Stupid Gears Setup

[ollietrex]

Is there some miracle art to getting gears to change properly?


After the pain of a cross threaded lock ring on my back cassette and a stripped bolt on my front crank I am starting to think just taking the bloody thing into the bike shop would have been easier.


I have a new back cassette and front chain ring and the back gears work fine but for the life of me I can setup the front gears to change smoothly. I can either get to to work correctly in the bottom two or nothing at all.


Any advice? I have followed the Zen Book Guide and still no help..

There's no real mystery to it. The Park Tool site goes through it pretty well:

Make sure to do everything in the order they specify.

try this


- detach the cable

- with your hand, make sure the derailleur moves up high enough to the big ring (loosen the low screw if not, half a revolution at a time)


- when the derailleur is without cable and at its lowest point, is it low enough for the granny ring?

(to get it lower, loosen the high screw, if its too low, tighten it)


If you're not changing the derailleur, putting it on the frame from scratch, or it hasn't taken an almighty knock in a crash, you shouldn't need to adjust the screws too much.


- If the above worked, and it moves to big and granny ring when you're moving it with your hand


- put the cable back on

- too tight and it won't stay in the granny ring

- too loose and it won't have the tension to the raise the derailleur to the big ring


the same can be done for the rear derailleur if its not shifting from 1st to 9th on the cassette.
