This bearing is most commonly used as a direct replacement for bearings in Shimano-type external-cup bottom brackets and cranksets with 24 mm spindles.

Enduro bearings are available in high-carbon chromium steel and 440C stainless steel, as well as ceramic-hybrid and XD-15 versions with ceramic or stainless steel balls. The bearings are designed with the deepest possible grooves to accommodate the largest possible balls. Dual-lip seals run in a micro-groove to create a full labyrinth seal that protects against the elements.
