Brand new, never installed on any bike

Power Drive BB Interface (not included)

Crank Bolts included

Bolted chainring, i.e. you can replace them. Better than Suntour or Shimano rivet systems, if something happens you will need to throw away the whole crankset, not with this product. You can also tweak the chainring configuration easily if needed.

Very rare and hard to find, they are no longer produced.
