Necessary, if the chainring touches the bike frame
If the chainring teeth of your Bafang BBS01 or BBS02 motor run too close to the chainstay, this spacer will help. It is simply mounted between motor and chainring. This is perfect for moving the chainring to the outside without having to move the entire drive unit. It is possible to use 2 spacers - but longer chainring bolts should be used.
- 2 mm Spacer
- Fits for Bafang BBS01 and BBS02 motors
The inner hole has a diameter of about 50 mm, the bolt circle of the chainring bolts has about 60 mm.
