The demands of cyclo-cross are unique to both road riding and mountain biking and, as a result, SRAM have introduced the world’s first cross-specific groupset. The SRAM Force CX1’s single- chaining takes centre stage, borrowing first technology developed for the firm’s xx1 off-road setup.
By removing the inner chainring, SRAM say cxi is lighter, simpler and more reliable than a double-ring wide setup, while still offering a gear selection suitable for cyclo-cross. The chaining adopts a wide-tooth, narrow-tooth profile designed to keep the chain in place and remove chainslap. The chainring is available with 38, 40, 42, 44 and 46 teeth and the corresponding ca comes in 11-25, 11-26, 11-28 and 11-32 sizes.
The rear derailleur, meanwhile, uses a roller bearing clutch to tug on the chain in order to keep it taut, again to keep the chain secure. SRAM Force CX1 is an 11-speed groupset but the rear mech is also compatible with existing ten-speed RAM road setups. Two shifters are available to work with either mechanical brakes or hydraulic disc brakes Disc brakes have been allowed in cyclo-cross races since 2010 and Force CX1 is available with SRAM’s hydraulic stoppers. All in all SRAM Force CX1 is designed to offer smooth shifting on any terrain and in all conditions -be it rain, mud, sand s or anything else the cyclo-cross Gods conspire to throw at you.
