I have just brought a second and Ciocc carbon road bike, very nice but it as a problem with the rear mech.

It's a campagnola chorus 10 speed. I need to take it off and get the barrel adjuster re taped. But how do you remove it?.
I have tried te shimano way 5mm Allen key but there s no Allen bolt in there. Not used to campagnola help please :?: ,SW Bike Mechanic is a mobile Bicycle workshop specialising in repairs and servicing for cycles in the Weston Super Mare and Somerset area
