BWR 3 speed sprocket set

Not available as a factory fit option, but this sprocket stack lets you use your BWR (normally used as a 6 speed) with just 3 speeds - with a bigger jump between gears than using the derailleur in combination.

This is a kit of parts for the BWR sprocket stack for fixing to the Brompton / Sturmey Archer wide range (BWR) rear hub and contains the following parts:

  • Plastic chain guard
  • 13 tooth rear sprocket (3.1 mm) - Shimano splines
  • sprocket spacers (2.0mm and 2.0mm)
  • circlip
  • Fitting diagram

This video from Brompton shows how to remove and re-install the sprocket set.

Brompton Q part code: QRSPRSTACK-BWR3
Brompton part number: 9024155 

(Note: if you are replacing the sprocket due to wear - we also recomend that you replace the chain)
