    Trouble Replacing Rear Wheel: 2015 Specialized Camber Expert Evo


    I'm exhausted and frustrated on this. Please help..

    After several broken spokes, I was told my rear wheel needed replaced. I live in rural MO and the one LBS acted like they didn't have time for me so here I am trying to figure this out for myself. I did a ton of research but apparently not enough because I'm in the process of returning the first replacement wheel I bought (148 is too wide).

    This is the frame I'm riding:https://www.specializedconceptstore....rt-carbon-evo/

    I finally figured out that my dropout is 142mm (or maybe 142+?). The old wheel was somehow 135mm and I don't understand how that worked out, but I bought the bike used as a "custom build." oops.

    The drivetrain is a 2x10 Shimano XTR.

    Using calipers, I found the through axle measures 158mm in length from the inside of the shoulder to the beginning of the threads, then it has 9mm of fine threads (I know they're fine because I'm also returning a through axle...)

    I recently upgraded to 2.3" tires so I'd like a rear wheel optimized for this tire width (looks like 30mm). I have 6-bolt disc brakes.

    Which wheel do I need? Would I be better off going to 1x11 drivetrain while I'm at it? or 1x12? is this even possible?

    I am so confused - it seems every manufacturer measures things differently and I can't find any 142/Shimano/29. I really just want to get back on the trail.

    This is the one I might try next, but I need a little more confidence before I end up going through the whole return process again:

    Thank you so much for your expertise.

    The rear hub spec is in the link you posted:

    REAR HUB Roval Traverse 142+, XX1 driver body, 12mm thru-axle, 28h

    I would talk to whoever you order a wheel from and tell them what you had and what you want the new wheel to be able to do and they’ll get you sorted out.

    Slow down and take things one at a time.

    You only need to replace the wheel, not the axle (just use the existing one), and not the drivetrain. Not now anyway.

    What you need is a 142mm hub with a Shimano freehub, laced to a ~29mm x 29" rim.

    The Jenson link you included is for a decent rim laced to a crap hub, and probably built by a machine. You can/should do better, since you've already had problems with broken spokes to begin with.

    There are lots and lots of online wheelbuilders that can build a quality wheel to match your specs in under an hour. I am one of them. Click the link in my signature, below, if you have further questions.

    Appreciate the responses. I'm finally back on the trails and just took my new Raceface Turbine R rear for a spin. Aside from the huge headache of it arriving with a missing washer, I like it a lot. I bought a matching front because I got a good deal on a set but haven't mounted the front up yet.
