Details
The Black Inc Thirty AR is more than just a climbing wheel. It accelerates like no other wheel due to its superb rim stiffness, wider rim profile, and perfect spoke tension.
Compared to other low profile wheels, the Thirty AR has a wider, CFD-optimized rim, making it more aerodynamic when used with 28mm tires. Most lightweight wheels on the market are simply not aero. This puts the Thirty AR in a category of its own: light AND aero. The Black Inc Thirty AR's shallow and wide rim design and vertical compliance also makes them suited for rough roads and cobbled races such as Paris-Roubaix or your favorite gravel loop. The Black Inc Thirty AR's tough construction is nearly bulletproof on harsh roads.
The Black Inc Thirty ARs revolve around the Black Inc + CeramicSpeed hubs, designed and manufactured around tight tolerances to take all the benefits of the silky smooth ceramic bearings.

- Enhanced durability for brutal road surfaces

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 beads. UST rims should be paired with UST-specific tires for best results.
