After researching, I've found that I can shave over 900 grams, over 2lbs, on race day by replacing my tank ass Bontrager Big Earl wheels with Easton Havocs and going with Super Tacky Minion front and High Roller rear. I'm assuming I'm going to get a bike that's easier to throw around the corners and a more lively suspension. Anyone else bounce back and forth between a heavy and light wheelset? Is it a night and day difference? I've never upgraded to a nice wheelset before.
