With SRAM's X1 Chain, it's 1x11 all the time, so the chain can be narrower, stronger, faster -- all because it doesn't have to deal with high-stress, front chainring shifting.

Since it only has to do rear shifts, gear changes are telepathically fast and feathery light. Its "wide tooth, narrow tooth" pattern perfectly matches SRAM's X-Sync chainrings so dropped chains and cumbersome chainguides are a distant memory.

The durability is impressive, too, with SRAM's Hard Chrome tech, solid pins and a proprietary link finish for improved life span.
