• Just had a call from Seabass (who are building this up for me) and there is a problem with the axle length on the Rotor cranks - basically it's too short for this threaded BB set-up. The mechanic reckons it might be cos it's for press-fit BBs.

    I knew about axle diameters and I researched BB options pretty thoroughly but I had no idea about different axle lengths... so, if I'm now shopping for a new axle, does anyone know what length I'm searching for? Obvs, this is a standard 68mm BB shell.

    EDIT: Turns out it's the spider that's wrong... made for some kind of proprietary Cervelo design. I think I have to switch spiders... so no bike intil that's done; the saga continues.

  • Grrr! Can't go wrong with square taper bb and cranks, flog the Rotors, get summat from White Industries, job done.

    The spider is detachable but not the axle as far as I'm aware, and it's the axles that came short for a cervelo specific crankset.
