SRAM S7 Gear Adjustment Woes
Please help. I'm good with my hands and can usually figure things out, but the manual that came with the SRAM S7 is not answering all my questions. I have to properly adjust gears. I am failing thus far.
To put the SRAM S7 on a Swift I had to trim the shifter housing. This meant I had to trim the cable. I took the cable out of the clickbox but didn't think to notice how far the cable was wound around the little sprang wheel in the click box.
The manual says that the little etched line on the clickbox viewing window must align with the groove in the sprung clickbox wheel when changing from 4th to 5th. So I switched from 4th to 5th--then while on 5th--made sure there is alignment. Shifting worked poorly. I read on the Internet this adjustment should actually be made in 4th? Which is the truth? 4th or 5th?
What was happening is when I got to the lower gears the sprung wound up wheel was totally unsprung and the cable was loose. I then presumed I have to wind up the wheel half a rotation more so that the cable is always under tension. Is this true? How much cable should be wound on the little wound up wheel when the shifter is in 7th?
Thanks for you patience and kindest regards,
Jakub

The mark should be aligned in 4th gear. Reference page 62 of this manual for instructions:

If you want to make your job really easy, they make this special tool:

K6,
This is wonderful! Thanks a ton for the info. Now it's obvious to me SRAM published great technical documentation. It just wasn't part of the little pamphlet I received with my hub .
