Flattop technology is so much more than a distinctive look. It allows SRAM's 12-speed chain to be lighter, stronger and more durable than anything that came before. The Apex chain uses the same construction as the Rival and Force chains, with a polished grey finish.
Technology
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.
