Stan's No Tubes Grail Comp Front
Details
Your bike can do more. Whether you're riding and racing on gravel, pavement, or between the tape at a cyclocross race, Grail wheels with Stan's patented BST-R tubeless technology offer less rolling resistance, more control, and the ability to seal most punctures almost instantly. Upgrade your bike to the leading tubeless rim design, and find out what you've been missing. The Grail's versatile BST-R rim design makes it compatible with tubeless road tires, low-pressure tubeless converted tires, and conventional tires and tubes, offering you total flexibility in a single wheelset. The Grail's wider shape improves both cornering and straight line tire stability. With triple freehub bearings, co-molded seals, and full CNC machined bodies, the Grail's Neo hubs are ready for big miles and whatever conditions you can throw at them.
Grail wheels come with yellow tape and 44mm tubeless valves installed. Front wheels ship with 15x100mm TA end caps installed, and also include 12x100mm TA and QR end caps and skewers.

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
