The Wheels Manufacturing 386 EVO A/C Thread-together Bottom Bracket pairs machined aluminum cups with Enduro angular contact sealed bearings to support a 30mm crank spindle. It fits BB386EVO, BB392EVO, BBRIGHT, and PF30/83 shells ranging from 79mm to 92mm wide, with a 46mm shell inner diameter and an 86.5mm over-bearing width in an 86.5mm shell.
Its cups thread together for a stable interface that promotes bearing life and simplifies installation and maintenance. Supplied silicone dust shields keep contaminants away from the bearings, and the bottom bracket accepts 24mm and 24/22mm cranksets with Wheels Manufacturing's 386EVO crank adapters. The unit uses a 16-notch, 48.5mm tool pattern and has a claimed weight of 124 grams.
