Hey all...
I have a GT Avalance 3.0. My problem is I'm ready to take the dive into FS but I want to keep a hard tale around. The problem is the GT skips gears like crazy. There is nothing like climbing a hill on a trail and feeling the gears slip out from under you. Mmm painfull grinding haults...All of my buddies keep telling me to change out the front/rear deraillure and crank. I've had the bike tuned 2 times aready at the LBS and they give me the "man why do you keep dumping money into this thing" look. SO...my question is....what is a good solid affordable front/rear deraillure and crank to get for a $300 hard tail. I'm looking at the HiFi for the next bike...probably the pro. Still waiting on the LBS to get a 17.5 in for me to test. Maybe the answer is to just ebay a hardtail? Ideas?

What's on the gem now you ask?
Shimano CS-HG3081 Sproket
Shimano Acera Rear Derailleur
Shimano Crank? SrSuntour Derailleur
