Standard BBSHD 42T Chainring
with changeable 130mm BCD Adapter
- This is our standard Bafang BBSHD Chainring with 42 narrow wide teeth which includes a changeable 130mm Bolt Circle Diameter (BCD) Adapter.
- Using this chainring, the engine is less stressed by the higher RPM and at the same time saves a lot of weight. The chainring in steel, but the adapter is in aluminium.
- Superb for mountainous regions where the original chainring with 46 teeth is too large.
- It offers an offset when the swingarm is too wide and the chainring is grinding on it. The chainring can also be moved inwards by a few millimetres with spacers and longer chainring screws.
- Different 130mm chainring adapters with 5 arms can also be mounted.
- The weight is about 368 grams and saves more than 200 grams to the standard steel chainring.
- The inner hole diameter is about 41mm, the bolt circle of the chainring bolts is about 52mm.
- For BBSHD motors only. Not suitable for BBS01 or BBS02.
