Frequently Asked Questions
Are 40mm carbon tubular wheels good for both climbing and flat road races?
Yes, the Bola EXP 40T’s 40mm medium-depth profile provides a versatile balance of aerodynamics for flat terrain and a low weight (1170g) that performs well on climbs, ideal for all-around use in races and training.
What are the advantages of a 25mm vs 28mm external rim width for road cycling?
A 25mm rim maximizes aerodynamic efficiency with narrower tires, while the 28mm option supports wider tires for added comfort, grip, and improved ride quality on rougher roads.
How does a 1170g carbon wheelset with rim brakes compare to disc brake options?
This lightweight rim brake wheelset is generally lighter than most disc brake alternatives, offering responsive climbing benefits for riders using rim brake frames, but it is not compatible with disc-only bikes.
Is a mid-depth 40mm carbon tubular wheelset suitable for training and racing?
Yes, the Bola EXP 40T is engineered for both high-performance racing and regular training, balancing durability, stiffness, and all-around aerodynamic performance.
How durable is a basalt brake surface on carbon tubular rims for regular use?
The basalt-reinforced brake track enhances heat resistance and longevity compared to traditional carbon, designed for consistent rim brake performance across frequent rides.
