GEAR INDICATOR CHAIN
Genuine Sturmey Archer Gear Indicator Chain for Brompton. This clever chain screws inside the hub and when pulled actuates a gear change within the hub.
This model is used exclusively for the Alloy shell Sturmey Archer hub used on both 3-speed and 6-speed Brompton bikes. A common problem if the bike is dropped - these can get twisted and your gears will not shift smoothly. This is what you need to replace.

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.
