Brompton chain with 100 links
Fits standard 6 speed Brompton (SRAM or Sturmey Archer BWR rear hub) - with 50T front chain ring.
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
Brompton Q part code: QCHAIN100DR
Brompton part number: 9022045
