Bike Rumor posted up a long term review of Mavic’s Crossmax ST wheelset. They seem to have been really pleased with their performance and durability. In my experience I’ve been happy with Mavic’s wheelset offerings in recent years. They may not be the lightest or have a crazy amount of engagement but they do have some light weight rims (equaling less rotational weight – faster acceleration, deceleration, and climbing) and hold up well to punishment.
“The Crossmax STs sit in the pleasant position of being not too anything. Neither too light nor too heavy, too wide nor to narrow, too cheap nor too dear. As an all-around “one wheel” for XC/trail riders, they’re pretty much ideal.” – Bike Rumor
