Shockcraft stocks bearings for our own Monocrome Bottom Brackets, Enduro, Shimano HT2, Raceface X-Type, FSA MegaExo, Truvativ/SRAM ISIS, Token ISIS, BB30, Hope, Trek Madone and many more.  Check out our selection of bearings below.

Bearing Press Service

We offer a complete bearing press service for our Monocrome Bottom Brackets.  Simply send us bottom bracket cups and we will recondition them with the bearings of your choice.

CNC Storm Drains

Shockcraft CNC Storm Drains

Water is the biggest killer of external bottom brackets.  Shockcraft can CNC machine water drains into our Monocrome bottom bracket cups at purchase or during bearing replacement.  The CNC Storm Drains allow water and moisture to escape so the bearings stay dry.  This greatly increases bearing life and reduces maintenance requirements.

 

Monocrome Bottom Brackets

Monocrome Bottom BracketsShockcraft delivers its own Monocrome Bottom Brackets to fit Shimano HT2, Raceface X-type, FSA MegaExo, Truvativ/SRAM GXP and Shimano Road cranksets.  We have the widest range of bottom bracket options in the world; topped off by very competitive pricing.  All parts are available as spares.
