Cheers fella, is it 122.5 then or 127.5 ? confused :roll: :roll: :roll:

With all the Cook CBR & RSR cranks I've owned, it seems that I've gotten away with a 122.5 mm 90% of the time. If you have an aluminum frame with fat chainstays, then you might need something longer so the chainrings don't rub.

I have been offered a 122 syncros Ti one , do you peeps think that the .5mm is going to make any odds, or is it a matter of getting the grinder out...
