BSC’s LMT-1 is designed to install and remove the lock ring on Certain Cannondale Hollowgram, FSA MegaExo and BB386EVO, and Specialized/SWorks Cranksets.
It features a close tolerance fit over the 30mm axle for stability and can be driven with a 36mm socket or crows foot spanner to tighten to specified torque.
