    Having both the Mercury Wheels headquarters and some of the country's best trails just up the road from our offices is a convenient convergence of geography. It allows us to spend some time putting the X1 Carbon Enduro 27.5in Boost Wheelset through its paces on some pretty gnarly terrain. We can attest to the fact that these rims are stoutly stiff, in no small part due to the beefy Boost axle widths, which translates to snappy responsiveness on climbs and razor sharp tracking through root lattices and rock gardens.

    The rims are built with a hookless bead, which—almost counterintuitively—makes the rim-to-tire bead connection more reliable for tubeless setups. Burping and tire blow-offs are actually more common with hooked rims, and the hookless models demonstrate improved tire retention on-trail. By eliminating the ridge of material constituting the hook, hookless beads also enjoy increased structural integrity—a definite plus when you consider that the X1 Carbon is built for the rigors of enduro violence. We have found that mounting some tire brands can be a little tricky, but once they're on, the bead holds a tubeless setup as confidently as any other manufacturer's.

    • A carbon wheelset built to handle all-mountain abuse
    • Hookless bead provides confident tubeless seal
    • Spoke count balances stiffness and weight
    • Boost axle width for responsive pedaling and braking
    • Includes tubeless tape and valves
    • Item #MCW000M

    Disappointing, But Still Hopeful

    • Familiarity: I've put it through the wringer

    Purchased a set of these wheels at the beginning of 2019. After about 6 months of riding, I broke my first spoke. I am currently on my 5th failed spoke on the rear wheel alone. I ride a lot (and don't enjoy crashing, so I tend to be on the conservative end of the spectrum), and have a garage full of bikes; this is my first experience (seriously) with repeated spoke failures on any wheel I have owned.
    Mercury customer support was amazingly helpful and is in the process of rebuilding the wheel; I can't say enough about their responsiveness.
    From other reviews, this sounds like possibly a problem with their spoke vendor back in 2018, but time will tell. I'll update when the rebuild hits the trail.

    Sweet Deal!!!

    • Familiarity: I've put it through the wringer

    I’ve had these wheels for 10 months and no issues at all. I went with these as I wanted a great price bullet proof and tough wheelset to bomb through some rock gardens and these didn’t disappoint. Can’t beat the price of these and they look good.

    What a deal!

    • Familiarity: I've put it through the wringer

    I’ve been riding these X1 for over a year and they are great. Nice and light and as tough as nails. Over 1900 miles and no issues. Very pleased with my purchase.

    Drastic Improvement

      I was on the fence between buying a new bike or upgrading my wheels. I decided to go with the wheels since my money tree in the back yard is taking a break this year.
      My riding has drastically improved along with my confidence in the ascending and descending game.

      Long Term Review

      • Familiarity: I've put it through the wringer

      I bought a set of these wheels last April. I can't say that I am impressed. I have ridden them for 1.5 years now and have had numerous problems. The Mercury branded hubs are not very good. The first rear hub I had was constantly slipping and would not engage. I had them replace the freehub I think twice before I sent the entire wheel back to get the hub replaced entirely. Overall Mercury was willing to work with me and took care of me as best they could. The rear hub has been much better since they replaced it but it is starting to act up little. Getting loud pings as it engages, very similar to what was happening before it stopped engaging previously. The big issue now is that I am constantly breaking spokes. I am finally to the point where I am paying someone to re-lace the entire thing. I am also going to ditch the Mercury hub for a much more reliable DT Swiss hub. I do ride a fair bit but I also have other bikes that I split time on so I was hoping they would have lasted me much longer. After they replaced the hub and rebuilt it for me I think I have around 600 miles before I started having issues again. Overall pretty disappointed with them over the long term.

      Hi Kyle -

      If your wheels still fall under warranty, why not give us a ring and give us the chance to square things away for you? It could be something simple that wouldn't require the purchase of a new hub. We're always happy to help!

      These wheels have been awesome! Have had them for about a year now and the bearings and spoke tension are as good as they were new. For the price, you wouldn't believe the quality but I honestly believe these wheels may be the best on the market.

      Great 27.5 wheelset!

      • Familiarity: I've put it through the wringer

      I've had these for 6 month and they're holding up great. Nice and light. Amazingly smooth and the hand built quality is unmatched. Huge fan of Mercury.

      Perfection at a great price!

      • Familiarity: I've put it through the wringer

      I have been riding these for the last 4 months on very rocky and technical trails with no problems. They stay straight and true. Great hand built quality.
