Hi,

I have a cube ams 130 full sus frame. It currently has a bb91-41 in, I want to fit an FSA crankset which is BB91. Will the BB91 fit, or are they different sizes?

Any help appreciated!!

Perhaps a bike forum would be a good place to ask?! Bikeradar forum is a good start...

Generally it's trial n error. I have changed my bb about 5 times over 10 years given i either got xtr I have been lucky n only twice had to change but when I put e thirteen one on it didn't fit firmly enough due to the wear on the bb. For safety just get another bb.

I had to dump a hope one which upset me but I still have it so it can go back on at some point.

The difficulty is each frame flares different at the rear...

Ps don't forget to change the bolts.

Dave.
