FYI the Easton Circuit couldn't handle my 220 lbs when I had them but I believe it was part bad build and part my climbing style (When I get out of the saddle I rock the bike prety good from side to side, I have been working to limit this). I paid to have the factory rebuild them and sold them in favor of a higher spoke count wheel. I highly suggest you look at 32 spoke 3X laced rear wheels. I got a set of DT Swiss RR1.1 rims laced to a hub by SpeedCific 28f 32r spokes and they have been bulletproof for the last 1200 miles. check them out at www.oddsandendos.com The prices are good too. Mavic Open pros are similar rims but weigh 10g more per rim and are a little more expensive. Velocity Aeroheads are another good rim choice as would be their Deep V rim. Lace any of these rims to the hubs of your choice (well have a wheel builder do it) and you will have a great set of wheels.
