Incorrect shifting of a rear mech?
I'm hoping that somebody may be able to help me.
I had a new XT rear mech fitted today (Replacing a LX) by my local bike shop but it doesn't seem to shift correctly. When I pull the lever back the mech moves up to a bigger cog and when I push the lever away it moves to a smaller cog.
All the rear mechs I have used before work the other way (ie lever back and the chain moves to a smaller cog and lever forward the chain moves to a bigger cog).
Is this how the XT rear mechs are supposed to work?
Have the bike shop set it up incorrectly?
If so how would I go about changing it?
The reason I am asking is because, I am going away tomorrow and I won't have time to get back to my local shop.
Any help would be appreciated. Thanks
