Going tubeless allows you to run low tire pressure for better traction while drastically reducing the chances of a flat. Stan's Standard Tubeless Kit converts standard tubed wheels to tubeless so you can reap the benefits. Everything you need to go tubeless is included. Plus, you won't miss dealing with flat tires and you'll save money on tubes!

Zipp makes the impossible possible with their 303 Firecrest Carbon Disc Brake wheels—they're equally at home on the flats as they are in the mountains. The 45mm-deep rims slice through the wind more efficiently than even many deep-section wheels thanks to their 28.5mm-wide dimpled rims. And, by creating a seamless junction between rim and tire, the increased width further reduces drag. The 303s climb with the best and re-accelerate out of corners like rockets since they barely register on the scale, which makes them a must-have on undulating terrain. The extra wide rim also allows running wider tires at lower pressures with less fear of pinch flatting, which boosts ride quality and comfort and reduces rolling resistance. Plus, Zipp's 77D/177D disc hubs gives you incredible stopping power in wet and dry conditions alike, and they're thru-axle compatible (sold separately) for jaw-dropping steering precision and power transfer. You also get Sapim's oustanding CX-Ray spokes.

Lay down Stan's Universal Kit Rim Tape before the tubeless conversion of your non-Stan's rims. It makes your rims air tight and ready for tubeless use by covering the spoke holes.
