Stans NoTubes Alpha ZTR 400 700c 18H Road Rim – Grey

Meet the ZTR Alpha 400, a rim that shares the same dimensions and patented Bead Socket Technology as the Alpha 340 but adds a triple-channel internal arch design that makes this rim nearly indestructible. The ZTR Alpha 400 also offers a 33% thicker spoke bed than the original Alpha 340 rim for maximum durability

When combined with 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 ultimate rim and wheelset for big miles.
