I just bought an '08 Specialized Tricross Sport Triple. Its spec-ed out with Specialized forged alloy hubs and Alex Ace-19 rims. I'm thinking these aren't the greatest setup - but I'm not sure. I'd like to upgrade to someting lighter. I'm not planning on doing any CXing - the bike is for commuting and wet road training rides. What wheel sets would be a nice upgrade? Hopefully, I can keep it under $400-$500 bucks. Also do CX bikes have just beefier road wheels or is the dropout spacing wider and therfore its like a tall skinny mt bike setup?
