I bought this so that I can ride my 11 Speed while I'm having a rear wheel rebuilt. Rode 60 miles today, Mt. Diablo South Gate, descend North Gate, Reliez Valley with 4400 feet of climbing. Very responsive wheelset. Handles great on the descents. Easy to install Continental Gatorskin Hardshells and Granprix 4000's 25 mm The wheelset is heavy, but rolls nicely.
