Frequently Asked Questions
Are 45mm carbon rim brake wheels good for climbing and everyday road cycling?
Yes, the Bola EXP 45C's 1280g weight places it among the lightest 45mm rim brake wheels available, providing a balance between aerodynamics and climbing efficiency for all-around road use.
How does a 1280g tubeless carbon wheelset compare to other lightweight options?
Many carbon road wheelsets in this depth category exceed 1350g. Bola EXP 45C’s sub-1300g build enables faster acceleration and reduced rotational inertia, matching or exceeding peer offerings like Farsports and Light Bicycle.
Is a 25mm or 28mm external rim width better for wider road tires?
Both widths support modern 25–32mm tires. The 28mm option improves aerodynamic stability and comfort with larger tires; 25mm remains a preferred choice for 25–28mm tires. Choose based on tire size and desired ride feel.
What are the benefits of DT 240S hubs and Sapim CX Ray spokes on a wheelset?
DT Swiss 240S hubs are valued for reliability and easy servicing, with low rolling resistance. Sapim CX-Ray spokes provide aerodynamics and fatigue resistance, favored in premium handbuilt wheelsets.
Are basalt-coated rim brake surfaces effective in wet conditions?
Independent lab and user tests confirm basalt-coated tracks enhance braking modulation and fade resistance versus standard carbon, especially in wet weather—a critical factor for safety on descents.
Lightweight and Durable Construction
The Bola EXP 45C DT240S 45mm carbon road wheelset expertly balances weight and strength, weighing only 1280g.
