Within the popular range of Mavic Ksyrium wheels are the Elite, SL, SL Premium, Equipe and SSC models which are road wheels available at affordable prices up to top competition level performance.
At the entry level is the Ksyrium Equipe which is a clincher and available in black and white, 2010 and 2011 versions.
Next comes the Mavic Ksyrium Elite mid range wheel and most versatile, whether for racing or training and for different riders with various cycling aims. You can use the wheel with Shimano or Campagnolo drivetrain components and its available in wheelsets, front, rear, silver and black versions.
It has stainless steel spokes with variable section to give some beneficial aerodynamic properties and Mavic's design for the Elite has removed the rim holes for strength, increased rigidity and the convenience of no rim tape requirement.
The Ksyrium Elite 2009 has had design attention paid to most parts to reduce weight while maintaining reliability.
The Mavic Ksyrium SL is a top level wheel derived from the well known ES model. It has a high level of Mavic wheel technology built in, including a carbon front hub, optimised rear disc and assymmetrical rear rim to help ridigity under drive conditions. Titanium is used in the SL Premium version to lighten the wheel still further and both versions are known for strength and reliability.
Results for Mavic Ksyrium Wheels and Wheelsets include the following models and versions:
For the Mavic Ksyrium SL, some key features change as follows: the weights are reduced to 660g on the front and 825g on the rear, using Maxtal rim material. It is ISM lightened with SUP welded joint and UB control braking surface. Spokes are alloy Zicral material, ultra profiled, straight pull with 18 radial on the front and 20 Isopulse laced spokes on the rear. Hub bodies are ultra light composite, with FTS-L integrated free wheel mechanism, with adjustable, removeable and sealed cartridge bearings.
In terms of problems, specific complaints or issues, nothing particular appears when you search the forums and reviews. This seems to apply to all the wheels in the Ksyrium range. There are a few instances of the rear hub failing, but this is more than likely to do with isolated faults or perhaps very heavy use, which is of course difficult to tell from individual reports.
Some people mention the significant price difference between the Elite and the SL, but others say its worth it as the increase in performance is not just to do with the weight reduction in the Ksyrium SL.
