I currently have the Bontrager race *** lite rims but have been considering selling them and picking up a set of the 2004 Ksyrium SL's. My problem with the carbon is that I am constantly worried about them. How are they packed in the car - are they going to get cracked? Is the glue going to hold, am I going to crash and ruin these wheels? I am a collegiate racer and just don't know whether the few hundred grams is worth the extra effort / concearn that running carbon rims pose. Any comments?
