I have changed from a triple set up to a double, I have changed the front mech for a 2x10 and fitted new chain rings to lower and middle, bash guard to outer, new chain, cassette, shorter cage rear mech.

All works great but I can't get the front mech set up right it changes up to middle ok but when going back down to lower it always drops off onto the frame. I have tried the front mech in loads of positions, cable and index adjustment and end stop adjustment to no avail.

Do you have to get a double front shifter I'm sill on the triple one, or is it just the adjustment I'm not getting right?

Muchos help would be appreciated, thanks Colin.

    Just the adjustment you are not getting right.

    I have similar issues of losing the chain when I swap big to small on my 2x10 but only when I'm in the big sprocket on the back. I keep making adjustments and getting it closer, but it isn't quite right. Staying away from the big sprocket works ok until I get the adjustment spot on.
