Frequently Asked Questions

Are 40mm carbon road wheelsets good for climbing and endurance rides?

Yes. The 40mm depth and 1300g weight of the Bola EXP 40C enable an optimal balance for climbing and all-day endurance rides. Aerodynamic mid-depth aids on rolling terrain.

How does a 1300g carbon rim brake wheelset compare to alloy options for performance?

The Bola wheelset is lighter than most alloy rim brake wheelsets (typically 1500–1700g), resulting in faster acceleration and improved climbing efficiency.

Will a tubeless 25mm or 28mm wide wheelset fit my road bike with 100x130 QR axles?

This wheelset is compatible with 100x130mm QR frames. Confirm frame and brake caliper clearance for 25/28mm rim widths before installation.

What are the advantages of Sapim CX Ray spokes and DT 240S hubs?

CX Ray spokes minimize aerodynamic drag and are fatigue-resistant. DT 240S hubs provide smooth, reliable engagement and longevity.

Is a 40mm deep rim brake carbon wheelset suitable for heavier riders up to 100kg?

Yes. The Bola EXP 40C passes EN 14781 safety testing for riders up to 100kg. Adhere to tire and rim pressure limits for safe usage.
