Ok, feel stupid on my first post but here it goes... I just recently bought a Haro Escape with some SRAM SX-4 shifters, well the thumb shifter on the right on kept bashing my thumb and bruising it. Went too far over the grip. The lever had a screw on the bottom of it and I thought what the hell, loosen it and adjust it to where it wont hit my thumb. Well, the lever pops off I was unable to put it back on. Well I think what the hell these things can't be too difficult so I take off the brake and grip to rip the whole shifter off to take it apart, WRONG, damn thing flew apart so fast I couldn't find out where the hell the gears went in it. Is it possible to even rebuild it? I have attempted it but not too much. Is it worth fooling with or should I take it to my bike shop to have it replaced with some shifters (possibly better shifters, suggestions?).
