Harry Bidlemanwrote a review of Mavic Ksyrium SLR Wheel System on June 1, 2015
Mine are the 2014 model and unfortunately, the black exalith coating on the brake track has completely worn off so that they are a nice shinny aluminum now. Not the look I had hoped for when I bought them. Also, the little groves that are milled into the brake track have also smoothed with time so the sound and enhanced stopping has mostly disappered as well. Maybe they have addressed these issues with the 2015 models but it sounds like they worked on making them lighter and wider instead of more durable.
