What Our Gearhead(R) Experts Are Saying: "I've raced these in crits and fast group rides. The power transfer is instant, and they roll forever. The . 59deg hub engagement is no joke, and the 65mm depth holds speed without feeling sketchy in crosswinds. I'd recommend them to anyone chasing speed without compromise."When we want the fastest wheel on race day, we look to the Solix SL 65 Carbon Disc Wheelset. Industry Nine designed this setup to thrive on crit courses, fast breakaways, and any ride where speed isn't optional, it's expected. The 65mm carbon rim is wind-tunnel-tested and tuned for efficiency, helping us hold momentum through hard efforts and breakaways. At the center is the Solix SL hub, built with a 5-pawl system delivering an almost unbelievable . 59deg of engagement. That means faster accelerations out of corners, quicker responses in the pack, and less wasted effort. A 2:1 spoke lacing keeps the wheel stiff and balanced under load, while the tubeless-ready profile lets us run lower pressures for added grip and comfort. When the pace picks up, this is the wheelset we want beneath us.
