SRAM Red D1 Flattop 12 Speed Chain

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. Features: Flattop technology enables a narrower chain with quieter operation and increased strength and durability. Hard Chrome plated inner link plates and rollers for reduced wear and prolonged life. HollowPin construction for increased strength and efficiency Requires new Flattop Powerlock
