Rockhopper- gear shift problem(shimano)
Hi, can anyone help me with my problem?
I have a Specialized Rockhopper, quite an old one, at least 8 yrs old, and the crank gear won't select anything other, than the smallest cog. The deraileur moves when the lever is depressed, but returns to its first position. I guess what I'm asking is how can it be adjusted to allow the movement to select either of the three cogs and stay where I want it..??
The name of the gears on the bike is, Shimano total intergration Exage 500 GX..???
Please excuse my 'Blondeness' when it comes to the correct terminology, but I'm new to cycling again and its been a very very long time, since I was a kid that used to ride every day..
