ENDURO. ALL-MOUNTAIN....Call it whatever you like, at RideFast, we simply call it Mountain Biking and it has been our passion for over 25 years. This is the wheel that started it all. We build HOTLINEs for our terrain and the way we ride! Featuring UN1™ Carbon construction, they are light enough to help you climb to the top, while their Right Wide™30mm internal width, and Str8 Wall™tubeless-ready sidewalls provide the strength, stiffness, traction, and durability you demand for shredding the descents. HOTLINES are laced around our all-new US-built SPM straight-pull boost hubs. The asymmetrical design places extra strength where it's needed- near the brake rotor in front and near the freehub body in the back. The SPM rear hub combines an oversized aluminum rear axle with an indestructable, yet beautifully crafted, titanium freehub body, and delivers ultra-fast 5 degree pedal engagement. Each wheelset ships ready-to-ride tubeless, including RideLock™ tubeless rim tape and lightweight alloy valve stems. Wheelsets also include 3 additional spokes for those times when your “chances” rise up and bite you in the middle of a ride. Like all of our wheels, HOTLINEs are Handbuilt in California and backed by a 2 year warranty and a lifetime crash replacement policy. Take your riding to the next level, ride the HOTLINE!
