Stan's NoTubes Alpha 340 Pro Front Wheels

The Alpha 340 Pro offers tubeless technology in a classic ultralight road wheelset. Built around speed, durability, and serviceability, the Alpha 340 Pro is ready for competition at any level for a fraction of the cost of many competitors' wheelsets. Lighter by design, the lower profile sidewalls and lighter shape of Alpha rims allows them to accelerate faster and ascend like a true climbers' wheel. The Alpha also delivers superior control. Tubeless or used with tubes, the Alpha's rim shape to let your tire expand to its true volume to improved cornering in all conditions. Combining six pawls engaging in sets of three, the Alpha Pro’s Neo Ultimate hub features near instantaneous 5-degree engagement. Further machining of the Neo Ultimate's 100% CNC shell shaves additional weight. The Neo Ultimate hub includes larger bearings, and a stronger, stiffer, shoulderless axle that provides unmatched strength and reliability. Sapim's CX-Ray spokes are both light and exceptionally strong, while also being aerodynamic. When combined with specific Road Tubeless tires, the Alpha offers a ride normally only found with tubular tires and rims, but maintains the simplicity and low maintenance of a clincher.
