We've been enjoying the eager speed of Mercury Wheels' road rims since the Utah-based company recently debuted, and with the advent of the X3 29in Wheelset, many Competitive staffers are rocking the speed of the winged-saddled god on the trails, too. You know the advantages of 29-inch wheels — a higher approach angle that effectively flattens obstacles, more contact for better traction and power transfer, etc. — but the X3's selling point is that it hits all those marks with at a respectable claimed weight of 1,624g and a price point that puts these XC wings within reach of recreationalists and aspiring racers alike.
The X3 rims are an XC-specific model, built from a lightweight, stiff aluminum that lives up to the trail-furniture-be-damned attitude that their efficient ride quality inspires. At 24mm, the tubeless-ready rims are a touch wider than many XC race models still coming out of Europe, so they'll seat slightly fatter tires at a lower PSI with less chance of rolling off while leaving hot tracks across a berm. In addition to a safer setup, the wider rims also allow more tire volume, grippier cornering, and less rolling resistance.
Mercury's six-bolt rear hub is convertible for use with either 135 or 142mm axles, so they're compatible with most current frames and they're proof against the dimensions of what looks to be the likely future standard. Though the adapter isn't included here, it's nice to know it's available. The increased efficiency of the larger axle size is complemented by oversized flanges and double-butted Sapim spokes to take full advantage of a 29er's natural predilection for speed.

- Q & A
Wheels are an oft overlooked but very beneficial bike upgrade. Upgrading wheels provides weight savings where it matters the most - in rotational weight. A lighter wheel means you're pushing less weight with each revolution. These were an upgrade for my wife's bike and she is stoked on the weight lost - and the speed gained. These haven't seen too many trail miles yet but all indications point to them being a long-lasting durable wheelset.
High quality, low cost
- Familiarity: I've put it through the wringer
I used the Mercury X3's on my carbon 29" hardtail for a season and I loved them. Yes, I'm a Mercury fanboy but for good reason! Mercury offers excellent wheels at affordable price points and the company stands by their products. The wheels are hand laced here in Utah.
The X3's are light and plenty stiff for my 200 lbs. Traditional build and lacing means maintenance is a breeze.

Do these come with rim tape for tubeless set up?
These do not come with rim tape for a tubeless setup. You would need this Item #EAS001N, tires and sealant. If you give me a call, I could have the shop set up your tubeless wheels! All I'd need from you is your choice in tires! My email is KLamb@backcountry.com // 801-204-4567
What is the difference between the HG and XD body options?
HG is for that 10 spd from Shimano or Sram and that XD is for Shimano or Sram 11 spd! Feel free to shoot me an email directly if you have anymore questions!
