More is more.
Whoever said less is more clearly had never been on a mountain bike. On dirt, a few curves and a lot of squish have become hugely desirable traits, and ones we anticipate seeing a whole lot more of in coming years. Of course, you can't fully benefit from your pudgy, fun-loving new set of donuts if you try to wrap them over too-narrow rims that make them feel sloppy, so invest in the Mercury X3 Enduro 29in Boost Wheelset to give them the expansive partners they deserve.
Made out of a lightweight, durable alloy, the X3 Enduro makes a worthy upgrade for the stock hoops you've been meaning to replace, and it won't blow your entire trail travel fund for the summer. While alloy isn't as stiff as carbon, the improved spoke bracing angle of Boost axles conspires to reduce flex while dancing up climbs and cleaning jarring lines. With a 29mm internal width, the X3 will welcome your plump new tires with open arms onto a plush platform that maintains trail dexterity while it softens your ride. Though any enduro beast stands to gain plushness wider tires and rims deliver, slacked-out hardtail 29ers just might stand to benefit most from added squish in the front and back.
- Give your plump tires the perch they deserve with this rim
- Lightweight, durable alloy won't break your budget
- Plump tires sit low and wide on this accommodating rim
- Boost axle spacing stiffens and reduces torsional flex
- Hubs convertible to different (future) axle standards

Soft as cheese
- Familiarity: I've used it several times
These are the softest wheels on Earth. I'm 155 lbs and these are my second set. The first pair came with a small dent in them when it was brand new. Backountry was awesome and sent me another set. Rode the new set a couple of times around the local trails which are considered smooth as a baby's butt and all is good I thought. Running Hans damph front n rear at 21psi rear n 19 psi front. Was about to go to a real backcountry mtn trail over the weekend so I always do a bike check. Low and behold it's dented again. Where the dent is is not even a scratch or a ding or something that would tell you major impact. I should of known after the first set came dented. So I put on my old set of stans flow ex that I replaced by buying these. They have scratches here and there and I'll admit I've hit rocks and think they're done for but always got me home. Plenty of scratches and scrapes but not a single dent. These Mercury are dented enough that one is would be wary of them having a major burp at any moment. Gonna see what backcountry can do for me but I do not recommend these. I was actually about to purchase the 27.5 version for my other bike but no way am I going to now. Hope this review helps. Btw I took the old Stan's to a rocky ass trail in the GWNF and was rock smashing all day this past Sunday and not a single dent still. These are truly soft ass wheels.

I just added these new Mercury wheels to my Niner and just love them. Super stiff and they take a pounding, plus at a great price.
What is the difference between the XD and the HG?
Also my current rear hub is 12x142, will the 12x148 work?
XD is for SRAM cassettes with a 10 tooth smallest cog. HG is for Shimano and other brand cassettes including SRAM with 11 tooth smallest cog. 148mm is to wide for your current bike that uses a 142mm hub spacing. 12x148 is also referred to as "boost". There are plenty of 12x142 wheels to choose from.
