For those of us looking to up our cyclocross game, transitioning from clinchers to tubeless can make a world of difference in speed, handling, and overall effectiveness out on the course. With Stan's NoTubes' impeccable reputation for building race-ready wheels boasting industry-leading tubeless design, the ZTR Iron Cross Pro Disc Wheelset is the ticket to the next level. Built specifically for cyclocross, these wheels clock in as the lightest of the Iron Cross line and are ready to throw down with the best to challenge for the win.

Despite being the lightest wheels in the line-up, the Iron Cross Pros utilize the same Bead Socket Technology (BST) found throughout the Iron Cross series, which features low profile sidewalls that provide a better seat for the tire bead and allow for a heap of benefits compared to standard rims with higher sidewalls. When setup as tubeless, BST provides an exceptional seal while allowing the tire to hold a greater volume of air than standard rims, which place the bead 2-4mm below the edge. This interface lets the tire maintain its full shape for a wider, more stable rolling platform than if the same tire were mounted on a standard rim.

When BST is paired with the ability to run up to 30% lower air pressure than a standard clincher, the results are exceptional tire stability, better handling, solid cornering, and better overall control out on the course. These rims are also compatible with standard tubes, with the lower sidewall drastically reducing pinch flat risk by reducing the amount of material present for the tube to pinch against. This means less time running to the pit with a flat and more time battling for position out on the course.

Stan's laces the Iron Cross Pro rims to its own 24-hole 3.30Ti hub up front and a 28-hole 3.30RDTi hub in the rear, both of which upgrade the standard, chromoly NoTubes' bearings to smooth-spinning stainless steel cartridge bearings that glide on lightweight 7075 Alloy axles. The rear hub body boasts beefy 58mm flanges, while the driveside houses a hardened, 30-point engagement ring. At the front, a similarly beefy 58mm disc-side flange manages braking force while a 45mm flange on the non-disc side balances strength and weight. The freehub is compatible with SRAM and Shimano 11-speed cassettes.

The Stan's NoTubes ZTR Iron Cross Pro Disc Wheelset comes complete with Stan's yellow rim tape and 35mm Red Alloy valves already installed for tubeless use - just add your favorite tubeless-ready tire, sealant, and air to get race-ready in a cinch. Please note that the ZTR ZTR Iron Cross Pro Disc Wheelset has a maximum tire pressure of 45 PSI and a maximum recommended rider weight of 170lbs.
