Frequently Asked Questions
Are 45mm carbon tubular wheelsets good for mountain climbs and flat racing?
Yes, the 45mm depth balances aerodynamic performance for flats and light weight (1220g/set), making it suitable for both climbing and speed on varied terrain. Tubular construction further reduces rotational mass.
What’s the difference between 25mm and 28mm wide carbon road wheelsets?
25mm external rims optimize aerodynamics with 25–28c tires, while 28mm width allows higher tire volume, lower pressures, and improved comfort with 28–30c tires. Riders should check fork/caliper clearance for wider setups.
How much do lightweight carbon road wheelsets improve speed and acceleration?
Switching to a 1220g carbon wheelset can yield up to 10% faster acceleration compared to 1500g+ alloy wheels, reducing inertia for climbs and sprints. Aerodynamic rims also decrease drag at 35–45km/h speeds.
Can I use these wheels with standard rim brakes and 28c tires?
Yes, this model is rim brake-specific, with a carbon braking surface compatible with most standard road calipers. 28c tubular tires fit the 25mm and 28mm rim options—always confirm frame clearance.
Is a 1220g carbon wheelset worth it for everyday training and racing?
This weight level provides responsive handling with durability for frequent use. Backed by a 2-year warranty and serviceable DT hubs, it's a practical upgrade for enthusiasts prioritizing value over brand premiums.
