Boost Your Bracket With The SRX Cromoly

Bottom brackets are as diverse as they come. Depending on the material used they can be too heavy, too much bearing room or even super weak pedaling efficiency. To improve bottom bracket lightness, stiffness, and compatibility — meet the Race Face Evolve SRX CrMo Bottom Bracket. This nickel-plated spindle has the same 68 width shell but allows you to place the bearings further apart for ultra-efficient pedaling power.

This maintenance-free one-piece design features two full complement cartridge bearings, complete with labyrinth seals for a complete fit. The double lip wiper seals keep dirt out, while also compatible with E-type derailleurs or BB-mounted chain guides. The hollow CroMoly heat-treated spindle weighs in at a remarkable 245 grams, perfect for any genre of rides.

When it comes to the best in bicycle maintenance, make sure you are getting high-quality products without breaking the bank. The Race Face Evolve SRX CrMo Bottom Bracket is lighter, stiffer, and more effective for the ultimate in adventures to come.
