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. 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!!
Black anodized finish with a machined brake track for consistent braking performance.
Fully tubeless compatible with 2 layers of 21mm yellow tape and 44mm valve stem.
Note: The 18 hole and 20 hole Alpha 400 rims are not recommended for use as a rear wheel and will not be covered under warranty when used as a rear wheel.
