I put my bike together and it was all great and fine. I took it for a spin and it would shift perfectly fine without a hitch but shifting the front deraileur up was a problem. I messed with the two little screws labeled H and L so much that the timing is really off. I'm going to put some lube on them and hope that I figure out which one is supposed to be placed how. The one labeled "H" is supposed to bring the deraileur higher right, so it could shift higher (closer to the outside)? Or should I just stop messing with it and bring it to a damn bike shop? Shifting from the small cog up to the larger cogs has become an issue, and at one point during my ride, my chain actually slipped off the smallest gear.
Any help would be appreciated. Diagrams, great explanations... anything in general would be great.
