Go anywhere with versatile, durable disc brake Grail rims and wheelsets tested extensively by Stan's cyclocross and pro road teams. The 24.5mm-wide design allows your tires to expand to full volume for drastically reduced rolling resistance and more control. Bead Socket Technology means you get ideal tubeless performance, putting the Grail in a class of its own for adventure, gravel, and road riding.

Tubeless Rim/Tire Cross-Section

Tubeless-ready rims are compatible with both standard and tubeless-ready tires. When a tubeless-ready tire is mounted on a tubeless-ready rim with special tubeless rim tape, valve, and sealant, the tire and rim form an airtight chamber that no longer requires a tube. This lets you run lower tire pressure with less fear of pinch flats and without the added weight of a tube. Lower tire pressure has many benefits, including greater traction and lower rolling resistance over rough surfaces. The rim can always be used with a tube, as well, by simply removing the tubeless valve stem and installing a standard tube like you would with any non-tubeless tire.
