Just recently went out on my newly built Joe Young wheels – DT Swiss hubs w 32 hole Velocity A23 rims – attached to my 2014 Roubaix SL4 Sport SRAM disc. Now I’m not a seasoned roadie, but there is no comparison to the stock Axis 2.0 disc wheels. Joe’s wheel build is awesome. Buttery smooth and far more supple over the rough stuff. A lot of testimonials seem like nonsense, but no kidding on this one; being a bit out of shape and with my disc rubbing a bit (too lazy to readjust) I blew away my average time around my favorite riding loop without even trying! You will not be disappointed!
