Bola EXP 40R Carbon Disc Wheelset 700C — 40mm Deep, 28/30mm External, DT Swiss 240s, 1270g, Tubeless Ready

Imagine a wheelset that gives you confident speed on fast road efforts and predictable handling on rougher gravel stretches. The Bola EXP 40R Carbon Disc Wheelset pairs a 40mm-deep aero profile with a wide rim platform and lightweight construction so you can push hard on mixed-terrain rides without sacrificing climbing agility.

Bola EXP 40R Carbon Disc Wheelset - Designed for road racing and mixed-terrain performance

The 40mm rim depth strikes a balance between aerodynamic benefit and crosswind stability, while the broad 28mm or 30mm external profile supports modern 28–32c tubeless tires for lower pressures and improved comfort. Built from T800 UD matte carbon fiber around proven DT Swiss 240s hubs and Sapim CX-Ray spokes, the wheelset is engineered to deliver responsive acceleration, efficient power transfer, and durability for demanding use.

The combination of a 1270g package weight and a stiff, wide rim platform enhances climbing responsiveness and rolling speed, making these wheels suitable for competitive road events, performance gravel rides, and long endurance days where predictable handling and comfort matter.

Why it fits your routine

• Aerodynamic yet controllable: 40mm rim depth provides meaningful aerodynamic gain on flats while remaining manageable in crosswinds for mixed-condition riding.
• Modern tire support: 28mm or 30mm external width with 21mm or 24mm internal width is optimized for 28–32c tubeless or clincher tires, allowing lower pressures and better ride compliance on rough roads or gravel.
• Lightweight climbing performance: At 1270g (excluding tape and valves), the wheelset delivers strong acceleration and climbing capability comparable with leading lightweight competitors.
• Reliable hub platform: DT Swiss 240s hubs with a 36T ratchet system provide quick engagement, low rolling resistance, and durable performance under racing loads and variable weather.
• Quality build and materials: T800 UD matte carbon fiber construction, Sapim CX-Ray straight-pull spokes in a 24/24, 2-cross lacing pattern, and Center Lock rotor interface ensure a stiff and durable wheelset.
• Versatile fitment: 12x100mm front and 12x142mm rear thru-axle compatibility (also compatible with QR where specified) suits modern disc brake road and gravel frames.
• Standards and safety: Manufactured with a decade of experience under quality controls and compliant with ISO 4210-7 and REACH standards.
