Hi Everyone,
I am wondering if this crankset which is an FSA Omega crankset is compatible/ can be installed on a BB30 bottom bracket?

Thanks for any insight you can provide

My 2014 Sirrus came with this crankset. When i searched for a new BB for this set i found that the spindle on this crankset is 19mm wide and the only BB that works with it is the one that comes with it.

so are you saying the spindle should fit into a bb30 with the bb4000 bracket that comes with it?

No it's not compatible with BB30.

It's very much like a Shimano external BB but with a 19mm axle. I use one on my commuter bike (which originally came with a square taper BB).

Thanks, so confusing!!

For my CAADX I bought this;

Are you simply wanting to replace the crankset without replacing the BB? If so you need to know what the BB is that is currently in it or what the crank is that is currently in it. Then you'll know the spindle size of the crank that you must look for.

But if you know what your BB shell is actually made for, then you can buy cranksets that also have BB's for them that will fit your BB shell and not have to worry about spindle diameter.
