Chromag Chain Ring Sequence Direct Mount Sram Boost Black

"These chain rings use the official X-SYNC technology licensed from SRAM for unmatched chain retention. The unique high-precision tooth profile creates a reliable single-ring setup that reduces the chances of dropped chains, while simplifying and lightening the bike by doing away with front derailleurs and chain devices. Each tooth has a longer, squarer tooth profile to engage the chain earlier and drive for longer. Every second tooth is wider and features a crosshead profile that is chamfered at the tip. To be offered for 104, 94 and 74 BCD cranks and a direct mount option for SRAM cranks. CNC machined in Whistler."
