    New question here. Best carbon DH bar

    I'm looking for a 710mm (28") DH bar for my all-mountain bike, and I'm wondering what people think the strongest carbon bar of that width is.

    Right now I'm looking at the Gravity Carbon bar
    http://www.fullspeedahead.com/fly.as...id=407&pid=746

    or the easton monkeylite DH
    http://www.eastonbike.com/PRODUCTS/B...ise_ml_dh.html


    unfortunately it seems like the easton only comes in 25.4 clamp size

    should I go with the easton and get a 25.4 stem?
    what would the strongest 31.8 carbon bar be?
    i really want 710 width and then to cut down if necessary, rather than get a 660mm carbon riser bar like raceface and truvativ make

    thanks for the input

    I would not buy any carbon fiber bars period

    I have watched 3 people go down......one will never ride again because of the bars

    Personally I've never ridden with carbon DH bars, but I've gotta say I wouldn't be at all keen on the idea myself. I'll take a bit of extra weight to avoid faceplanting my stem anyday (Whether or not this is likely I'm not expert on, just my instinct!)

    Carbon Bars are iffy for sure, but I hear the most common reason why they break in the most devistating fashion is because people overtighten the stem bolts.

    Yeah...carbon fiber definitely isn't meant for DH. The risk just isn't worth it.

    Carbon is okay for some

    You have to know what you are getting in to... don't overtighten the stem, check the bar regularly (you should do this with ANY bar) and be prepared to retire it if you gouge it. Scratching is fine, but if you get through the outer layer of carbon, ditch it. (again, this is the same with aluminum, but aluminum is more resistant to gouging)

    Maybe I wouldn't recommend a carbon bar for a 200lb freerider who likes to ride hard, but if you want to build a racing bike and are easy on your equipment, you will be fine. Or if, like me, you aren't a really aggressive rider. I prefer tech to speed, so I don't do many high speed get-offs.

    I have the Gravity carbon bar on one of my bikes, and my wife rides them on all of hers. No problems.

    The Gravity is superb, very very strong bar. Personally I would have no hesitation at all riding it for DH. I don't want to get into the whole carbon vs. aluminum debate, but the Gravity is far stronger than a lot of the aluminum bars out there and most of the carbon breakages you see are from people going way over the torque spec on their stem bolts.

    I broke my EC70 in one month.

    The FSA OS seems to be a little stronger. My buddy goes huge on his FSA and has no problems.

    I say go with with a ProTaper bar. They are almost the same weight.

    I use a FSA K-Force DH Carbon bar since over a year at my bike with zero problems but I'm only a 170lbs rider and smooth...
    I'll say go for it but watch out for deep scratches and replace if you are unsure after a hard crash.

    why do you want a carbon bar? is it for the weight savings? if so, why not swap out for some lighter tires instead of handlebars? a 1/2 pound difference of rotational weight is much larger and significant than the same difference in bar weight. id want a reliable bar that i dont have to worry about breaking anyways
    I went to the doctor and told him "hey doc, it hurts when I go like this" and the doc said "Does the rear feel too soft?"

    all mountain is another word for freeride. It is still trail riding and hitting drops but with around 5 inches of travel or so..........man you still are going to hit stuff....and they will still break

    Jesus, saying the word "carbon" around here is like walking into a room with a bowl of Ebola.

    Use a torque wrench, you'll be fine with the Gravity or the Easton.

    For those of you who actually know something about carbon bars, I'm a 160 lbs rider, and I race all the stuff I can. Most of the courses I ride aren't too crazy. I'm not ever hucking 20 foot drops. Would something like the Gravity carbon bar be ok? I don't think I'm ever too harsh on my bike and parts, excpet when I crash, but I break aluminum stuff when I crash too.

    I ride the Azonic B-52 bars. They are 28" and almost as light as Carben Bars.
    Ride!

    I personally wouldn't do it

    I guess if you take the time to inspect a carbon bar every time you ride and have the coin to replace it whenever it gets a scratch through the finish, then go for it. Personally, I prefer having a sternum, teeth, and aluminum bars that I don't worry about.

    Why, when a Protaper or a EA70 is only 20-30g heavier? I just done even see why someone would even take a chance.

    Use your best judgement... only you know your style of riding and ability.

    IMO, All-Mountain is so subjective it's ridiculous. Questions of this type are usually best posed to your closer riding buds who are more experienced and know your best.

    I ride wth a Diabolus bar/stem combo for trail riding. But then, my trail riding could easily be interpreted as freeriding by many.

    If you are silky smooth, light, easy on your equipment, and insist on a carbon bar, you should be fine trail riding as long as you are very diligent about bike maintenance.

    Good Luck !

    Context, sweetheart, context. I was referring to the fact that carbon bars require more attention than aluminum.

    Aluminum will bend USUALLY before it breaks. Carbon just breaks.

    I know when my EC70 broke it just about stuck me in the leg and that would not have been pretty.

    Carbon bars suck.

    carbon flexes..... but yes it does not "bend" as in take a new shape, it will just snap... Think composite hockey sticks......

    ya know, there is PROBABLY a reason that none of the big hit DH and FR bikes are made of carbon fiber as well... thanks, but no... i'd take an AL bar any day of the week and twice on sunday's over any carbon bar... now, that being said, if you were an XC racer/weight weenie then sure, why not, but I highly doubt any of the 20lb XC bikes could survive an 8ft drop without twisting up like a pretzel, even if the bars survived it, doubtful the frame or wheel would...

    Seeing what everyone says about carbon bars is always funny. Most are uneducated and only rely on what their buddies do. A nick or scratch can have serious consequences. Most of the crashes described were from someone not paying attention to their handlebars. I would say if you are a rider doing serious hucks A LOT, I might be a little leary (just a little). Also if you never look at your equipment, be leary. I race a little dh, do some decent drops, most with a decent tranny, do a little jumping and I've been using the FSA bars for over a year with no problems at all. I would grab a carbon bar over a lightweight alloy bar anyday.
    .... and actually many XC bikes can handle 8 ft drops, just most of the riders riding them can't do them properly for the bike to handle it.

    The bike that won the 06 men's Junior World Championship is made of carbon fiber, buddy...I believe it did the whole WC circuit before arriving in NZ for World's.



    You wanna know what Lahar's goal is? To build bikes that can last being raced competetively for five years. Carbon is FAR stronger than aluminum in regards to fatigue life.

    As long as you don't hamfist the installation of a decent set of carbon bars, you will be absolutely fine. Please emerge from the stone age, DH childrens.

    one example is all you can find??? for every one you can find i can show you a dozen that won't...

    carbon IS stronger, as you mention, but is much more susceptible to structural damage from impact than a quality AL forging... whack a rock with the swingarm real good and the AL bike keeps rolling, the carbon bike disintegrates... the arguement has never been about which is stronger on the CAD machine, it is mostly about practicality in this particular venue of racing... example, with nearly UNLIMITED BUDGETS, moto-x co's like honda and yamaha have not gone that route... the only company to ever put out a successful carbon race motorcycle was cagiva (road bike), and those bikes never worked properly anyway (they never won a race on the road - though that is not the fault of carbon fiber)... certainly it is possible to build a competitive race winning bike using carbon fiber as you note... but you can also drive a car to mexico using your feet, doesn't mean it's a good idea...

    Yes, saying carbon in this forum is liking opening a big can o worms. BUT, carbon has come a lot farther than being just an XC thing.... and that's it, I'm done, won't say no more....
