Frequently Asked Questions
Are 50mm carbon tubular rim brake wheels suitable for both climbing and aero performance?
Yes. A 50mm rim depth balances aerodynamic benefits for speed while keeping overall weight (1230g ±20g per set) low enough for steep climbs. Tubular format further reduces rotational mass, aiding acceleration efficiency on rolling terrain.
How does a 1230g carbon wheelset compare to other lightweight road options?
This 1230g EN 14781-certified wheelset offers a competitive weight profile close to premium brands but at a more accessible price. Many higher-priced wheels in this segment exceed 1250g, especially when configured with similar hubs.
What’s the difference between 25mm and 28mm rim widths for road bikes?
25mm provides a classic aero profile optimized for narrower 25c–28c tubulars, reducing frontal area and crosswind drag. 28mm offers improved support and handling for 28c–30c tires, enhancing cornering stability, ride comfort and compliance on rough roads.
Is a basalt-reinforced carbon brake surface more predictable during braking?
Yes. Basalt fibers integrated within the carbon brake track improve heat dissipation, helping maintain consistent braking feel and prevent fade during prolonged descents compared to pure carbon-only tracks.
Which wheelset is recommended for club racing with 25c–30c tires?
The Bola EXP 50T suits club races where a blend of speed, weight and reliability matters most. It is specifically compatible with 25–30c tubular tires, fitting performance-oriented setups and EN 14781 regulations for amateur and intermediate racing formats.
