Frequently Asked Questions
Are 45mm deep carbon disc wheels good for both road and gravel riding?
Yes. The 45mm aero rim profile offers a versatile balance between speed and crosswind stability. The Bola SL 45R’s 28/30mm width supports both 28–32c road and gravel tires, making it suitable for pavement, mixed surfaces, or endurance routes.
What are the differences between 28mm and 30mm wide carbon wheelsets?
A 30mm external width gives enhanced lateral support and accommodates wider tires for better grip and comfort, especially in gravel or rough terrain, compared to classic 28mm wheels which prioritize aerodynamics for road.
Is a 1340g carbon wheelset strong enough for heavier riders?
The Bola SL 45R uses T800 carbon layup and is tested to ISO 4210-7 standards for safety and strength. While lightweight, its construction and Sapim CX-Ray spokes provide dependable stiffness for riders up to 110kg under normal use.
How does this compare to other DT Swiss 350s hub wheelsets?
With its 36T ratchet and tool-free engagement, the DT Swiss 350s hub matches proven reliability, easy maintenance, and broad service support—an industry benchmark versus house-brand or generic hubs. Bola adds premium carbon and a fully certified build at competitive pricing.
What tire widths work best for comfort and speed?
The rim profiles are optimized for 28–32c tubeless or clincher tires, giving a smooth ride, low rolling resistance, and secure tire bead fit—suitable for both high-speed road cycling and mixed-surface gravel use.
