Product Review

SRAM offers its Inner Chainring, ideal for both road and 'cross riding, in myriad sizes to humor our impulses and account for whatever a given race throws our way. This ring is stamped from 7075-T6 alloy, a string of numbers and letters that is really just a funny way to spell "gear that will last." It gets the SRAM/TruVativ machining and coining treatment for precise shifting and the alloy is strain-hardened for virtual invincibility. The SRAM Inner Chainring - Road is available in 110 or 130 millimeter BCD (Bolt Circle Diameter) with 34, 36, 38, 39, 42, or 46 teeth. Please note that this ring is only 10-speed compatible.
