Sturmey Archer gear indicator chain Mk II

As used on the current (as at 2018) Brompton BSR - Brompton Standard Ratio and BWR - Brompton Wide Ratio wheels

This chain pulls the internal hub gear to actuate a gear change (don't pedal as you change hub gears)

Suitable for Sturmey Archer / Brompton alloy shell hubs

This has a longer axle than the MK I - but you won't be able to compare unless you have both

We have added a picture with approx size to help you measure the axle length (we make it approx 65.5mm from the tip of the the screw - into the axle - to the end of the knuckle on the first link of the chain)

Compatible hubs include:

Brompton Sturmey Archer BWR - Brompton Wide Ratio
Brompton Sturmey Archer BSR - Brompton Sturmey Archer

This can be identified by SA II carved into the the spindle (you will need to remove the indicator chain to check what yours says) - you will also need to remove the dirt covering the marking on your existing indicator chain

We made this short video showing where the gear indicator chain fits and connects to the gear cable via the cable anchor, and how to adjust the hub gears

    my indicator chain has broken off with the poited screew end still in the hub. is there away to renmove this in order to fit a new indicator chain? Answer:
    This can definitely be removed - worst case is to disassemble the hub - any good bike shop should be able to do it - or you could bring it to us in Chobham
