I'm looking to purchace a new wheelset for my Trek 5000, but I some advice on what to get. I need something that can handle racing and training rides because I don't have enough funds to buy 2 sets at this time. I was looking at the Ksyrium SL's, but someone showed me the neuvations. THey seem too good to be true with that price, i don't know though. My selects that came with the bike are no good. THe front wheel creaks like it's its job, and the back wheel has a flat spot that happened in a crash in a race. I'd appreciate any input. Thanks
