Built for riders chasing speed without sacrificing durability, the NOX Skyline 275 is an ultra-light 27.5”/650B carbon rim designed for XC racing, lightweight trail riding, and performance-focused gravel builds.
At just 335g, the Skyline 275 combines low rotational weight with excellent lateral stiffness for quick acceleration and precise handling. Its asymmetric rim profile helps create a stronger, more balanced wheel build, while the 23mm internal width provides an ideal platform for tires ranging from fast gravel setups to XC mountain bike tires.
NOX’s RockGuard HL™ hookless bead reinforces one of the most impact-prone areas of the rim, helping protect against rock strikes and direct impacts. The Anti-Burp Bump™ improves tubeless tire retention and helps prevent burping at lower pressures, while UniWeave™ carbon construction balances strength, stiffness, and weight.
