Mavic Ksyrium Pro WTS Wheelset
The Ksyrium Pro uses the same technology as the Ksyrium Pro SL, which has set new standards for modern wheel building. This wheel is equally at ease on fast rolling terrain or mountain courses, and for a couple of hours or an all-day adventure.The rim shape has been enlarged by 2mm. That might not sound much, but when combined with 25mm tyres it increases the air volume by 18%. This extra volume means you can lower the tyre pressure by 20 PSI while maintaining the same rolling resistance as with a narrower rim and tyre.
