Real-World Scenarios & Known Tradeoffs
- Balanced for mountain climbs and fast flat racing: 45mm depth offers aero performance with manageable crosswind stability (vs deeper rims).
- Tubular-only construction reduces rotational mass for climbing, but is less convenient for roadside puncture repairs compared to clincher/tubeless systems.
- 25mm width optimizes aerodynamics with 25–28c tires; 28mm width improves comfort and grip for 28–30c setups, subject to bike frame and brake clearance.
- Rim brake carbon wheels require more careful brake pad selection/maintenance than disc brake models and can have reduced braking in prolonged wet descents.
- DT Swiss 350S hubs prioritize reliable engagement and easy servicing – not as light as ceramic bearing hubs, but favored for long-term durability.

Frequently Asked Questions
Are 45mm carbon tubular wheelsets good for mountain climbs and flat racing?
Yes, a 45mm carbon tubular wheelset like the Bola ST 45T is engineered to balance climbing responsiveness and aerodynamic efficiency, making it well-suited for both mountainous terrain and fast flat riding compared to shallower or deeper rim profiles.
What’s the difference between 25mm and 28mm wide carbon road wheelsets?
25mm width typically maximizes aero efficiency for 25–28c tires, while 28mm supports higher volume 28–30c tires, increasing comfort and grip but requires frame/brake clearance. Both widths on the Bola ST 45T are EN 14781 certified.
How much do lightweight carbon road wheelsets improve speed and acceleration?
The 1220g weight (excluding accessories) and low rotational mass of the Bola ST 45T accelerate quickly on climbs and sprints, typically translating to measurable time savings, especially over hilly courses versus alloy or heavier carbon wheels.
Can I use these wheels with standard rim brakes and 28c tires?
Yes, the Bola ST 45T is compatible with standard rim brake calipers and supports 25–30c tubular tires. Confirm your bike's fork and brake arch can accommodate 28c tire widths for proper clearance.
Is a 1220g carbon wheelset worth it for everyday training and racing?
For riders who prioritize a lightweight feel and fast acceleration in both racing and fast group riding, the Bola ST 45T offers notable benefits. Tubular setups require pre-ride tire checks and glue maintenance—less convenient than clincher/tubeless systems for daily commuting.
