Bola EXP 40C DT240S Carbon Road Wheelset — 40mm Rim Brake, Tubeless-Ready, 1300g

Imagine climbing a long, rolling ridge or finishing a fast group ride with noticeably less effort thanks to lighter rotational mass and balanced aerodynamics. The Bola EXP 40C DT240S is built for riders who want a cost-effective carbon upgrade that performs across climbs, endurance rides, and everyday road use while staying compatible with rim-brake frames and tubeless tires.

Bola EXP 40C DT240S — Designed for efficient climbing and all-round road performance

The neutral, matte UD carbon finish and 40mm rim depth create a refined presence on the bike while delivering functional gains: reduced weight for quicker accelerations, a mid-depth profile that helps on flats without compromising climbing ability, and a basalt-coated brake track tuned for reliable rim-brake stopping. These wheels pair well with 25mm or 28mm tubeless tires to improve comfort and puncture resistance on varied roads.

Why it fits your routine

• Lightweight and responsive: At approximately 1300g per pair (±20g), the wheelset lowers rotational mass for faster accelerations and easier climbing compared with typical alloy wheels.
• Balanced aerodynamics: 40mm mid-depth rims provide a compromise between aerodynamic efficiency on flats and manageable crosswind behavior for everyday road rides and group training.
• Durable rim build: Toray T700/T800 unidirectional carbon offers strength and stiffness in a matte finish that resists road wear.
• Brake performance: Basalt-coated braking surfaces are optimized for rim brakes to deliver consistent modulation and stopping power under varied conditions.
• Reliable hub system: DT Swiss 240S hubs are specified for low rolling resistance and long service intervals favored by endurance and race-focused riders.
• Quality spokes: Sapim CX-Ray stainless steel spokes offer high fatigue resistance, improved aerodynamics, and sustained wheel stiffness over time.
• Tubeless-ready versatility: Compatible with tubeless 25mm and 28mm tires to allow lower pressures for improved comfort, grip, and reduced puncture risk.
• Standards and safety: EN 14781 certification confirms international safety and performance standards; recommended rider weight up to 100kg.
• Compatibility: Designed for rim-brake bikes with standard 100x130mm quick-release spacing and for riders seeking a factory-direct value option with proven components.

Spec highlights include 40mm rim depth, external widths offered to suit 25mm or 28mm tires, internal rim widths that accommodate contemporary tire profiles, Sapim CX-Ray spokes for stiffness and durability, DT Swiss 240S hubs for smooth engagement and longevity, and a basalt-coated brake track optimized for rim braking. The wheelset is positioned as a performance-focused, value-oriented upgrade suitable for endurance rides, climbing-focused training, club racing, and bike builds where weight reduction and aerodynamic balance are priorities.
