BB size ? and a bonus ?Birddog
Jun 5, 2003 6:27 AM
I am shopping for an Isis BB. I will be using FSA Team Issue cranks (172.5) and installing the BB on my Serotta CSi. I know the BB shell is 68, and English threads, but how do I determine shaft length? Also, does anybody have any feedback on an FSA Duron Threaded Headset?
Thanks,
Birddog

Just installed an FSA triple ISIS. Thought my old Shimano tool would work, but it was way too short. Glad I had William at Wise Cycle Buys throw in an installation tool.

But if you flip the coin.. I have a Race Face ISIS BB tool and it works just fine on my Shimano BBs. The little splines are deeper for the ISIS BB, but the tool for them works in a Shimano. So if you are only going to have 1 tool, get the ISIS so it works on both.
