• 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.

  DLP

  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.

This increased stopping power goes a long way toward addressing the poor braking that is one of the most common critiques of carbon wheels.

Aero

The aerodynamic benefits of a deep dish rim are further complemented by Mercury's Seamless Transition Technology (STT), which integrates 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 of this construction is a wheel that balances the above qualities with considerations of weight for our most popular wheel by far.

Spokes + Hub

The S5s are finished off with Sapim's indefatigable Race spokes and Mercury's own hubs. The rear hub includes a generous six pawls for an engagement that's as close to immediate as anything we've seen on the market today, and 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.

Warranty: 2 year(s) against manufacturer's defects extended to the product's original owner. Mercury brake pads MUST be used exclusively with rim brake wheels - other brands of brake pads voids any warranties.

The Story:

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
