The Story:

Our 2019 off-road line up has been redesigned for the new season to get your rig up the mountain, across the gravel 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, a gravel grinder 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 G3 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.

They're also available in two sizes - 700c (29") or 650b (27.5") to help fit a multitude of applications and/or conversions.
