Wheels look great on my Niner Jet 9 RDO. Light, strong and responsive. I shaved considerable weight from the original wheels that came on the bike without compromise. The psychological effects of a light, quality bike are immeasurable and inexplicable...you just gotta get it. LOL The wheels are well manufactured. They were straight and true out of the box. Spokes were perfectly taut. Parts are genuine. The carbon is strong and of high quality. I just slapped them on and took off. The customer service was very good, keeping me up to date on production and shipping...and you can' beat the price. I've ridden them a few times on challenging downhill single track with some pretty gnarly features. So far so good. But like anything, time will tell. I am very happy with my purchase so far!
