"They’ve eliminated virtually any chance for anything to wobble, lean, tilt or otherwise introduce slop to the system. They're some of the smoothest wheels I’ve spun in recent memory. Sometimes, when things roll so smooth, there’s a bit of play at the axle, but there’s absolutely none here." BikeRumor.com - Read full reviews here and here.
"Regarding the ride quality, the CC40 managed to hit the sweet spot for my weight (~75kg), such that the wheels felt firm and robust without ever being harsh. As for the lateral stiffness, I never noticed any brake rub, and when fitted to a bike with barely enough clearance at the chainstays for the 27mm wide tyres, the paintwork remained scuff-free."

"The overall ride quality was one of the best I have experienced and it wasn’t accomplished by sacrificing stiffness." Fit Nation Magazine - Read the full review here.
"Smarter, not harder. That is the impression these hubs left on me." Kogel Bearings
"The wheels were everything Bobby claimed. More responsive, less lateral flex and faster than the Zipps" Bethel Cycle

"Right away, at the start of my first interval I was amazed at how well the wheels moved underneath me. Every watt was being transferred to the wheels. They just didn’t want to stop rolling. The team at Alto Cycling have really innovated the best wheel on the market." Adam O'Connor - Professional Triathlete
