Easton have designed their MTB wheels from the ground up for impressive lightweight performance. The rims and squat flange blocks that the 24 straight-pull spokes thread into certainly create a far stiffer wheel than you'd expect.
There's noticeably less flex under various loads than with most competitors. They've taken some large hits too, although replacement spokes will be hard to find if you do snap one.
Take-up speed on the three-pawl freehub is average, but the V-Max cartridge bearings are well sealed. Preload is self-adjusting, so you don't have to nip out any knock. The sculpted but short QR levers need a firm hand, though, and they're certainly not a cheap option.
