Brompton chain with 100 links (1/2" x 3/32") - and SRAM PowerLink
This chain fits a standard 6 speed Brompton (SRAM or Sturmey Archer BWR rear hub) - with 50T front chain ring - so standard gearing
This chain is for a 2 speed (12/16T with reduced gearing 50T front chain ring) or standard 6 speed (13/16T) Brompton bike (with a 50 tooth front chainring), or a 13T 3 speed with a 54 tooth front chainring.
Note: if your chainring is smaller you would need to remove links (e.g. if changed from 50 to 44 you would remove two links) - or purchase a QCHAIN098DR - 98 link chain
If your chainring is bigger your would need to add links (e.g. if changed from 50 to 54 teeth you would add two links - giving a chain length of 102 links) - or purchase a QCHAIN102DR - 102 link chain
Installing the new chain will be easier as it comes with a SRAM PowerLink
