Saturday I plan to swap the SRAM chainset on the best bike for another SRAM one with carbon arms. Will be fitting it to the existing bottom bracket, which is a Hope with the usual Truvativ GPX adapters fitted. To my mind, with correct application of my trusty torque wrench the new chainset (same numbers of teeth, swapping compact for compact) should end up precisely located where the old one currently is and the sweet shifting front mech should need no adjustment. What says the hive mind? Should I postpone the swap to a day when I have losts of mech fettling time free or am I good to go?
