    Shimano bb91-41 integrated bottom bracket

    I have a 2009 lapierre pro race 400, which has an integrated bottom bracket, a bb91-41, and was wondering if there is a way to put a standard bottom bracket on it, external or internal, something like an adaptor, or if you can purchase different bearing sets, such as ceramics or for differnent crank brands.

    Thank you
