Ok I just converted my bike from ShimaNo to Campagnolo. I have built and tuned Shimano systems many times and never had an issue like this. Looking for some help here. Bike: Salsa LaRaza Components: 2005 Record Ergo levers, 2005 Centaur CT FD and short cage RD, Veloce 12-25 cassette, Wipperman 10SO chain (yes I know they say this is their Shimano 10s chain but with the difference being the width from the Campy chain it shouldn't be an issue as the new Campy Ultra chain is narrower).
So I had my chain off so that I could remove all the goo that comes on a new chain and put good lube on it. While it was off I went through the Campy directions for how to setup the shifting of the RD. #1 turn the pulley tension screw all the way clock wise. #2 with the cable tension loose set the outer limit screw with the upper pulley centered on the smallest cog of the cassette. #3 index up to the 4th cog (3 clicks on the shifter) and use the tension adjustment to center the upper pulley on the 4th cog. #4 shift to largest cog and set the inner limit screw and adjust the pulley tension screw if the upper pulley interferes with the large cog (it doesn't).
Ok so I did all that and with the chain off I indexed through the gears and it sure looks like it lines up right. Put the chain back on, lube it up and it shifts like crap. =/ Wont make the complete jump up to the next larger cog…if I push a bit more on the shifter (not to the next click) I can get it to go up and the down shift seems fine. If I add enough tension to the cable to get the up shifts smooth the down shifts aren't correct.
Got any thoughts?
