Brompton 98 link chain

Which Brompton is this chain for?

This chain is used on a standard 3 speed 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 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)

Brompton Q part code: QCHAIN098DR
Old Brompton Q part code: QCHAIN98DR
Brompton part number: 9022038

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 note:

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

Has lasted well

I have had about 6000 miles out of the previous chain and rear sprockets. I don't think that's too bad. I lubricate after each ride with Cleanride and i think that helps to prolong the life of the chain etc.. It certainly keeps the chain clean, which is useful if a rear puncture repair is needed.

Brilliant service from Brilliant Bikes.

Bought as part of a drive train replacement for my 2007 Brompton, the bike is running great now, awesome service from Brilliant Bikes.
Time will tell how long the chain lasts.

easy to apply

Easy to change. Lasts for a few months, which is why I don't give it 5*, though I believe that's typical of Bromptons. Service is great, very helpful and fast.

Brompton chain

The correct chain for my 6 speed Brompton. I do quite a high mileage and so end up replacing the chain quite frequently. As ever delivered at lightning speed by Brilliant Bikes. And as a bonus it was Brilliant Bikes' 24,000th order so they decided to refund my payment! Thanks a lot.

Asked by Andy
on 20/03/2021 Hello,I have a 5 speed (Sturmey Archer) Brompton circa early 2000, that I think is running a 1/8" 14 T rear sprocket and a 1/8" chain of 98 Links. The chain wheel is a single piece 50T.If I wanted to change the chain and sprocket can I fit a 3/32 SA rear sprocket and a 3/32" 98 Link chain or must replace like for like? Answer:
Yes your chain and sprocket suggestion would work fine.
