DEORE XT Wheel Sets are offered in designs to suit your riding style: all-around XC disc brake performance, and new beefy All-Mountain design. All models feature UST Tubeless compatibility with improved spoking patterns and proven XT hub internals.
Strengths: light, got them a good price, easy to set up as tubeless
Weaknesses: not terribly strong for an "all mountain wheelset," garbage rear hub, narrow rims, only available with center lock hubs, proprietary spokes are difficult to replace when you break one, should have a 10 mm rear thru axle.
I got a great deal on these and bought them hoping they'd make a durable everyday wheelset. Well that wasn't the case. The rear free hub lasted about 2 months before it broke and Shimano wouldn't replace it under warranty claiming it broke due to abuse. The rear wheel was also knocked out of true after just a couple months of riding. I'll also throw in that the 6 bolt rotor adapters I bought from Shimano fit the hubs poorly. The rotors would wiggle back and forth under hard braking. For a high end wheelset, these things are garbage.
