DERAILLEUR CABLE ANCHORAGE & SPRING SET
Replacement Brompton DR Cable Anchorage & Spring Set. This is fitted to all 2-speed and 6-speed bikes and mounts on the chainstay under your chain. Its purpose is to pull the derailleur back down to the lower position when you change gear.
There are two types available, Pre-2017 for the older shifters found on bikes made anytime in and before 2016, and New-2017 for Brompton's new integrated shifters found on all new Brompton bikes made after 2017.
The spring can lose tension over time or get clogged up, and it is worth replacing every few years when doing a cable replacement to ensure smooth shifting. Also, if you are upgrading an older Brompton to the newer integrated shifters, then this will need changing.

Brompton is the only company we've seen that answers all three criteria - and believe us, we've tried every brand out there. The reason others can't compete is because Brompton has answered a fundamental engineering problem. If a bike is going to unfold to a large footprint (which takes the twitch out) then it is unfolding to a bigger bike - and by all logic, a bigger bike unfolded would be a bigger bike folded. So, it's pretty much true that for most folding bikes they either have great rideability but poor transportability or vice versa. And nearly all of them are a mess to fold.
Not Brompton. Brompton has designed the Platonic form of all folding bikes. The bike folds to the smallest size on the market, unfolds in a highly precise and easy manner, and has the same axle-to-axle footprint as a hybrid bike. How did they do this? By not only designing a clever frame, but also designing some 1200 proprietary parts that make everything fit - and fit perfectly. Oh, and nearly all of this is made in England. No wonder this bike has a cult following.
