evo.com | SRAM Chains > SL might stand for 'Super Light,' but don't be fooled, the SRAM XX SL Eagle Transmission 12-Speed Chain is a heavy lifter. Constructed with superlight plates and a cut out design, it slashes weight while employing SRAM's signature Eagle Flattop design for maximum shifting performance at any speed. Not suitable for E-MTBs. Super-Light Outer Plates with Cut-Out Design Chain Connector PowerLock 12s T-Type BLK PVD Hard Chrome(TM) The SRAM HARD CHROME(TM) chain has four times the elongation (wear) resistance to other SRAM chains. This is due to the new finishing process on the inner links and rollers. Push pin strength and ultimate strength are equivalent to current chains. The HARD CHROME(TM) chain lasts longer and is just as strong. Chain Length 126 Links Flattop To get a narrower chain, SRAM designed this unique profile that is quieter, stronger, and more durable than traditional shapes. | SRAM XX SL Eagle Transmission 12-Speed Chain 2025 - 126 Links in Silver
