Hey, thanks for opening the thread. I'm a noob and just purchased a new bike that came with a Shimano Alivio front deralleur (update 3-5) and SRAM SX4 back derailleur and shifters.
It worked fine the first day I took it out, but now when I pedal really hard the front chain slips down a gear- sometimes even slipping off the whole bike! Also, it is really hard to shift the front gear up, causing a nasty grinding sound for a while. I just bought a book on maintaining and repairing bikes, but havnen't had to the time read yet (last semester of grad school.)
I will take it into my LBS, but what do you guys think the problem is? (I am a total noob and don't know how to adjust anything.)
