The last 2 bikes I've owned I've noticed after riding them nice and hard for a year or so I end up having shifting problems. I can never get it adjusted to shift so that all gears won't jump, there is always 2 gears somewhere that it wants to jump in between. I'm fairly mechanically inclined and I've also had my LBS adjust it for me just to rule out me being a retard. The LBS also checked my hanger to see if it was bent and it's not.
Not really sure what's going on here. I just replaced my rear derailleur on my trek scratch 7 because my old one wasn't holding chain tension very well and had the shifting issue. Still have the shifting problem with the new derailleur, it's not as bad, but its still there. I did notice though that some of the teeth on the cassette have burrs probably from where the chain jumps while pedaling. Haven't sat down to file them down, but I would imagine it would help.
Also, I have snapped a chain or two far in the past by shifting whilst pedaling hard. Learned from that and now I shift and pedal as lightly as I can so that it hurts my drivetrain as little as possible.
Can the shifter itself go bad? It just seems like the 1:1 ratio that sram talks about isn't 1:1. It's more like 1:.90(not as perfect as when I bought my bike new).
My setup as of now is Sram X7 shifter pod, with an X9 in the back. Single 32 ring up front and 11/34 cassette.
Any ideas or suggestions would be greatly appreciated.
