X3 Enduro 27.5in Boost Wheelset

Hand-built in Utah, the enduro-specific but all-mountain loving Mercury X3 Enduro 27.5in Boost Wheelset strikes the sweet spot as a do-it-all wheelset. It's relatively lightweight at 1754 grams, reliably sturdy, and stiff with boost spacing, but without the premium cost of carbon hoops. And a 30-millimeter internal width optimally supports tires from 2.2 up to 2.8 inches in width.

Mercury laser welds the X3 Enduro to ensure a consistent, seamless rim that's well-balanced and without irregularities. The pronounced bead socket and flat rim bed allow you to set up tubeless tires without excessive effort easily. Mercury uses Axis-CL hubs from the X1 line and sealed cartridge bearings for longevity, even in sloppy conditions. 28 Sapim Race double-butted, spokes, and Sapim brass nipples ensure a reliable, durable wheelset without the excessive weight of burlier wheels with 32 spokes. The X3 does not come with tubeless tape or valves, but is tubeless compatible.

  • Nimble alloy wheelset for enduro and all-mountain sessions
  • Boost spacing for modern sleds and improved stiffness
  • Respectably lightweight for easier maneuvering
  • Alloy for a performance wheel without the carbon price
  • Axis-CL hub trickles over from the X1

I've put it through the wringer

Bought these wheels 4 months ago to replace my OE wheels. This is my second set of Mercury wheels I have purchased, one set for road and now MTB. The quality and attention to detail is incredible with these wheels. Plus the look great. Two thumbs up.

Great wheelset and price!

These X3 wheels really work well. The 30mm inner width is perfect for stability and fast cornering. These wheels are light and extremely durable. The hub is excellent and the engagement is quick. Very well made wheels.

These new X3 wheels are a huge upgrade from my Stans wheels. They spin better, they're quieter with super fast engagement. Highly recommend these wheels.

The new X3 wheels are a big change from my Stans set. Lighter, wider and feel more responsive on the trails. Great hub engagement. Tubeless set up was very easy. Highly recommend.
