Brompton 98 link chain

In 2025 Brompton have discontinued the 98 link chain - it is now only available in as 102 links, and requires cutting to size

If you would like to order the 102 link chain you can find it here

If you would like us to cut it to 98 links please leave us a message on the order and we will do so prior to shipping

We made an update video - below:

Chain compatibility:

This chain is used on

  • Standard 3 speed 16 inch wheel size Brompton folding bike (with 50 tooth front chain ring) with either the 13T or 14T rear sprocket
  • This chain is also used on a 2 speed or 6 speed 16 inch wheel Brompton folding bike with reduced gearing (44 tooth front chain ring) where the largest rear sprocket is 16 tooth (used on the two speed and BWR 6 speed wheels) or 15 tooth (as used on the old Sachs/SRAM 6 speed rear wheel)

The chain comes complete with SRAM PowerLink for easy chain joining

The table below shows all the chain ring / sprocket / chain combinations. Having the correct length is important - it will help stop the chain jumping off when folding (as the chain tensioner keeps it correctly taut)

If you are changing your chain we also recommend changing the sprocket(s) - changing just the chain will result in the chain wearing quicker and the chain may also slip on the old sprocket(s) when under load.

The chain is marked: SRAM PC-10

Tools Required:

To remove your old chain you could need a chain tool (it depends upon whether the old chain had a powerlink) - this will destructively remove all chains, or a pair of master link pliers (to remove the PowerLink to split the chain)

We made this short video to help choose the right size / length of chain, how to remove your existing chain and how to install a new chain on a Brompton folding bike

Historical notes:

2025 - Brompton discontinued the 98 link chain - making it available only as a 102 link chain requiring cutting

Originally the Brompton chains with 3/32" width were just for Bromptons fitted with a derailleur (hence the Q part code suffix of DR).

Later Brompton models (approx 2012 onwards) started using a stepped in rear sprocket on all models, regardless of whether it was a single rear sprocket or derailleur with double sprocket
