I swapped out the stock cranks and bb on a 2003 or 2004 giant warp, and put on shimano lx octalink cranks and bb. the chain was also swapped fro a sram 8 speed pc-58. I believe the old crank had a 42 big ring, and the new one has a 44 big ring. Now the font shifting throws the chain off. I tried to adjust, but have had no luck on it so far.
When I shift from 1 to 2, it goes from the granny to the big ring and skips the middle ring. When I go to 3, it throws the chain off. Is this an issue with the limit bolts, or the tightness of the cable? Do i have to bring the front dr up a bit? It is a low level 8 speed front dr, and 8 speed shifters.
I don't have my trusty bike mechanics manual with me, so I was hoping you guys could give me the basic info.
