Sram Force unlocks the effortless simplicity & ultimate versatility of AXS wireless technology for a wider audience than ever before. More progressive X-Range gearing across a greater variety of groupset configurations exposes the true capability of any bike & allows the rider to ride faster, farther, & easier. Beyond just an incremental improvement over 11-speed chains. Sram X-Range gearing technology centers around the development of 12-speed cassettes & the 10-tooth smallest sprocket. For the chain to operate over an increased range of speeds Sram had to redesign it, it is narrower than previous chains yet the gap between the chain & the teeth of the drivetrain has actually increased to reduce noise. This has been made possible through the engineering of Flattop technology, the outer flat surface of the chain increases strength & durability allowing for a narrower design. This chain is designed to work harmoniously with Sram X-Sync chaining technology to help retain a deflected chain even over rough terrain.
