For the price and weight, these wheels are hard to beat. I've been hammering on mine for 2 seasons. I've only broken 1 spoke due to a branch nub poking out of the trail. After I replaced the spoke, the rear wheel required minimal truing. I've done a variety of trail riding on these and have even taken my 429c on the dirt jumps up at the Canyons in Park City with no sign of fatigue. May not be the lightest wheelset out there but they are strong! I'm about 225 lbs and have barely done anything to them in regards to service. My only gripe is that replacement spokes can be tricky to source from an LBS.
