My 8yr old bike which has Shimano Ultegra gears ( a year old) the frameset has now started to flex and creak ( not suprising I have beaten the hell out of it) so my son has offered his Battaglin as a replacement which has Campagnolo Centaur gears.( 6 years old but hardly used) The frameset is great, nice and stiff, however the gear change to a harder gear feels much harder than the ultegra and feels like there is a real drag on it within the lever. The change down with the little thumb lever to a easier gear tends to feel like a real clang. I have checked that the derailleur is moving freely and the cable slides through all the outers freely as well. It feels similar with the front derailleur lever. Seems to be the levers on both. My son says it has always been like that and is happy with it. I can of course just move the groupset off my old bike but I would like to keep it all Italian. I have never used campagnolo. So the question is, is there anyone with experience of both groupsets and does the Centaur just feel like this compared to the Ultegra? if so I can't put up with it, if not is there a common problem with the levers?
