- With its special Anti-Rust Coating, Connex 7Z1 is ideal for coastal areas with salty sea air, high humidity, and other extreme conditions.
- Suitable for 7-speed bikes with a derailleur.
- Snap-on connector included.
These chains are designed for use with internally geared hubs with a single 1/2 x 3/32 sprocket. They are very strong, but they're not flexible like a derailleur chain. For 6, 7, and 8-speed derailleur bikes, use Connex 8-speed chains.
