rhsno21482113wrote a review of Mercury Wheels Enduro Alloy 29in Boost Wheelset - OE on July 31, 2019
Familiarity: I've put it through the wringer
I didn't review too quickly, I wanted to see how well they worked. First, aired up tubless (Maxxis tires) w/o any effort. I always use a compressor, it's easier, but I would bet these seat easily with a floor pump. They seated much easier than the OEM rims.
Ride is fine, I don't notice any flex. A few hundred miles and still true. I know I got these for a special price (couldn't resist) but pleasantly surprised.
A minor issue, the spacers don't stay in so when removing the wheels what out for the spacers. At times the drop off.
UPDATE - After three months of riding the rear wheel is out of true and at least one spoke is really loose. I need to look closer, it may be broken. I wouldn't expect these issues after only three months of use. Spokes are smaller than OEM so this could be contributing to the failure. Closer inspection and the rim is severely bent. I have to change my rating, I haven't had an issue with other rims so durability is questionable.
