When i set the rear mech up, it shifts fine initially at the bottom of the cassette, but seems to get out of sync as it moves up the block towards 1st gear.
The rear mech will be in 1st and the shifter still click as if it's got another gear to go, but it doesn't appear to move and doesn't over shift (limit screws are set correctly at both ends)
it's like the shifter clicks 10 times for the 11 positions, but the rear mech is skipping up a gear somewhere along its travels.
I suspect it's a bent mech hanger? the rear mech was working fine when i removed it from the previous bike it was on.
I've just rebuilt one of my bikes with Chorus.

Any help appreciated!
