Brompton sprocket / disc set 13T for 3 speed BWR

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 BRW 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.
