Title says it all. My shifters are so bad, I can't believe how bad they are.
I have to push and push on the thing to make it change gears. I go to a different gear, and hear a bunch of rattling. I take the bike in for a tune-up, it shifts like crap. I leave the bike alone for six months, it shifts fine.

They're some kind of SRAM mountain bike, trigger shifters. Given the fact that the whole bike, a Specialized P series All Mountain bike, only costs $600 total, it may have just come with very cheap shifters.

That being said, I really don't need $300 shifters, that's unreasonable. What is a good mid-range priced shifter that shifts smoothly, and responds well?
