    My carbon 650b build.

    I don't understand... If carbon is supposed to be so much stiffer than alloy, how does it "soak up bumps"?

    It's an honest question.

    That's the beauty of carbon. It's all in the design and layup of the carbon. Large main tube, BB area, and chain stays make the bike efficient while thin seat stays give the bike a soft feel on the trails.

    Looks good. The Wolfstooth/XX1/RFNW is also a great mod plus inexpensive. CF when built right can feel very nice on the trail or on the road.

    Are all those carbon frames basically the same on ebay?
    I saw different numbers, but they look about the same to me.
    BTW- nice ride!

    I did read that some have the larger rear axle size...I got some 650b parts...I might get one.I used to be scared of carbon frames since I'm a big guy.(around 230)...but since I can't ride too hard anyway due to an injury,i'm pretty sure I can ride one-no problems.

    the blanket statement of carbon is stiffer than alloy (technically alloys can be anything including aluminum, steel, titanium) is too broad to give a valid answer.

    Carbon can be stronger than an alu alloy, but allow for flexibility depending on its materials, manufacturing and design....

    It looks like the Scott for sure. The Jamis has that extra fin-like material above the top tube at the seat tube junction.

    I don't know how much in-house engineering Scott does but they may be like Jamis. They don't have any in-house engineering. They, like many companies, ask for certain production specs based off of what the Taiwanese and Chinese OEMs can make. It's called a catalogue bike. You can order volume and sizes based on their design and make changes if you pay for them but all of the engineering, pre-production and manufacturing is done overseas. I know for a fact that Spec'd, for example, has in-house engineering and design staff that will create all of the CAD, fea, etc and then ask somebody to pull it off (Merida).

    I think the Jamis looks better, for whatever that's worth...

    Tire clearance is very good.

    And it handles the vortex great. Just needs a better rider on it...

    My carbon 650b build.

    Hi,

    I have a problem with the upper bearing of the headset. The bottom fits perfect but the upper bearing is smaller than the cup, and this cup seems not having enough depth. The size of the upper bearing is standard IS42: 41.8mm 45º 45º 8mm height... But, look these pics

    My lbs put the headset in so im not sure which one, but i think he said it was a 110. The headset would not tighten all the way. It popped and cracked and creaked. My buddy who is a pro mechanic for 25 years was tired of messing with it so he replaced everything even the star nut. No more problems.

    I have the exactly same problem with my Neco Headset could not get it to stop creaking, so I bought FSA headset and hopefully it will solve my problem.

    The Neco headset is definitely junk. Mine fit fine and didn't creak, but was showing rust after only a few rides (got wet on one of the rides). My FM 136 used the FSA .042 ACB headset fitment. I replaced it and all has been fine since. I would just decline their $15 headset and buy the FSA separately (costs about $40).

    Hi, this is my first build & just received this frame. I am a little confused by this headset issue. What was the one you guys used that worked? Looking at the 29er thread (I think same headset for that frame) the cane creek IS42 top & IS52 bottom is what is best.

    1 more thing, the travel on the fork? Any idea what this frame was designed for like 100 or maybe 120?

    Thank you & happy new year!

    Which is "this frame"? Did you buy the FM136? If so, the headset you need to buy is the FSA Orbit C 40 (No.042 ACB).

    FSA Orbit C 40 Tapered for 42mm 52mm ID Headtube 1 1 8" to 1 5" Steerer | eBay

    The FM 136 is designed for a 100mm fork.

    What is that though, could you say what the brand & model is.
    The frame I got is the fr503, the one that the op has I think. Not sure if the fm136 has the same design.

    I have the same question. Could one of you post an approximate cost for your build? I'm very interested in building a hard tail 650b and wondering if I can come-up with the funds to build one. Until now, with the high priced frames I was looking at, I wasn't sure I could but this frame looks good and the cost is very reasonable! Thanks.

    My carbon 650b build.

    2,5k€ more less, I had some components on stock, so my real cost was a little bit behind. The bike is 8,5kg

    Thanks Patrul, that helps a lot. It looks great, and I bet at the weight it's also a lot of fun to ride.
