Recommend me a new Cranckset and Cassette
Hello, I currently have a Campagnolo Centaur 53-39 cranckset with a 12-25 cassette. For some reason when I change to the disk with 25 teeth it starts rubbing up against the front derailer. Also if I try to change from my 53 disk to the 39 while on the 25 it does not hook on right, it stays floating on the top of the 39 disk. I have no idea exactly what the problem is. According to some people I have a bad configuration with that cassette. So I wanted to fist get a better cranckset and if the cassette configuration is incorrect also fix that. What do you guys think?
-Thanks

There is absolutely no reason a 53x39 and a 12-25 won't work perfectly together.
If the chain is rubbing on the front derailleur in the 53x25 combo, than that's normal. Don't use that gear. If it's rubbing in the 39x25 combo, then the limit screws of your derailleur need to be adjusted an eensie bit.
I don't know what you mean by "floating", but shifting from a 53x25 to a 39x25 is going to be difficult to get perfectly smooth; that's a major change in chain tension and chainline for the derailleurs to suddenly suck up. From your comments above (about the 39x25 rubbing on the FD), it's possible that adjusting the limit screws will give the FD just enough extra "push" to get it on?

Don't waste your money on new parts. Use the group the way it was designed to be used. Centaur works as well as Record for half the money. Good luck

Your rear derailleur needs adjustment. Check both the limit stops and the cable tension.
