KMC-X9E Sport 136L E-Bike 9 Speed Chain
This is not the standard KMC X Series chain. This chain is designed specifically for the extra torque and abuse a mid-drive motor can put on a drive train. It is rated to go 7,500km (4,660 miles). I don't know about you but I am lucky to get 800 miles on a standard X series chain. Check out these features:
- Double X Bridge Shape
- Super fast + smooth shifting.
- Stretch Proof Treatment
- High Torsion Resistance
- Mushroomed Riveting
- Outer Plate Chamfering
- Inner Plate Chamferring
- Highest Pin Power (450 kgf)
- Triple X Durability
- Unsurpassed durability.
- eBike Approved
- Better durability and higher pin power to stand up to the high torques of an eBike motor.
- 136 Links (so you don't need 2 chains with big sprockets)
