Familiarity: I've put it through the wringer
With nearly 6k miles, I am very happy with my S5’s. I’m 200 pounds, along with road miles I ride some loose gravel, and they hold up well. The wheels remain true and show no signs of problems. The hubs roll smooth. At the sale price, I might get a set for my girlfriends bike. Very impressive for a great price. Nothing beats hand built wheels.
