LBS Makes a Bo Bo

[BSRU]

Got my bike back from the LBS last week, one of the things they did was to change the the rear derailleur gear cable.
On my first ride on it on Friday I noticed something very odd.
The right hand Shimano STI levers worked the opposite way to the way I expect.
The small lever moves the rear to a larger cog whereas the large lever moves the rear to a smaller cog.
I knew something was wrong but could not believe the LBS would make such a mistake or whether it is actually possible.
Confirmed my suspicions when I checked my road bike which works as expected.

Anyone know to put it right?
If it is a quick fix I will do it myself as taking it back to LBS is a right pain as their opening hours do not fit in with my work hours.

Not sure how this is actually possible, it suggests that the cable as been threaded in from the wrong side somehow

I'm with OFF how is this even possible?

+1 Surely not possible as the larger lever pulls the cable and the smaller unlocks the ratchet.
How strange.

What bike and rear mech?

Have they fitted a rapid rise?

I think on both my MTB and my road bike the big and small levers are set opposite to each other.

He's saying in the OP that they are STI levers.

I want to know how this is even possible.

Yes Shimano STI Tiagra levers on a Ridgeback Panorama with a Deore XT rear mech.

I am confused myself, I have checked several times to make sure it really is shifting the opposite way
Luckily my road bike shows me I am not going crazy.

That's what I find confusing, like others I can't see how it's doing it.

The xt rear mech is probably a rapid rise.

did you check you got given the same bike you took in?

 

[Peteaud]

So with the cable slack it is in the smallest gear?

ie the little lever has been clicked all the way.

My broken xt rear mech was replaced with a new one, the same version.

I will need to check.
