SRAM PCEX1 10 Speed E-MTB ChainThis SRAM PC-EX1 10 Speed has been specifically designed for the extra demands that E-MTB bikes put on the chain. It is much wider and stronger than conventional chains and features chrome hardened solid pins and nickel-plated outer links for extra durability. It’s ideal for the high-torque and heavy duty use that it will encounter and is engineered to compliment SRAM’s E-bike EX1 groupset, for a smooth operation and efficient shifting.Features: 1x specific chain Solid pin construction PowerLock joining link Inner link finish: Polished Outer link finish: Nickel Pin Treatment: Chrome Hardened Recommended Group: EX1 Compatibility: 11-48 EX1 cassette Number of Links: 144Technologies: PowerLock - SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect our 10 speed chains.
