SRAM Red D1 Flattop Chain with Powerlock 12-speed 120 Links

The all-new SRAM RED chain was redeveloped from the ground up. The unique link shape allows the chain to be narrower and lighter while increasing strength and providing more space between the outer plates of the chain and the cogs on either side. Result: a quieter chain with faster, more precise shifts.

PowerLock
SRAM chain engineers developed PowerLock as a tool free, sure, and consistent way to connect our chains. While PL does not require special tools for install, the especially tight tolerances of 10- and 11-speed drivetrains mandate that each PowerLock is good for a one-time application only.

Flattop
To enable X-Range gearing technology, SRAM 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.

X-Range
Road 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.
