THIRTY FOUR Disc Wheelset

The Black Inc THIRTY FOUR is a high-performance carbon gravel wheelset designed to balance the strength needed for off-road durability with a weight light enough for competitive road racing. Optimized for modern wide tires, these wheels feature a hookless rim profile that enhances aerodynamics and simplifies tubeless setup.

• Optimized Gravel Profile: Features a 34mm rim depth and a wide 25mm internal width, providing excellent support and stability for tires ranging from 32mm to 43mm.
• Hookless Rim Design: The hookless bead is designed to make seating tubeless tires easier—often requiring only a floor pump—and creates a smoother aerodynamic transition to the tire sidewall.
• Premium Bearings: Comes standard with CeramicSpeed bearings in the hubs, offering exceptionally low rolling resistance and long-term durability in dusty gravel conditions.
• Lightweight Strength: Built with high-modulus carbon fiber to remain responsive on climbs while maintaining a Level 2 ASTM classification for reliable performance on mixed terrain.
• Refined Ride Quality: The 24-spoke construction is engineered to absorb road buzz and vibrations, delivering a plush and compliant feel on hardpack gravel.
