerances on bike tires.
    I think your question assumes something. A bead hook can either be made by thinning the wall or thickening the rest. Now if you decide the rim cannot be heavier than 340g for marketing reasons, then perhaps that's a good way to go.

    The bike industry generally us shocking for selling ******** - some is more obvious than others, but a cynical mind is IMO a better option in bike related stuff where proof of claims is never forthcoming .

    I have a set it the AC's as well as the Chinese 35mm titanium bead carbon's and dollar for dollar right now I would probably go with the AC's for ease of tubeless setup and the bead seat hook, while having the same weight and cost of the carbons but based in the US. But that's just me, to each his own.

    I'm guessing that's a made up profile? Just looking at it, there's no well to speak of, so the rim diameter would make for a very tight tyre fit, or a very loose tyre ( wow, remind you of a brand of rim.... . )

    For those who are new to the thread. I've been trying to keep track of what everyone has been using to build their set-up for the Light-Bicycle rims. Please let me know if I missed anything an I'll edit the post to provide more accurate and up to date information. Hope this helps!

    I've read the entire thread about two years ago and have been following it ever since. The most popular rim has been the wider 29er rim clincher (tubeless compatible) avaiable from Light Bicycle (carbon mountain bike rim-mountain bike rim,mountain rims,mtb rim,mtb rims,carbon mtb rim Light-Bicycle). There was a old process and the current "new process" rims that they have offered in this rim version. They claim from their website that the "new process" rims are stronger than the old process rims. There have been a handful of riders reporting rim fractures. However, no catastrophic failures have been reported. Most failures have been as a result of running ~<20psi tire pressure and striking a large object (mostly rocks the size of a curb or larger) at high speeds causing the rim to bottom out and strike the object.

    Riders have used the following materials to build their wheelsets:

    Spokes:

    Sapim Laser spokes
    Sapim CX-Ray
    DT Swiss Supercomp spokes
    DT Aerolite
    DT Revolutions




    Tubeless Set-up:

    Bontrager Rhythm symmetrical strip with a Stan's valve
    Stans Wide Tape (1 layer) with Stan's Valve
    Gorilla Tape with Stan's Valve



    Brass Nipples (to reduce the possibility of corrosion between aluminum nipples and carbon rim):
    DT Brass Nipples
    Pillar Brass Nipples

    Aluminum Nipples:
    Sapim Hex Head Alum. Nipples

    I may have missed it but does LB offer a 29er rim in the 35mm range. Love my P35s and at 1800g not too bad but lighter is nice too.

    This is the AC Wide Lightning. It would be a little stronger possibly as hokless.

    Bladed spokes are easier to tighten in that one can - literally - see if/when a spoke starts to twist. Also, you can prevent that by holding the bladed section at the very end (I use a slotted piece of hardwood). Of course this doesn't mean anything to the really-experienced wheelbuilders, all the more, if that tiny advantage at least doubles the price/spoke... True true.

    Yep, that thing that make it "easy" for a novice to true a wheel is a pain for someone who does it a lot. You have to hold them most of the time so that they don't turn/twist because it looks pretty dumb when bladed spokes are twisted but the wheel is true. While holding them may not seem like a big deal, it's annoying at the very least. On some wheels it's nearly impossible to work a special tool and hold a spoke that has nothing binding on either end (straight pull bladed). I don't think anyone that has bladed spokes does their own wheel maintenance.

    Stans Wide Tape (1 layer) and Stans Valve. By far quickest easiest tubeless set-up in my experience, that includes Stans rims. So far Maxxis, Specialized and Tioga tires have all worked perfectly.

    With 4 rocky/rough 20+ mile rides on them they have been excellent.

    I have a set of Enve XC clinchers, a set of CX tubulars and a set of XC tubulars all built with bladed spokes...by me. Only time I've had to perform spoke maintenance was when a stick went through my Enve rear wheel, and I snapped two spokes. Bladed spokes are more expensive, but as someone who doesn't build wheels all the time, its nice to be able to a) see and b) control spoke windup.

    You can see the spokes "wind up" when building a wheel if you use little "tape flags" on the spokes as you get towards final tension. I bet that this is far easier and quicker than using any of the tools to prevent bladed spokes from twisting. I definitely do not think that visualization of spoke "wind up" is any sort of selling point for bladed spokes. To each his own, I guess.

    I've never built with bladed spokes but I assumed you did not have to hold them (so long as they are J-bend or otherwise prevented from rotating at the hub). When making adjustments why can't you just turn the nipple more to account for the wind-up, and then turn it back until the windup is gone? For example, if you want a half turn adjustment and the spoke winds up a half turn, you make one full turn and then reverse a half turn. I have always done this anyway with round spokes (since bladed or not, you don't want your spokes wound-up) but then I'm no pro wheelbuilder. Seems like bladed spokes, again, would just make it easier to ensure no wind up.

    I have about 60miles on mine and loving them so far. I've gone through some nasty rock gardens and a few 3+ ft drops to flat and they've held up great. I've been running them on my Yelli Screamy hardtail. They seem stiffer laterally than the flows they replaced and also seem "take the edge off" chop on the trail. The reduced weight is noticeable spinning these up to speed and the matte non-branded look is quite nice.

    I just ordered rims and had them laced up locally. The shop owner laced them up and was extremely impressed with the overall quality and noted how easy they were to build. He was so impressed in fact that he ordered two sets of rims for himself!

    Rims: 30mm "Wider" 29er rims (hook type)
    Hubs: Hope Pro II (new 40t version)
    DT Swiss Comp spokes and brass nipples

    Total Weight (no valve stems or tape) 1680g

    I set them up with one layer of specialized tubeless tape which is pretty much stan's tape except blue and some stan's nipples. Schwalbe tires mounted up easy with a compressor and have yet to burp or leak air.

    I'll post up some pics shortly.

    You want to hold bladed spokes when building your wheel since they are weaker than round spokes when twisted.

    I define "light" 29er wheels as sub 1500g. That's not achievable with Hope hubs. But, I think with revos you'll be close to 1600g. Check out the DT spoke length calculator - it also calculates weight.

    Spoke thickness doesn't affect wheel stiffness. The difference is effectively just weight and cost. The only strength difference is if when something like a log gets jambed into your spokes. Otherwise, butted are not more susceptible to breaking. To overly simplify, this is because the thinner middle of the spoke takes the abuse rather than fatiguing the j-bend.

    I have to agree with this. My LB Wheelset is 1470 grams built 32H 3cross. I read reviews of carbon wheelsets with 28h spoke counts that weigh more and cost twice as much. My wife's wheelset that I built before I knew about this thread was Arch Rims, AC hubs, CX ray spokes. 1650 grams.

    I would have liked to use lighter hubs (I had a couple of issues with AC hubs) and could not justify the extra $$ for I9 with only a very small weight savings ,yes I do know how nice the I9 hubs are.

    Probably should have researched hubs a little more but I am happy with the new 40pt engagement Hope rear hub

    For around the price of Hopes, what can you really get that is lighter and as durable?
