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.
