I debated between the Mavic Ksyrium ES, Fulcrum R1, and the Eurus. My LBS didn't have the Eurus in stock for me to try. After much research I decided on the Fulcrum R1 wheelset. I am very pleased with it. I am 205 pounds and have no issues with wheel flex. I thought the wide bladed spokes would be hell to deal with in the wind but they are very stable in cross winds. I own several wheelsets but I always seem to choose the R1's for most rides. I also love the look of the R1's which was another deciding factor.
