The Lekkie 36-tooth converter is specially designed for Mid-Drives BBS-01 and BBS-02.
36 teeth greatly reduce maximum speed and increase drive torque and terrain permeability. The converter is suitable for off-road or slow driving with higher power requirements. A narrow and wide tooth structure is used on the chainring to eliminate chain derailment. The low weight of 86 g is achieved thanks to the heat-treated 7075 alloy material used. The converter is optimized for the best possible chain link. Reducing the chain shift can be solved using a spacer.
