    New question here. Anyone Riding Carbon Bars?

    I am curious if anyone is running the Easton Monkeylite XC (mx) bar. My LBS is clearing some stock and has these for sale and I was wondering if anyone has run them with any success or failure. I do a decent amount of 4footers and Tech DH and I know a couple guys who ride XC and run the SL version and have never had an Issue. And supposedly the MX is beefier than the regular XC bar. I just don't want to have a bar snap on me while riding. Like a buddy did although to be honest it was because he over torqued his brakes and cracked the bar.

    My other option is the EA70 Monkeybar. Good old fashioned aluminum.

    I run the MX's on my "all mountain" bike (Foes FXR) and the XC's on my "light bike" (Ventana Saltemantes) .

    What bike are you putting them on? 4" drops should not be done on XC bars!

    I ride a blur LT. And the Easton Site says

    I would assume that the limits of XC includes a few drops. But I know it's Advertising Speak so who knows. I guess I could go with the DH bar but that thing is huge and I don't want to cut that much off the bar to make it rideable (710mm) and it's a high sweep I wanted a low or mid. I am guessing that the EA70 Monkey is the way to go. I guess I was just hoping to save a few grams.

    You'll be fine. Just install the bar properly, don't overtighten the bolts and inspect for damage when you crash.

    I huck the crap out of my "all mountain" bike with Answer carbon bars and they don't even have nanotubes. Gasp.

    I'm sure they're not going to "suddenly break" while riding... I'm pretty sure "suddenly breaking" is an urban legend...

    Go for the carbon. I guess that's what I'm saying.

    A few years back at Pedro Fest in Lanesboro, MA, we were descending from Jimminy Peak and a guy on a tricked-out Intense Tracer had his Easton EC90 MonkeyBar Lite SL snap near the stem. I'm not sure what happened because he was behind me, but he was okay. I saw him back at the camp with a no-name aluminum bar.

    I have a Race Face Next SL carbon bar on my Blur. So far so good, but I'm kinda skeeved at the whole carbon fiber deal.

    LOL!...I'm living dangerously too, Kauai. I'm running the Easton Monkey Lite XC carbon bar on my Nomad and an Answer ProTaper XC carbon bar on one of my Bullits. Like Squeak suggested, I look at those bars frequently around the stem area, and I always inspect them after a decent get-off. They've been golden so far...over a year. I don't huck or jump big, but I get some air and ride rocky stuff fast and hard. I think most manufacturers of these bars...at least the good ones like Answer and Easton...probably err on the side of safety and liability.

    I thought that I read somewhere

    that carbon bars have a 3 year life span (you should change them out after 3 years) even if you haven't had bad crashes, just because of the general fatigue from repeted shocks of riding.

    I'm not sure if this is true or not, but I THINK I remember reading that somewhere?

    one of those Mean-time-between-failures things (like hard drives and laser printers)

    I don't know, anybody seen something like that?

    I hear that about Aluminum bars- every two years or so. Carbon bars are great. I've used the Easton EC70s for years (two of them) and am getting ready to get either a RaceFace gravity (heavier-duty carbon) or a Syncros Bulk (similar to Easton). I don't think carbon has a fatigue life but I'm not 100% sure.

    Easton claims the EC70 or monkeylite XC bars, are ~300% stronger than their competitors. Check out this animation its pretty cool.

    I am also leary about carbon bars. I just bought a Truvativ Team Carbon bar... I haven't installed it yet since I need to get a torque wrench first...but I am a little worried about it snapping on me, though the failure characteristics of carbon is more of a crack... I've never seen carbon just snap...

    OK, well obviously in high impacts carbon will snap right off...actually, any material will snap off in a high enough impact...

    In the MTB world...in a pure XC/trail conditions, I can see that happening...
    But, I could be wrong...

    I currently have waiting to be installed a CF seatpost and handle bar... I'll let you know how it works out... My riding style is very gentle compared to your all out ride it like you stole it types...

    Steel and titanium should bend (well, I guess they could snap but the impacts would have to be pretty incredible).

    I've been running the same set of easton monkey light XC's for two years now on my all mountain bike with no problems. I ride pretty hard but the biggest drop I have done on the bike with them was about 4 feet to a nice transition. The largest drop to flat I've done with them was around 3 feet. that said, I dont recommend doing it with XC oriented bars, and anything more than 4 feet would not be advised.I
    have had one small problem out of them. I went down in a rock garden and smacked the end of the bar pretty hard and it bascally crushed about 3/4" of the tube . The lock on grip wouldn't clamp on properly anymore.
    luckily, I had been planning on narrowing the bars down some anyway and I just hacked off the damaged part of the tube.

    As long as you arent over tightening the stem the bar should be ok. Like some ppl when told to hand tighten something they end up giving it a good crank because they figure hand tight means going as hard as you can by hand. Also when installing on a stem with a 4 bolt face (like most stems come nowadays anyways) make sure its going on straight and with equal spacing and your turning each bolt only so much. My friend had his carbon bar cracked because the shop didnt know any better and installed the face on crooked.


    If your falling alot as well or starting out mtbing I wouldnt recommend a CF bar.

    Here´s my modest input.

    Rode a Pro 31,6mm diameter carbon seatpost for two years without any problems. I weigh ~225lbs w/ gear and am not so smooth rider. Unfortunately the size was wrong for my new frame so I went for aluminium one as carbon ones weren´t available at my LBS.

    Now riding only a carbon handlebar, Azonic CF 1. Anyone had problems with those? Feels very rigid and strong, fitted into a thomson stem. I´m a bit concerned that the set is 25,4mm, not OS.

    I don't understand the logic behind that... Why throw it out after two years...?
    So I guess buying a used carbon bar is out of the question...?
    Since when does carbon fiber have a shelf life?
    I'm pretty sure things degrade with time...but two years...?

    CF is quite strong under very specific circumstances,circumstances that are not highly probable for MTB.If you can manage to not damage it when installing it onto the stem or when attaching brake levers or shifters,and then ride in such a way where you NEVER scratch or ding it AND not do big jumps.....then theoretically it will last forever.Take a good look at the handle bars out there and count how many have zero damage and are in PERFECT condition,you would be hard pressed to find some if any at all.Any CF proponent will tell you to replace your CF bars if they suffer minor damage,aluminum should also be subject to the same standard but at least it will bend most of the time if it fails (but can also snap) where CF will just snap.That's why they recommend you replace your CF bars every one to two years.

    What about the carbon bars that have a thin aluminum tube on the inside?

    I bought my CF bar used. I inspected it very carefully and its intacted... There are just light indentations on the clear-coat where the brake levers were installed. It seems pretty sturdy and it has aluminum endcaps so you can install bar-ends...though I don't plan to.

    If I would have known about the delicacies of CF bars, I probably wouldn't have bought a used one...

    That would get extremely expensive to replace a CF bar every one to two years at $140 a pop...

    This is simply my opinion but I would not ride used CF parts because I have no way of knowing how they were used or misused by the previous owner.

    New Ti as in Titanium...? Is it lighter or comprable to CF...?
    Where...? When I was shopping for a new handle bar I didn't come across any affordable Ti bars...? Ti would have a more elevated bling bling status...

    Ti isnt as light as CF and is generaly heavier than aluminium alloy but it more wear resistant than both. Most of the time you need a spacer since bars come in at 22.2mm since its hard to machine. I have a Ti bar that comes in at 240 grams but its comparable to 500 gram steel downhill bar, strong stuff. I would just inspect your bar and if it looks good use it just check it out before each ride.

    I had a carbon bar snap because the disk brake lever was a pinch bolt style clamp and it deformed the carbon, I got it warrantied and going to give it another try with different disk brakes I still have a scar from the end of the bar stabing me in the side, but it healed smooth and will fade.

    Oh thanks for the link to the easton page I like pressing the TEST and having it slam down

    Wasn't there myself, but recently someone a friend knows had his easton carbon bars snap clean off at the stem while motoring down a rough track. He's got stitches and bruises and it can't have been pretty. Aluminium bars fail aswell though.

    No problems with Monkey Lite's

    I've had the same Easton Monkey Lites on my Santa Cruz since 2000. I don't do big drops but I've had some spectacular over the bars crashes and I ride a lot of rock gardens in So. Cal. with no ill effects.

    I wish i took pictures, but I have gotten the replacement bar back already. It looked kinda cool you could see the weave and layers of carbon fiber.

    I have been using 31.8 Easton Monkeylite CNT riser for a year now and its been good for me. And I am very confident even when barreling down at 32-35mph on a rough terrain. Although somebody had told me that CNT is different from CF is this true. But I cant go wrong with my setup 31.8 on Thomson X4 stem its the way to go.

    I use the same setup, 31.8 Monkey Lite DH riser and a 50mm Thomson X4, no problems for a year so far and I crash a LOT.

    I don't get what your point is when that article states this
    "Carbon frames now are very popular, but carbon handlebars have been met
    with skepticism. There is no reason for this, because the carbon handlebars
    in our test broke all records. 75% of all tested samples passed the test. In
    the handlebar test in BIKE 10/02, mostly aluminum handlebars were tested.
    Back then, less than 30% passed."

    BTW all three of my bikes have Carbon Easton Monkeylites on them with my Enduro running the Monkeylite DH.

    The (mixed in) kind words are not to harm the bicycle industry,look at the numbers.

    This is what I understood from the article:
    1-30% of the aluminum bars passed their testes in 2002.
    2-75% of the CF bars passed their testes in 2006.But I doubt that this test can factor in the kind of real world damage that people like Sir Crash-A-Lot (Flynnet) accumulate during their rides,even though they did simulate light crashes during their tests.
    I would not ride handlebars that failed %25 (let alone %70!) over the course of it`s life,especially knowing that the ones that are going to break will do so earlier on.
    Imagine if these guys tested stems and forks too!Do you imagine that those components would handle stress any better (especially the fork)?Add up all these risk factors on an all CF component ride and ask yourself this question,is CF worth the weight savings VS. the risk to your health?

    Bars have testes to pass?....

    Sounds like following the mfg instructions carefully works.

    Looks like Easton from that animation builds a pretty big 'safety factor' into their product.
    Though it's a bit dubious when they don't specifically name the competition, or specific models...
    O-Jo-Mo-Jo!
