Mavic Cosmic SL 45 700C wheelset, disc, Shimano HG
The Mavic Cosmic SL 45 Disc wheels with a widened 23mm UD carbon rim are the French brand's most versatile carbon wheels, while increasing comfort and performance.
They are equipped with Infinity hubs, which ensure efficient power transfer thanks to optimized contactless spoke lacing (no noise under load) and stress distribution. The front and rear spokes are the same length. Easy maintenance thanks to tool-free solution.
The cartridge bearings are double sealed, with an internal clearance of C3. The system automatically adjusts to ensure perfect, long-term rotation without any play.
Instead of drilling into the rim to anchor the spokes and fit the nipples, a threaded metal insert is integrated into the rim's lower bridge flange, allowing the spokes to be screwed directly into it. The bridge of the upper rim remains intact. A rim base is not required to ensure waterproofing.
The new Instant Drive 360 freewheel system is ultra-lightweight and efficient. The oversized, non-contact rubber seal reduces friction to a minimum and, thanks to a wide selection of adapters, is compatible with a wide range of frames and axles.
Features
- Improved aerodynamics: Less drag, more watts thanks to a 45mm rim profile and flat spokes developed by our aero experts and tested in the wind tunnel.
- Improved response: With INFINITY hubs, power transfer is extremely efficient, making the wheel even more responsive.
- Unrivaled versatility: The lightness of the 23mm rim and spokes make the Cosmic SL 45 Disc the most versatile Mavic road wheel ever designed.
