Bola CE 40R Carbon Disc Wheelset - Designed for road and gravel riding

The 28mm or 30mm external rim width was developed to optimize modern 28–32c tires, producing a stable tire profile that improves grip and comfort on mixed surfaces. At 1270g (excluding tape and valves), the wheelset reduces rotational mass for quicker accelerations and easier climbing while the 40mm rim depth maintains aerodynamic efficiency without excessive crosswind sensitivity.

Why it fits your routine

• Purpose-built rim geometry: 40mm depth with 28mm or 30mm external width and 21mm or 24mm internal width to support 28–32c tires and improved tire shape.
• High-grade construction: T800 UD matte carbon fiber rim for a balance of stiffness and measured compliance.
• Lightweight performance: 1270g wheelset weight (excluding tape/valves) suited to riders prioritizing climbing efficiency and responsive acceleration.
• Aerodynamic spokes: Foil carbon, straight-pull spokes—20 front (radial) and 24 rear (2-cross)—to reduce drag and rotational weight while enhancing lateral stiffness.
• Reliable engagement: DT Swiss OEM hub with 36T ratchet and Center Lock disc interface for quick, dependable power transfer on technical sections.
• Mounting versatility: Available for 12x100/12x142mm thru-axle or quick-release configurations and compatible with tubeless and clincher setups.
• Certified durability: ISO 4210-7 certification and REACH compliance for validated safety and material standards.

Real-world benefits include improved stability in crosswinds compared with deeper profiles, a rim width that enables modern tire volumes for better traction and comfort on rough roads and light gravel, and fast hub engagement for technical courses and group riding situations. The combination of a balanced rim depth, wide profile, and lightweight construction makes the Bola CE 40R a flexible upgrade for riders who need one wheelset to perform across varied terrain and race conditions.
