North Shore Billet Variable Tooth Chainring 28T x 94mm BCD SRAM X01 Cranks

North Shore Billet Variable Tooth Chainring: 28T x 94mm BCD for SRAM X01 Cranks. The NSB Variable Tooth Chainrings uses a ΓÇÿThin-ThickΓÇÖ variable tooth thickness mated with a standard chainring tooth profile to help retain the chain on the front ring during all types of riding. By increasing the tooth thickness on half of the ringΓÇÖs teeth the chain is given less room to move and virtually eliminates chain drop when running a single front chainring.

Variable tooth profiling ensures ultimate chain retention
