Designed for aggressive XC use, Stan's ZTR Arch EX Wheelset loves technical trails. The "arch" rim shape is strong and stiff while keeping the weight low for a durable, responsive ride. Plus, the Arches are built up with Stan's 3.30 hubs and DT Swiss spokes to keep you rolling quick. And, this slick wheelset uses Stan's BST technology for easy tubeless conversions, while the rim's wide internal profile and lowered sidewalls boost tire volume for enhanced traction.

Stan's NoTubes BST design creates a tight tubeless seal between the rim wall and tire bead. The inner rim wall is the same size and shape as the tire bead. It's also shorter, which increases the volume of the tire.

The front wheel gets axle end caps for use with quick-release skewers (shown) and for 15mm through-axles. Installation is as easy as putting the ones you need on the axle.
