Any tips for a minor bike problem please.
I have my rear mech working crisply through the gears. Just one problem – when I go to shift the other way it takes 2 clicks before the gear changes. For example, when I shift through from the highest gear (small cog on the rear cassette) to the lowest gear, it indexes perfectly. When I go to switch back to the 2nd lowest gear the shifter clicks but the gear change dosent happen (the cable moves), then on the 2nd click it does go. It then will shift perfectly through to the highest gear, but as it is out of synch it jumps 2 gears when it gets back to the smallest cog again. The worst prob is when I am in say the middle of the gears and want to up 1 gear, then down 1 and so on, the problem means that any change in direction requires a 2-click shift.
What I’ve tried so far:
Cleaning and re-lubing the gear cable
Adjustment of gear cable
Checked alignment of rear mech (although I must confess its pretty difficult to tell the alignment between the rear jockeys and a 9-speed cassette)
Thanks in advance
