I put an X graphite watershed on my Roubaix this month as well. I have about 90 trainer miles on it and am pretty impressed as well. I thought my Specialized Toupe was pretty good but was running into some issues with it after 3,300 miles and decided to give this a shot. I will bring it down to AZ next week and put it on my bike down there and give it a good test. Can't wait to ride outside for a few days. Have a Merry Christmas!
