You may wonder: "what is so special about a single speed chain?" Indeed, most manufacturers offer one model only. KMC disagrees. A chain for a Rohloff internal gear has totally different requirements compared to a chain fitted on a children's bike. That's why KMC has put a lot of effort into research- and development of these chains, solely for single speed or internal gear bikes.
Our B1 series come with:
- Bushing, for maximum rigidity
- Rust Buster coating (B1 RB) for great rust resistance
