Bottom Brackets

A bottom bracket should spin smooth and stay silent. Ours do both. Custom bearings and high-performance seals deliver supreme durability, whether you're grinding gravel centuries or smashing bike park laps.

Threaded bottom brackets fit BSA and T47 frames with 68mm, 73mm, 83mm, and 100mm shells. Available for 30mm spindles (Race and Plus cranks) or 24mm spindles (Base cranks). The gravel-specific 68mm BSA version fits road shells with no spacers required.

Press-fit bottom brackets are compatible with BB92, PF30, and BB30 frames. Our PF30 and BB30 options use a thread-together system that eliminates the creaks common in standard press-fit designs. The BB92 version uses industry-exclusive dual-row bearings to fit big performance into a compact shell, with a center tube to seal everything up.

Every e*thirteen bottom bracket comes with a 1-year no-questions-asked guarantee. If it creaks, we replace it.
