Nickel, reinforced. Reinforced inner and outer plates transfer torque produced by the e-drive loss-free. With 132 links, the chain can be adjusted with any required length.
NOTE: 7e8 chains will NOT WORK with derailleur-equipped bicycles. These chains are very heavy duty and strong, but because they have bushings (for extremely long wear life) they are not flexible enough to work with a derailleur.
If you need a chain for an older 7-speed bike with a derailleur, buy a 700, 7Z1 or 708 chain.
Compatible with all linear drive systems.
