I have been riding a set of Xero wheels for 2 years on my Giant, I have had no issues with these wheels. I am building a Flyte SRS-3 up, most likely with Shimano Ultegra. I would like to spend $300-400 on a wheelset. I am 240lbs, but let's assume that my weight will be 190-210lbs.(I am 6'4) by the time my build is done in the spring of '07, I have lost 50lbs since winter. What wheelset should I buy, I have had my eyes on Mavic Ksyrium Equipes or FSA400,if I can get my price. I would not mind another set of Xero's, but I would love to here some other ideas from roadies with build experience. I have lots of hours on a bike, but too few learning about components. Thank you, your 2 cents are priceless!
