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.
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.
