Developed using nano-loaded epoxy resin with high modulus carbon fiber, the Black Inc 28|33 wheelset is handcrafted to provide the ultimate performance regardless of terrain. The bead hook rim width is optimized for modern 28mm tubeless tires while the dual profiles pair low weight with best-in-class aerodynamics.Offering an aero performance that belies its lightweight, the Black Inc 28|33 wheelset has been designed to be the perfect pair of racing wheels for all types of topographies. Lightweight enough to climb with ease, aero enough to slice through the wind at a wide range of yaw angles, and durable enough to handle rough roads as well as smooth tarmac, these wheels complement all styles of road riding.Weighing just 1118 grams for the pair, the 28|33 rate among the lightest tubeless ready wheels to feature a bead hook design. Black Inc engineers have achieved this by using a nano-loaded epoxy resin with high modulus carbon fiber to reduce weight while ensuring rigidity. An offset spoke bed balances the spoke tension to increase wheel strength. The deeper rear profile paired with the slightly shallower front wheel optimizes aero performance as well as crosswind stability Designed specifically for modern tubeless 28 mm tires, the Black Inc 28|33 wheelset match high performance with reliability.Specifications:- Spokes: 24 Inc Aero Carbon Spokes Straight Pull- Spoke Pattern: 2x/2x- Nipples: Inc Oversize Internal Alloy Type- Versions: Shimano / XDR / Campagnolo- Weights: Shimano: 1118g (Front: 491g, Rear: 627g)- Compatibility: Shimano HG 10/11 speed cassette, SRAM 10/11 speed cassette, SRAM 12 speed cassette, Campagnolo 11/12 speed cassette- Hub: Front: HU-07 Alloy Body / Rear: HU-07 Alloy Body- Hub Width: Front: 100mm / Rear: 142mm- Axle type: 12mm Thru Axle- Bearings: Black Inc + CeramicSpeed- Brake interface: Center Lock- ASTM Classification: Level 1- Material: High Modulus Carbon Fiber (T-700/ T-800)- Finish: UD matte glossy clearcoat- Type interface: Tubeless and Clincher (inner tube)- Type compatibility: Tubeless / Tubeless Ready / Clincher- Recommended tyre size: 700c x 28mm- Rim height: Front: 28mm / Rear: 33mm- Rim width: Internal: 23mm / External: 28.5mm- Decals: High Polish Laser Etch- Types: Tubeless / Tubeless-ready / Clincher- Assembly: The 28|33 wheels are hand built by artisanal wheel builders and inspected with the latest electronic machines.
