25mm Inner Wide Carbon Spoke Wheelset ARWS
Revolutionize Your Ride: The Ultimate Ultra-Light Carbon Spoke Wheelset
Engineered for riders who refuse to compromise between weight, stiffness, and aerodynamic efficiency. Featuring a modern 25mm internal rim width, ultra-light 4.0mm high-modulus carbon spokes, and the lightning-fast Serenade SR251C hub, this wheelset is crafted to transform your cycling performance—whether you are tackling vertical alpine climbs or crushing flat-out sprints.
1. The Power of Wide: 25mm Internal Rim Width
Modern cycling has evolved, and narrow rims are a thing of the past.
-
Optimized Tire Profile: The 25mm inner width allows wider tires (28mm–45mm) to sit square, eliminating the balloon/lightbulb effect.
-
Superior Traction & Cornering: Enjoy a larger contact patch for supreme grip on high-speed corners and descending turns.
-
Lower Rolling Resistance: Run lower tire pressures without sacrificing speed—delivering unprecedented comfort over harsh tarmac and gravel.
2. Carbon Spokes: Lighter, Stiffer, Faster
Say goodbye to steel spoke deflection. Built with 48 high-tensile carbon spokes, each weighing a featherlight 3.4 grams.
-
30% Greater Lateral Stiffness: Delivers instant power transfer the moment you stomp on the pedals. No flex, no lost energy.
-
Vibration Absorption: Carbon’s inherent material properties mute high-frequency road buzz, keeping your legs fresher for longer miles.
-
Straight-Pull T-Head Design: Ensures optimal tension distribution and long-term durability under heavy loads.
3. Heart of the Wheel: Serenade SR251C Hub System
At just 252g, the Serenade SR251C hub is a marvel of precision engineering:
-
Instant Engagement: Quick ratchet mechanism for zero-lag acceleration.
-
Smooth-Rolling Bearings: Ultra-low friction precision bearings keep you rolling faster for less effort.
-
Universal Drivetrain Support: Seamlessly swap freehubs between Shimano HG, SRAM XDR, and Shimano Micro Spline (MS).
4. Choose Your Perfect Depth & Weight Range (30mm – 65mm)
