This month SRAM released details of its new Force CX2 group, a single-chainring cyclocross racing parts kit that reportedly borrows technology from its single-chainring mountain bike groups. Force CX1 uses SRAM’s X-Sync chainring technology, which uses alternating wide- and narrow-teeth to improve chain retention. The chainring design is combined with a rear derailleur with a roller bearing clutch, X-Sync pulleys and other technologies to improve chain retention. The parts will be available July 1.
