Frequently Asked Questions
Are 45mm deep carbon tubular wheels good for club racing and hilly routes?
Yes. The 45mm rim depth offers a strong mix of aero drag reduction for flat segments and manageable sidewind handling, while the 1180g weight favors quick climbing and acceleration in hilly courses. Tubular construction further reduces total rotational mass—suitable for road events and hilly group rides.
How do DT Swiss 240S hubs compare to other road wheel hubs for performance?
DT Swiss 240S hubs are recognized for their low friction, high-precision machining, reliable ratchet mechanism, and tool-free maintenance. Compared to proprietary or budget hubs, 240S provides excellent durability with accessible service and upgrade options.
Is a 25mm or 28mm wide carbon wheelset better for wider tires and comfort?
Both options support a range of tires, but 28mm external width is optimized for 25–28mm tires and increases air volume for improved comfort and traction. Choose according to frame clearance and intended ride quality.
What are the benefits of a basalt-reinforced braking surface on carbon rims?
A basalt-reinforced brake track increases heat resistance, improves braking modulation, and decreases temperature-induced rim wear, especially on long descents—addressing a key concern for carbon rim brake wheels.
Are these carbon tubular wheels suitable for riders up to 100kg?
Yes. This wheelset is tested to EN 14781 standards and engineered to support riders up to 100kg when set up correctly and maintained within manufacturer guidelines.
