The Evolve DH BB uses the massive M12 spindle and is intended for riders that want maximum strength.

All Evolve Series BB's feature slide on cartridge bearings with full ball construction. These are lighter, stiffer and feature a higher load carrying capacity than the typical one-piece cartridge bearings. And with twice as many balls per bearing as the competitors, these bottom brackets spin smoother and last longer. To further enhance performance Race Face uses their own proprietary grease formula. This increases the bearing life up to four times.

Features 

• CNC machined, heat treated, hollow M12 chromoly spindle.
• Shot peened finish for strength.
• Forged & CNC’d aluminum cups & reinforcing sleeve.
• 118mm spindle & offset drive side cup for use with chain guides. 
• Single row, double sealed cartridge bearings.
• High-pressure contact lip seal in conjunction with low friction labyrinth cup seal keeps out contaminants & increases bearing life.
• Newly improved extreme condition bearing grease.
• Features 2 bearings on drive side to accommodate higher drive train loads.
• Fixed cup spacer (2.5mm) allows BB to be used with either 68 or 73mm shells. 
• Proprietary non-side loading design.
