    Middleburn ISIS Cranks -- Bolts? (Drivetrain X-Post)

    Posted this question on the Drivetrain board to no response. I know some folks here run Middleburns, so...

    Just ordered a set of ISIS Middleburn cranks and a Crank Brothers Cobalt bottom bracket. I assumed the bottom bracket would come with crank bolts, but it did not. Is there any reason I would need the Middleburn crank bolts, or should any old set of crank bolts from the LBS do?

    it's not uncommon that ISIS and square taper BB's don't come with crank bolts.

    It probably uses standard M8 crank bolts....but just ring up Crank Brothers and confirm or pop them an email, they are super helpful.

    Any bolts will do so long as they're the correct size.

    The Cobalt uses M15 bolts.
