Hi.

I'm in need of a new bottom bracket since I'm replacing the ISIS cranks on my Kona Hoss 2007 bike, which came with a Race Face ISIS BB.

I'm not sure which size to get for the frame - is there a way of checking without removing the lot?

I'm thinking Shimano BB70, which is a 68/73mm to go with the SLX Hollowtech 2 Crankset.

Is there anything else I need to be aware of with the upgrade?

Thanks!

    HT 2 cranksets come with BB cups as standard. and they will fit either width.

    just get the BB shell faced.
