Stiffness. Tracking. Durability. Weight. It's everything you want from a wheel; the golden standard if you will. But is it actually obtainable? Is it really possible to acheive all of those things in a wheel without cutting corners somewhere? Specialized engineers say: yes. One thing that is incredible about Specialized is their approach to questions and problems as it relates to bikes. Things once thought impossible, they are making possible. Everything is a challenge to them, and they throw their small army of engineers at it and consistently get results. Take the bead hook on clincher wheels for example. All clinchers use it, except for Specialized. They figured out that their tubeless mountain wheelsets didn't need the bead hook, so they took it off. That is true innovation, something cycling desperately needs.
Specialized has managed to create awesome wheels that do hit the golden standard. Their Roval Control SL 29's are stiff in the corners and when you're mashing out of the saddle. They go where you tell them, tracking well over even the most rugged terrain. And even with those things, they still managed to make it a strong wheel that lasts. I've had two sets of these wheels and can't say enough good about them. There is nothing better than innovation. There is nothing better than Specialized.
