Bola ST 45C Carbon Road Wheelset 45mm Tubeless Rim Brake DT Swiss 350S 700C (1320g)

Climb with responsive acceleration and hold steady at speed on rolling terrain with the Bola ST 45C Carbon Road Wheelset. Built around a 45mm Toray T700/T800 rim and DT Swiss 350S hubs, this tubeless-ready pair delivers a practical blend of low weight and aerodynamic benefit for road riders upgrading from alloy or entry-level wheels. The machined carbon brake track and EN 14781 strength testing mean you get a modern carbon wheelset that fits rim-brake road bikes while supporting tubeless tires.

Bola ST 45C Carbon Road Wheelset - Designed for versatile road performance

The Bola ST 45C balances the demands of climbing, endurance rides and amateur racing by combining a mid-depth 45mm rim profile with a lightweight construction of approximately 1,320g per pair. Rims are laid with Toray T700/T800 unidirectional matte carbon fiber and are available with external widths of 25mm or 28mm and internal widths of 17mm or 21mm, allowing contemporary 25–30c tubeless or clincher tyres to be used for improved comfort and rolling efficiency. The wheelset is EN 14781 tested and rated for riders up to 100kg.

Comfort and control are preserved through a modern rim width that supports wider tyres, while Sapim CX-Ray stainless steel spokes and the reliable DT Swiss 350S hub platform provide predictable handling and serviceability. Tubeless readiness gives you the option to lower pressures for better traction and fewer pinch flats on long rides and rough surfaces compatible with the rim dimensions supplied.

Why it fits your routine

• Balanced climbing and aero performance: The 45mm rim depth offers a midpoint between lightweight responsiveness for climbs and aerodynamic gains on flats and descents.
• Lightweight construction: Approximately 1,320g per pair (±20g) reduces rotational mass to improve acceleration and reduce rider fatigue over long efforts.
• Quality hub and spokes: DT Swiss 350S hubs with quick-release compatibility and Shimano/SRAM 11-speed freehub interface paired with Sapim CX-Ray spokes for durability and reliable engagement.
• Tubeless ready: Compatible with 25–30c tubeless or clincher tires to enable lower pressures for added comfort and puncture resilience.
• Contemporary rim widths: Available in 25mm or 28mm external widths with 17mm or 21mm internal widths to support wider road tires and improved tyre profiles.
• Rim brake compatibility: Machined carbon braking surface engineered for consistent friction when used with carbon-specific brake pads.
• Safety and reliability: Designed and tested to EN 14781 standards and specified for riders up to 100kg.
• Value-oriented choice: Positioned as a factory-direct carbon option that compares favorably on weight and features to some premium competitors.
