BB BB392EVO to 24 mm Shimano reducer bottom bracket
A 24 mm Shimano crank runs in a BB392EVO 46 mm bore using a reducer BB that presses into the wide 91.5 mm shell and steps down to 24 mm.
The shell is 91.5 mm wide, so the reducer is longer than a BB386EVO one. Match the reducer to BB392EVO, not the road 386 version.
