The BBR Tuning Sprocket and Adapter Assembly is a durable aluminum unit that provides fast and easy installation. Unlike the traditional sprocket clamp assembly, the BBR Tuning Sprocket and Adapter Assembly ensures concentricity with the wheel hub by using the unique two piece adapter that wraps around the rear wheel hub and enables you to drive the entire wheel instead of applying pressure on the spokes.


Standard Large Adapter:

Fits any rear hub with a diameter of 1.52-1.528".
Used with 12G and 14G spokes. 

The following are compatible coaster brakes hubs:

  1. High Stop
  2. K Stop
  3. Falcon
  4. Bendix
  5. Micargi
  6. Shimano CB-110
  7. Shimano CB-110E
OCC Chopper Adapter:Specifications:

FWL/5, 6, 7 Speed Adapter:

NOTE: The BBR Tuning Sprocket and Adapter Assembly is only compatible with the 415 Heavy Duty Chain. BBR Tuning adapters are only compatible with BBR Tuning 5-Hole sprocket. 9-Hold Sprockets (like those what come with engine kits) will need heavy modification to fit with BBR Tuning adapters.
