I wanted to change my derailleur cable on my 2017 6 speed and I was confused by this document.

The pdf tells me to disconnect the cable at the trigger end first. Then the procedure for removing the cable at the lower end sounded very complicated. In the end, it was simply a matter of unscrewing a 1.5mm hex grub screw at the lower end and pushing the cable out through a hole in the shifter, much like a conventional trigger shifter. If I had known that, I could have saved myself a lot of time.

It's hard to believe Brompton does such a poor job of providing technical documentation. There are glaring gaps and the documents that they do provide are not labelled according to model year.

I guess Brompton really wants you to go to their dealer for service. It's consistent with my frustrating efforts to try to buy a replacement axle for the Sturmey Archer hub.
