Ever since a frame swap I've been having trouble dialing in my gears.

I have a Daytona 10 spd with only about 3500 miles on the cassette and 2000 on the Campy chain. The drivetrain is pretty noisy and occasionally doesn't want to go right into gear (more often at a slower cadence). In the stand I first adjust the rear limit screws, then tweak the tension with the barrel one way or the other to make it hit every gear. In the stand it shifts great -- right in. Still on rides it's causing issues.

On rides I've tried tweaking the barrel adjuster on the rear cable± 1/2 - 1 full turn and it seems like the tension is correct, yet I occasionally get the chain dropping down a gear (usually on a climb!) or not wanting to up... also before a climb.

I've cleaned the chain and use ProLink. When the shop installed the Campy chain, I don't know for certain if they reused the Campy links or not but I don't see and stiff links. I don't know that they work on many Campy groupos (none in the shop... and very few high end road bikes), but for my frame swap its who Cannondale said to go to.

Thanks

Good thought. The levers have about 3500 miles of use (7yrs... I know, hey, I didn't ride the bike the first 4 yrs!). I've never done anything to them (as far as lube goes).

Update: I put the bike on the stand and shot some lube on the springs. I reset the rear limits (actually they were good as-is) and tested everything. As before all the gears lock in fine. BUT I did notice I don' always get a strong CLICK when shifting up to a larger cog. Shifting 12 to 13 especially, then its hard to shift to 14 without it going up to 15.

Perhaps the chain is ramping up to the next cog, but the shifter is locking in correctly, thus allowing the chain to drop back down?? I'm going out for another test ride.

Thanks. I'll give that a try. I built the bike up myself and it ran great. I had a frame swap and haven't been happy with it since. You suggestion is good -- start from scratch.
