HERRMANS® FUSE 38T consists of two separate parts, the chain ring, and the chain cover tail. These two parts combined and fused together form a single entity. As separate parts, the modularity and customizability awaken! Fuse is made of recycled ABS plastic, which has a 90% lower carbon footprint compared to virgin ABS (raw material carbon footprint: 0.27 kg CO2-eq). Still with the same quality, characteristics, and style you would expect from Herrmans Bike Components. Snap-in front-fitting model with a modular design to make adaptation to different sizes easier. Fast snap on front fitting assembly with no visible screws for standard bikes and e-bike systems such as Bosch, Shimano, Yamaha and Bafang There is also a big number of rear fitting options.
