Brompton wheel upgrade kit, SRAM 3spd to Sturmey Archer 3spd

This Brompton upgrade kit allows you to convert your 3 speed Brompton with a Sachs (later called SRAM) 3 speed rear wheel to  Sturmey Archer / Brompton BSR (Brompton Standard Ratio) 3 speed rear wheel and includes all you should need for the upgrade (excluding tools).

This upgrade kit includes:

• Brompton BSR (Brompton Standard Ratio) rear wheel - 2013 double walled rim version
• Rim tape (yellow for the new 2013 wheel)
• Axle nuts and washers (they are different on Sturmey Archer to SRAM - so use only these new ones)
• Sprocket stack (let us know if you would like us to pre-fit it to the wheel) consisting of: Chain guard, Sprocket (13 tooth), Circlip
• Gear indicator chain
• Cable anchor
• Chain 

Please note: If you have an old 46T chainwheel and intend to use the included chain then you will also need to replace the front chainwheel with a 44 / 50 or 54 tooth one.
