TOP FAQ
This BB is compatible with frames using BSA threaded BB shells and with cranks using M24/GXP spindles only.
M24/GXP cranks have a steel spindle that have a 24mm drive side and a step-down to 22mm on the non-drive side. See image above.
You need a 16-notch external BB cup tool with a 44mm ID.
Park Tools’ BBT-19.2 is an example.
