    Designed for the long haul.

    Bumpy gravel roads, light-duty singletrack, and tours across state lines call for a stout and supportive wheelset that's wide enough for running larger rubber, yet light and snappy when you're hammering up climbs and pedaling across miles of countryside. Designed for this very purpose, the Mercury G1 Carbon Disc Wheelset offers a superb balance of rolling efficiency, proven strength, and high-volume support for gravel exploration, bikepacking adventures, and long-distance tours.

    Sitting at a whopping 30-millimeters across (external width), the G1 Carbon Disc Wheelset supports higher volume tires in the neighborhood of 35 to 40-millimeters across, give or take a few millimeters for your riding preferences. Tubeless-ready rims allow you to drop the pressure of wider tires, in turn lending a smooth and supple sensation across rough roads and gravel surfaces. Ultimately, this means you'll conserve energy without the fatiguing feel of jarring bumps and excess vibration you've become accustomed to with gravel road exploration.

    Carbon construction maximizes stiffness, meaning you'll feel its snappy acceleration the instant you step on the gas. It's also stronger than its aluminum counterparts, ensuring longevity when you inevitably thrash 'em over jarring roads and unpaved surfaces. The G1 Carbon Disc Wheelset is designed for disc brakes and thru-axles, but is also adaptable to a front quick-release skewer, making it a great choice for a modern gravel world where no "standard" is ever really standard. Plus, its disc brake-compatibility means you won't have to worry about the loss in braking composure normally associated with a carbon road wheelset.

    Amazing Quality at a Great Price.

    • Familiarity: I've put it through the wringer

    Super happy with this carbon wheelset as an upgrade to the factory alloy wheels on my gravel bike. Out of the box, they are incredibly true. Great product totally worth the money.

    Amazing wheels!

    • Familiarity: I've put it through the wringer

    I needed new set of Gavel/Cross wheels for my Trek Domane. These are light, responsive and durable. I have 600 miles on these with no issues at all.

    Great finish to my Ridley X Night

    • Familiarity: I've used it several times

    I just built up my new Ridley X Night and needed a set of wide, but not too wide, wheels to due it justice. The Merc G-1 fit the bill with a 25mm wide (internal) spacing. I read a few of the previous reviews and everything they said was spot on.

    Stiggy likey

    • Familiarity: I've used it once or twice and have initial impressions

    The wheels are a big change from the WTB set. Lighter, wider and feel more responsive. Tubeless set up easy and the tires now feel a bit floatier (probably not a word). Nano's now measure out at 41mm and barely fit in the back of the Stiggy. Longevity? Who knows just a few miles so far. They were dead straight out of the box.

    Stiggy likey

    Versatile cross/gravel/XC wheelset

      These are currently on my Pivot Vault CX bike with Schwalbe Pro1 28mm tubeless tires. I use this bike as my daily driver trainer, and, the 28mm tires look, and, ride beautifully. I've also run Maxxis 700X40 Re-Fuse tubeless for winter tires, seating the tires has been effortless with just a floor pump.

      Two layers of quality rim tape, and, gorgeous red aluminum tubeless valve stems that were the perfect length were included.

      I settled on this set because the rim is actually lighter than most narrow carbon road clincher rims due to the hookless (stronger) bead, and, I'm ecstatic that the 28mm tires fit perfectly, they are almost the same width as the rim.

      Best part was that I purchased 135mm QR axles and they were the easiest axle swap I've ever done, allowing me to swap these to the 29er vise, no cursing, no re-dishing the wheels..........Yes, they were easier than DT swiss axles to swap

      What well-kept secret Mercury wheels are!, I was so Impressed, I looked them up, and met the owners and staff that build these great wheels......great people too, and, was even more impressed with the build quality when they showed me the process and, materials. Look them up if you're ever in Utah

      Unanswered Question

      On the Mercury website it states that these wheels ship with the adapters to switch to QR and to 15 mm in the front. Do those come included if the wheels are purchased from Backcountry? If not can you get them and for how much?
