    Yeti ARC and PBC/Topline Cranks?

    Hello!
    I finally got my 95 ARC and some nice blue PBC Cranks.
    The problem is this things won`t fit together at all.
    I got a bb with 131mm axle, but this far to short!
    I saw some ARCs in the Galerie of yetifan.com with these cranks installed.

    What bb fits this combination?

    Thanks for your help!

    I'm surprised that a 131mm is too narrow.

    I know that if you want to run older cook bros you need 126-128's or so.

    Do the cranks sit real deep on the spindle (like the square taper is worn or damaged)?

    Shoot some pictures and I'm sure we can help better.

    wow, how fat are those yeti stays? I'm running a 128 mm spindle to get the toplines to work. In my case the bike came with a 116 (I think), so add at least 12mm from your old bb to get this to work.

    Wow! Me Too.

    Topline's called for 122.5 or 127.5 spindles just like comperable Shimano cranks.

    Wow, it sounds like the square taper holes could be worn to me. Could it be possible that the previous owner of these crank may have over torqued them on the bottom bracket? You can try comparing the holes of the two crank arms and see if there's any noticeable difference.

    Thank you guys for your help
    I think the problem is solved, the bb i got was really crap.
    The left side of the axle was shorter than the right side
    I wonder what thats good for?

    I think i`ll get me a quality 127mm bb and this thing should spin.....

    Im still searching for a Ringle Moby in silver, 26,8 to fit my ARC.
    It`s the last part missing, so pleeez help me out

    Cheers!
