Bearing Press Service

We offer a complete bearing press service for external bottom brackets.  Simply send us your Shimano HT2, Raceface X-type or FSA MegaExo 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 your bottom bracket cups 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 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.
