Looking for some advice - my s2l isn't shifting properly, won't go down to the smaller cog. I've replaced the cable, seems that's not the issue. The cable is moving at the connector end but the derailleur isn't turning, so I'm wondering if the spring could be the issue - any tips?
If it’s current shifter, probably the shifter playing up. Try bending the lever down towards the floor (they are surprisingly hardy so don’t worry about it snapping off), as if you’re trying to rip it off, often sorts it. Otherwise it’s to your local friendly Brompton dealer for a shifter warranty.
