e*thirteen Bottom Brackets

Smooth, sealed and creak-free

e*thirteen bottom brackets use custom bearings and high-performance seals for long life and a smooth spin. Choose a 30mm spindle BB for Helix Race, Helix Race GR and Helix Race Carbon cranks, or a 24mm spindle BB for Helix Core and other 24mm cranks.

Threaded options cover BSA 68/73, 83 and 100mm shells and T47; press fit options cover BB92, PF30 and BB30. Their BB30 and PF30 press fits thread together to stop the creaks common with press fit BBs, and the BB92 uses dual-row bearings.

The bottom bracket is the bike part you only think about when it starts creaking. Don't be that guy in your group, fit one of these so the loudest thing on trail is your riding style.

Measure your BB shell width and check if it is threaded or press fit.
Match the spindle size to your cranks (30mm or 24mm).
The T47 BB is the external cup version, not T47 internal.
The 68mm road/gravel BB fits 68mm BSA shells with no spacers.
