Bola ST 40T Carbon Road Wheelset - Designed for road cycling and endurance riding

The Bola ST 40T uses certified Toray T700/T800 unidirectional carbon to deliver consistent feel and predictable aero performance. Built with Sapim CX-Ray spokes and DT Swiss 350S hubs, the wheelset focuses on dependable engagement and easy servicing for riders upgrading from aluminum wheels or seeking a versatile race-train hybrid.

Why it fits your routine

• Balanced rim depth: 40mm profile offers aerodynamic benefit on flats and stability in rolling crosswinds while remaining manageable on climbs.
• Two width options: 25mm or 28mm internal rim width supports 25c–30c tubular tires so you can prioritize lower weight and aero efficiency or increased comfort and grip.
• Lightweight performance: 1200g ±20g per set reduces rotating mass to improve acceleration and climbing responsiveness.
