^ SRAM X-Sync Chainring – 0 Degree Offset. Back when SRAM announced their 1x system, everyone knew that they must have solved a key problem that had traditionally plagued those systems: chain retention. With a front derailleur, how do you keep the chain from bouncing off the chainring, without resorting to heavy chainguards or keepers? It turns out the solution was surprisingly simple. X-Sync chainrings keep your chain firmly in place thanks to two different tooth profiles. Every other tooth is a traditionally shaped one, that alternates with a taller, square shaped tooth that grips the chain and keeps it in place, without sacrificing performance. It’s an ingeniously simple solution that saves weight, improves performance, and delivers ultimate reliability.
