hi, two things

- can you fit BB30 specific cranks on a non BB30 specific bike, like a ribble sportive?

- how does one cut down a carbon fork steerer, is it wiser to let your LBS do it?

    1. You need a BB30 BB for a BB30 crankset.

    2. You cut a steerer with a saw, ideally 32tpi.

    Thanks redddragon, I'm confused, when you say bottom bracket do you mean the part of the frame the cranks fit into or the cups/axle the crank arms fit onto? Forgive me for the dumb question I'm just a tad confused. I assumed bb30 was somsehing that was specific to the frame dimensions.

    For clarity - a BB30 crankset uses over-size, press-fit bearings that simply won't fit a regular threaded BB shell.
    Make mine an Italian, with Campagnolo on the side..

    With reference to cutting the steerer unless you have a good quality new 32tpi blade and something to hold the fork carefully in place e.g. park cutting guide I would say just get a lbs to do the job,easy with the right tools a possible expensive nightmare without!
