i know my way around tuning up my newer road bikes. i can dial in 9sp da & 10sp campy very nicely, but my commuter bike is throwing me for a loop.
14 year old rigid mtn bike, with loads of miles. drivetrain is xt with 7 speed cassette. last year, i replaced chain & cassette. the shifter lines up the deraileur perfectly under each cog, but i can't ride in the 3 tall gears. i can shift through the 4 easy ones very buttery, but as soon as i get into the 3 harder ones..... it sounds & feels like it skips a tooth every time around (a slipping sensation). clunk! clunk! without a load, it shifts fine. but as soon as it has any load at all, it happens. why is it doing this, even when it's perfectly in-line with the cog?
it's not the hub, or else the easier gears would do it too?
thanks.....
