Stans No Tubes ZTR Alpha 400 Road Rim

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.


  • Can be run with tubes or tubeless.
  • For road and cyclocross
  • Bead Socket Technology (BST-R) for superior tubeless performance
  • Lightweight design for instant acceleration
  • Wide, low-profile rim design for better cornering and faster rolling
  • Compatible with road tubeless-specific clinchers and conventional clinchers when used with tubes
