Question about adjustments or similar. How do I measure(?) and adjust the knurled gear cable adjustment next to the hub so that all gears work properly.
Gears number 2 to 5 work fine. Number 5 gear has a slack cable compared to the other numbers. Gear number 1 for up the hill 1in10 slips out of gear. The cable is really tight.
This is manual for a 5 with brake, but the indicator adjustment is likely to be the same. Not too long ago, Sturmey had all the manuals posted on the net, but they've taken them down now. Sadly, this is just the sort of shoddy support that is typical of most component manufacturers these days.
You got to be very careful if you don't know where you're going, because you might not get there.
