The Bola PRO 40R wheelset combines a 40mm aero profile with 28mm or 30mm external rim widths and a sub-1200g pair weight to deliver a lively, efficient feel for endurance training, race preparation, and all-surface adventure. Precision ceramic bearings and flat carbon spokes sharpen acceleration and engagement while tubeless readiness improves comfort and grip on varied terrain.

Bola PRO 40R Carbon Disc Wheelset — Designed for road, gravel, and endurance use

From long weekend sorties to focused interval sessions and light gravel exploration, this wheelset emphasizes controlled speed and predictable handling. The wider rim options accommodate 28–32c tubeless tires for added lateral support and comfort, while the 40mm depth balances aerodynamic gain with crosswind stability for everyday riding and racing scenarios.

Why it fits your routine

• Lightweight performance: A claimed pair weight of 1170g (without tape/valves) makes climbing and repeated accelerations feel more responsive compared with heavier 40mm wheels.
• Aero and stability in one package: The 40mm rim depth provides aerodynamic benefit on flats and rolling terrain while the 28mm or 30mm external widths improve tire support and handling in crosswinds and on rough surfaces.
• Wider tire compatibility: 21mm or 24mm internal widths support 28–32c tubeless tires, enabling lower pressures for better traction and comfort on mixed surfaces.
• Premium construction: Toray T800 unidirectional (UD) matte carbon fiber delivers a high strength-to-weight ratio and ISO 4210-7 certification for safety and quality assurance.
• Efficient power transfer: Flat (foil) carbon spokes in a 20/20 straight-pull, 2-cross layout enhance lateral stiffness for direct pedaling response and predictable cornering.
• Smooth, fast engagement: Bola BL240 CNC aluminum hubs with sealed ceramic bearings and a 54-tooth ratchet system offer quicker engagement and reduced rolling resistance for spirited riding.
• Disc brake optimized: Center Lock rotor mounting and thru-axle compatibility (12x100mm front / 12x142mm rear) ensure reliable braking performance and secure wheel fitment on modern frames and forks.
• Tubeless ready: Designed for straightforward tubeless setup to lower ride pressures, reduce pinch-flat risk, and improve comfort across variable surfaces.
• Warranty and support: Comes with a 24-month limited global warranty that includes defect coverage and crash replacement support.

For riders upgrading a stock wheelset, preparing for amateur race events, or seeking a versatile pair for mixed-terrain adventures, the Bola PRO 40R delivers a balance of low mass, aerodynamic benefit, and modern rim widths that suit contemporary tire choices and riding styles.
