    Wheels Mfg BB30 reducer install question


    I originally posted this in the Cannondale forum, sorry for the double posting.

    I have a question about installing the Wheels Mfg BB30 to SRAM GXP reducers.

    I have pushed the reducers in and installed the crankset. When I tighten down the crank about as tight as I did when it was installed with standard bb cups, since the directions said to install as you would a standard crank once reducers are pushed in.

    It seems the crank does not spin as freely as I would expect. When I back off on the tourque on the crank it spins a bit more freely, but I fear that it may loosen up while riding.

    Any thoughts?

    Thank you.

    There is no reason that the system is going to undo the torqued bolts and move itself. It is possible that the reducer could wear in or compress some, which is why it is always a good idea to recheck your adjustments after the first ride or two.

    In this case, adjust the preload to the same standard as before - no play, turns smoothly.

    Follow the directions for the crank and torque to the proper spec. If the side to side play is gone and the crank still spins, then it is fine. There is quite a bit of drag in the external BB seals vs. the older style cartridge bearings.

    If the crank does not spin at all or with a lot of force, then something is wrong and the crank is bottoming out on the adapters.
    You can't fix stupid.

    Thanks for the replies, I backed off some of the pressure on the crankset and took it for a long ride last night and everything seems fine.
