Aero / STT
The big challenge for wheel engineers is to reduce weight while maintaining aerodynamics. Typically these design elements are not available in a sub $1k wheel. Luckily, we already made the fastest wheel in the world and translated some of these into the S4.
Using Mercury's Seamless Transition Technology (STT), we;ve integrated the brake strip with the rest of the rim in order to eliminate any obstructions to wind flow and reduce drag-causing turbulence. The result is a wheel that shares the aerodynamics of a deep dish or solid disc, while being much lighter. As a result, the S4 is Mercury's most popular wheel by far.
Spokes + Hub A professional wheel builder will build your wheel by hand. The S4s come with Sapim's indefatigable Race spokes and Mercury's custom hubs. We've found this combination, particularly our low friction sealed-bearing hub, brings an engagement that's as close to immediate as anything we've seen on the market.
The front hub has an extra-wide 70 millimeter flange for reduced flex under hard efforts and confident stability at speed. Both hubs have an oversized axle that reduces to accommodate a traditional quick release and two and four oversized bearings in the front and back, respectively.
The S4's construction uses Mercury's Dual Carbon Layer Process, or DLP. DLP blends high and mid-moduli carbon fibers to tease out the best balance between the lightweight and stiffness of the former and the fatigue-resistance and durability of the latter. DLP also involves the incorporation of basalt fibers in the brake track to reduce heat build-up and increase stopping power.
This increased stopping power goes a long way toward addressing the poor braking that is one of the most common critiques of carbon wheels.

Our 2021 alloy gravel wheel has been redesigned for the new season to get you across the gravel bliss without a hiccup.
Two word that you will get used to hearing with this wheel set is simplicity and durability! The rim is a solid 25/30mm 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 brass nipples to further emphasize the durability of the wheel set. They are centered around our sealed-bearing Mercury designed hub set that can convert from thru axle to QR easily so you can use it on your whole fleet of bikes. The set comes in at a respectable 1799g for the set
They're also available in two sizes - 700c (29") or 650b (27.5") to help fit a multitude of applications and/or conversions.
Your perfect training partner.New to the Mercury line up is the M1 clincher. The all new tubeless compatible rim profile coupled with our proprietary alloy brings a stiffer and lighter set of wheels. We utilized Finite Element Analysis (FEA) to optimize the strength to weight ratio, lateral stiffness and durability.
We laser etch the Mercury logo on the rim to keep your wheels looking as good as the first day you mount them! We all know that keeping your wheels looking good is always a battle. Between road grime, rock chips and mud wreaking havoc, the last thing you should worry about is that vinyl decal falling off.
Our hubs boast wider flanges creating additional lateral stiffness, the axle has been optimized to lower the weight without compromising performance and 6 sealed cartridge bearings.
What does this all mean? Expect one of the smoothest and most durable set of training wheels you will ever ride
Rim(s) / Size: Mercury M1C / 700c

The G1 carbon gravel specific wheel is Tough enough for any road your adventure ride might throw at you. Plenty wide to accommodate a wider tire for a stable platform, these rims are built to withstand the roughest of roads, built around our MTB hubs and are rounded out with Sapim double butted spokes.
You will LOVE the durability of these wheels when things get rowdy.
Minimum tire width recommendation > 35mm and for use with pressures not to exceed 75psi (5.10 Bar)
