Hoogle Da Booglewrote a review of Mavic Ksyrium Elite WTS Wheelset - Clincher on July 18, 2015
Familiarity: I've put it through the wringer
Probably a great wheelset for the right body-types. If you are heavier than the average cat 2 racer and/or ride on anything other than glassy smooth tarmac, don't bother with these wheels. I rode a set of Equipes for a while and had pretty good luck with them so I decided to try the Elites. The rim on the rear cracked after 4 rides. Incredibly, I was still able to get home even with a fairly substantial wobble. See how they have machined away material in the rims? Well, sure that lightens them up but it also makes them more prone to breakage. My guess is that the cracking happened when I hit a divot in the tarmac on a downhill at about 30mph. I was riding out of the sun and into the shade so I didn't see the divot. Regardless, it' s the same kind of thing I've done, without issue, many times on the Equipes and on hand-built Open Pros-- i.e., it is not what I would call "unusual". I go about 195 lb so I sort of knew going in that these might not be the best wheels for me. Now, I know this with certainty. So, if you are larger and like pre-built alloy Mavics, stick with the Aksiums or the Equipes. They are heavier...but so are you. Otherwise, just get a set of properly constructed handbuilts with box section rims and at least 32 spokes.
