Donald F.wrote a review of Mercury Wheels X3 Enduro 29in Wheelset on May 26, 2017
Familiarity: I've used it several times
The first thing you notice is that these wheels are solid. Not in a heavy way, but made from good material and well built.
I got mine built up with tubeless tires very easily and was off.
After several rides i am just in love with how they feel. They are significantly wider than the stock WTB i19s i was riding and I could tell a difference immediately. I'm not the best rider out there, so having a sturdy wheel that i don't have to baby is great.
All in all a very solid upgrade for someone who wants a wider rim without going to carbon.
