I wonder if the spam bot has any tips for fixing gears? One of the gears (#4 I think) just skips on my bike, such as:

Nominal gear = 3; actual gear = 3
Nominal gear change: 3>>4; actual gear remains at 3
Nominal gear change: 4>>5; actual gear change 3>>5

Same thing happens in reverse. It's irritating, and I can't take it into the bike shop overnight because I need it everyday (OK, well I could get the bus for two days or whatever, but I like using it everyday).
