    TBH I have not had much joy with Shimano press fit BB.

    This time, follwoing advise from another member, I bought and fitted a RWC ceramic jobbie.

    Silky smooth.

    IIRC, there is a guy called Chris at RWC and if you tell him what frame you have along with the dimesions, he should be able to tell you which model you need.

    i ordered the shimano BB but if that goes pareshaped too i will look into the guys you suggested, thanks :)

    can you tell me why you have not had much luck with the shimano BB?

    I think the bearings are not big enough.

    I have been through a few pressfit BBs. The Shimano model seems to be poorly sealed, doesn't last long in the wet and is not built to be serviced, at least, I couldn't overhaul it without destroying the plastic casing. On the other hand, it is easy to fit and relatively cheap. I got one here in France for 20 euros!
