The Flattop technology of the SRAM Rival chain creates a lighter, quieter and stronger chain that is compatible with 1x and 2x AXS drives. Ride further, longer and faster: this chain does it. PowerLockSRAM's chain engineers developed PowerLock as a tool-free, secure and consistent way to connect chains. Although PL does not require any special tools for assembly, given the tight tolerance range of a 10- and 11-speed drivetrain, each PowerLock can only be used once. X-RangeRoad bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear. FlattopTo enable X-Range gearing technology, they developed a narrower chain. The unique link shape of Flattop technology not only allowed for a wider gear range, but also results in quieter drivetrain operation and increased chain strength and durability
