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

Sorry - this kit has been discontinued in kit form by Brompton - please contact us for details of the individual parts required (they are listed below and all still available)

This Brompton upgrade kit allowed 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 included everything you should need for the upgrade (excluding tools)

This upgrade kit contained:

  • 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 and the bottom bracket

Brompton wheel upgrade kit, Sram 3 Speed to Sturmey Archer 3 Spe

My SRAM hub finally gave up the Ghost (circa 14 years old!), so ordered one of these. Its a very straight forward swap really, all bits are included assuming your cable is in good condition. The old SRAM changer appears to work fine with it and installation from start to finish including swapping tyre over was under an hour. Noticeable difference in how smoothly the bike runs and gear change is nice and crisp. I would strongly recommend buying this kit as you need nothing else other than the tools to do the job. HOWEVER, if you are wantng this in under a week choose next day delivery, although Brilliant BIkes dispatched this on a Thursday by First Class mail it arrived the following Wednesday. What exactly is FIRST Class about that service Royal Mail? NOTHING... thats what!
