Long story short but my rear mech stopped going to four easiest gears, SRAM would not warranty it as I had removed anodised finish due to not liking the scuffs after a crash.
Anyway I took the mech apart and opened the motor etc, fixed the small gears and got it to cycle through 1-12. I'm now at the stage of installing the parallelogram spring and my god it's a mare.
I have tried for hours and hours, has anyone any experience, please in the name of god help me as I nearly had it then it uncoiled lol
