Brompton 102 link chain

102 links 1/2 inch x 3/32 inch with PowerLink - made for Brompton by SRAM

This chain is suitable for the following:

  • a standard 2 speed / C Line Urban Brompton bike (with a 54 tooth chainring)
  • an increased gearing 6 speed (BWR or Sachs/SRAM) / C Line Explore Brompton bike (with a 54 tooth chainring).

Note: if your chainring is smaller you would need to remove links (e.g. if changed from 54 to 50 you would remove two links and from 54 to 44 you would remove 4 links) 

Brompton chains are available in 4 different lengths:

  • 96 links - normally used on a 3 speed with reduced gearing
  • 98 links - normally used on a 3 speed with standard gearing
  • 100 links - normally used on a 6 speed with standard gearing (also for 3 speed with increased gearing or a 2 speed with reduced gearing)
  • 102 links - this one - normally used on a 2 speed with standard gearing (or a 6 speed with increased gearing)

Tools Required:

To remove your old (non quick link) chain and re-install this new one you will need a chain tool such as the CT-3 from Park Tool or equivalent
To remove an old chain which does have a quick link - a pair of chain link removal pliers can be very helpful
