Olivier C.wrote a review of Mercury Wheels X3 Enduro 27.5in Boost Wheelset on December 12, 2018
Familiarity: I've used it once or twice and have initial impressions
These wheels are a great value! Perfect internal width for large tires. The most impressive thing to me was how easy they were to set up tubeless. I had read other reviews of earlier models being a bit of a pain. I taped up the rim using the supplied tape slipped on a Maxxis High Roller II and was able to seat the tire with a hand pump easily WITHOUT sealant!! The tire was pretty out of shape from storage so I left the tire on the rim for a bit to let it get its shape back. Then I released the air and added sealant and they havent lost any air over a few days, but even without sealant whey were holding air better than the previous wheels I had. Well done Mercury! At around $320 shipped there is no better deal for a full boost wheelset with XD driver. Trust me I looked. I'll update as I get more riding on them.
