Our 2018 XC line up has been redesigned for the new season to get your XC rig up the mountain and over the line faster than ever before. With many riders using wider, and wider tires these days, you may think that XC specific wheelsets are going by the wayside- not here at Mercury. Whether you are a serious XC racer, or just prefer the classic ride characteristics of a skinnier rim and traditional width tire, this wheelset is right up your alley. They can pick their way up a technical rock stairset as confidently as a Nepalese mountain goat, rip downhill, and corner with the precision of a surgeons scalpel.

Two acronyms that you will get used to hearing with this wheelset will be- K.O.M., and P.R.! Our XC wheels are all about efficiency, and getting every last watt from your legs transferred to the trail. The rim is a solid 30mm wide, and 24mm deep providing a stiff, responsive, yet forgiving ride. Our hand built wheels are laced two-cross with Sapim Double butted spokes, and alloy nipples to trim weight, all centered around our sealed-bearing, Mercury designed hubs that can convert from thru axle to QR easily so you can use it on your whole fleet of bikes, regardless of drop out standards. The set comes in at a respectable 1,644g. Which is only about 100g heavier than the competitions full carbon XC options, at about half the price.


Mercury supports standard 100mm and boost 110mm front wheel 15mm thru-axle systems. We can convert thru-axles to accommodate quick releases if your fork requires the use of a quick release. Front axle specifications are provided by your fork manufacturer.  Rear axle configuration is determined by your frame. You can find most in the specs section of the manufacturer website.

12x142 is the most common current rear axle configuration for all-mountain bikes.

12x148 is boost.  Rear axle configuration is determined by your frame. You can find most in the specs section of the manufacturer website.
