- Tested for riders up to 100kg; confirmed by EN 14781 standards – aligns with mainstream durability metrics.
Frequently Asked Questions
Are 45mm deep carbon tubular wheels good for club racing and hilly routes?
Yes, the Bola EXP 45T's 45mm depth provides balanced aerodynamics and stability, making it suitable for fast group rides and challenging elevation changes. The low weight aids in climbing while still offering aero benefits for flat and rolling terrain.
How do DT Swiss 240S hubs compare to other road wheel hubs for performance?
DT Swiss 240S hubs are known for precise ratchet engagement, low rolling resistance, and easy maintenance, matching performance and reliability with leading global brands in club and amateur racing.
Is a 25mm or 28mm wide carbon wheelset better for wider tires and comfort?
The 28mm option improves tire support for widths above 28mm, enhancing comfort and stability, especially for rougher roads or heavier riders. The 25mm width suits traditional race tires (23–25mm) focusing on speed and aero efficiency.
What are the benefits of a basalt-reinforced braking surface on carbon rims?
Basalt reinforcement in the braking track increases heat resistance, reducing the risk of overheating and prolonging rim life on descents or long braking periods – a verified benefit in lab and field testing.
Are these carbon tubular wheels suitable for riders up to 100kg?
Yes, the wheelset is EN 14781 certified for use by riders up to 100kg, aligning with international safety standards for carbon wheels in this category.
