    F5 rear wheel spacing?

    is it 135mm or 150 mm? Can't find it on the webpage

    also, what ISCG tabs does it use?

    old or 05?

    If it was 150mm you wouldn't have room for a floating brake without having to run a 100mm bottom bracket, and have the rear of the swingarm about 10feet wide.

    Any way it's a zero dish 135mm wheel, so It's way stronger than a standard dish rear wheel

    Didn't think about the floating brake...
    I guess it does bring some positives to it other than weight savings, I can run my other wheelset on this bike.

    I remember saying this like, 6 months ago?
    Alan put the dimensions on the website!

    yep 135 by 12 because of the floating brake. Of course you could design a floater which attaches indirectly to the axle and doesnt fall off when you remove the wheel, just like the Cannondale Gemini or Judge (150mm).

    P.S. the Cdale uses a 83mm bb

    yuppers... like others have mentioned... 135X12... Wheel might have to be dished a littlebit towards the brake side but that can be done easily with the wheel on the bike... or, you could use a 150X12mm wheel without the floating brake. The brake mounts straight on the swingarm near the dropouts... gonna want to ask Chumba about that... The demo bike Walter brought out to the bay area had one of those...

    I'm just going 135mm, it's perfect this way since I can switch wheelsets between the two bikes.

    You won't be able to switch wheelsets without re-dishing the wheel. Not something I'd want to be doing often. but at least you won't have to buy a new set of wheels

    im perty shure that you gotta run a 135 with the fixed brake mount as well....not a 100% (someone know this for shur?) I am putting on a fixed brake mount as soon as i get home. That is what lars runs and all the other pros that ride the chumba for that matter. I love chumba but they have some work to do on the floater before i will put it back on

    150mm won't work period. without the floater it's 145mm. there must be some sort of spacer for the fixed brake mount?
