I just bought my brand new 2005 Specialized Allez about a week ago because i'm looking into getting into roadbiking. However whenever i shift using the front gears, it doesn't work (usually shifting up from smallest gear (granny) to the middle gear). Usually i get a weird cranking noise and every once in a while my chain will come off completely and I have to put it back on manually. I have only been able to shift once or twice succesfully using the front gears.... any suggestions? should i just bring it to the bike shop and have them fix it? or is there something i can do on my own that will fix the problem?
Any quick responses would be greatly appreciated!
