    Crank and Bottom Bracket Quest.

    I just bought a 2011 Trek Superfly SS Frameset, Wondering if the Cannondale Hollowgram SL cranks or any BB30 cranks would fit the standard 73mm bottombracket, Is this possible?

    I would think not. BB30 cranks require a 42mm ID bb shell to fit the bearings. In short, the bearings wouldn't fit, and they are press fit anyway.
    I see hills.

    I want to climb them.

    This might work...?

    Ned's SS Rockhopper with OS cranks

    "The most interesting component was the S-Works FACT OSBB carbon crankset with a Rotor chainring that fitted the threaded ecentric bottom bracket through the use of Zipp’s Vuma Quad Bottom Bracket. The Zipp external bearing BB retrofits the crank’s 30mm axle to a standard bottom bracket shell."
