Aluminium chainring with 44 teeth

The 130 mm Narrow Wide chainring for the Bafang BBSHD with 44 teeth and changeable chainrings. The engine is less stressed by the higher RPM and at the same time saves a lot of weight. The spider is in aluminium, the chainring in steel

Superb for mountainous regions where the original chainring of the Bafang with 46 teeth is too large. The chainline is a bit more outside than the standard steel ring, because of the screws. See also the PDF in the download below.

It offers an offset inwards of 10.5 mm, ideal when the swingarm is too wide and the chainring is grinding on it. Optionally, the chainring can also be moved inwards by a few millimeter with spacers and longer chainring screws. Also a different chainring with 130 mm 5 arm can be mounted. Chainrings are available from e.g. Gebhardt Classic with 38 to 66 teeth. Alternatively, an additional chainring or chain guard can also be attached to the outside.

The weight is about 368 grams (42T) and saves more than 200 grams of weight to the standard steel chainring.
The inner hole has a diameter of about 41 mm, the bolt circle of the chainring bolts has about 52 mm.
