hi guys, i have an early 90's bianchi 29er, that used to have a rusty busted old derailleur. i removed the front derailleur and extra chainring and shifter, and recently replaced the RD with a brand new shimano deore LX, new 8 spd cassette, and new chain. i also replaced the mtn drops with a pair of flat bars that came with my husband's jake the snake. the flat bars already had shimano STX RC shifters on them, of which i kept the right(rear) one.
all that said, i know how to adjust H/L screws and cable tension, but i can't for the life of me get the shift right. no matter what i do, i can't get the chain to run up past the 5th gear, rendering the lowest 3 gears unreachable. i've read sheldon brown's guide and there is nothing in there that i haven't already done. i'm getting really frustrated, and i need to ride my bike to work tomorrow. please help!
