Meet the ZTR Alpha 400, a rim that shares the same dimensions and Bead Socket Technology as the Alpha 340 but adds the triple channel and internal arch design of our nearly invincible Arch EX and Flow EX rims. The ZTR Alpha 400 offers a 33% thicker spoke bed than the original Alpha 340 rim for maximum durability.

Combining six pawls engaging in sets of three, the Alpha 400 Pro's Neo Ultimate hub features near instantaneous 5-degree engagement. Further machining of the Neo Ultimate's 100% CNC machined shell shaves additional weight. Neo 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.  Light and fast on the outside, ultra-stiff and strong on the inside, the new ZTR Alpha 400 is the rim you've all been waiting for.
