Concave Studs

Concave Studs

Using the same two-piece construction method as the standard carbide-aluminum product, this stud features a carbide tip with a concave shape on the crown. The concave crown creates a very sharp attack angle to the surface, resulting in an unparalleled amount of traction. Any wear that occurs to the carbide crown creates an even sharper edge – continuously augmenting acceleration, braking and cornering performance as it ages.

Carbide-Aluminum Studs

Carbide-Aluminum Studs

Balancing high density with weight, our carbide-aluminum studs are assembled from two components: an aluminum base with a carbide tip pressed into it. Being the next dense material to diamonds, carbide resists wear from constant contact with asphalt. The aluminum bases that hold the carbide tip are half the weight of stainless steel, significantly reducing the constant rolling weight of the tire. The combination of super durable carbide and super lightweight aluminum provide the optimum balance of durability and performance.

Steel Carbide Studs

Steel Carbide Studs

Using the same two-piece construction method as the Concave Aluminum Carbide product, the steel-carbide stud features a dome-shaped carbide tip with a steel base, making it a more economical stud for 45NRTH’s 27tpi tire collection, while still providing excellent performance and longevity.

Aerogel Insulation

Aerogel Insulation

With its nano-sized air pockets that block cold and heat, aerogel is an ultra-thin, compression-resistant and waterproof insulator with the lowest thermal conductivity of any solid. It is the same insulation NASA uses to protect astronauts and sensitive equipment on missions to outer space. Created by extracting the liquid from silica gel, aerogel produces a strong, durable and flexible material that is up to five times more effective than traditional thermal insulation. Other insulation materials require loft to insulate. Aerogel does not need loft to deliver its high insulation value, making it an ideal insulator between your body and cold contact points on the bicycle.

Waterproof-Breathable Membrane

Waterproof-Breathable Membrane

An ultra-thin sheet of microporous material behind our textile shells keeps you dry and warm in the harshest weather conditions. Liquid water molecules from outside of the garment are larger than vapor molecules created by body heat from the inside. The microscopic pores are smaller than liquid water molecules, but larger than vapor molecules. As a result, waterproof-breathable membranes stop liquid from the outside, but release vapor from the inside for thermal and moisture regulation.

Anti-Slip Microglass Rubber

Anti-Slip Microglass Rubber

Microscopic glass fibers are electrostatically aligned in the rubber compound to create abrasive protruding shards. These shards are the microglass filaments that create friction on slippery surfaces such as ice, wet wood, wet linoleum and wet metal found on many stairs and floors. This friction is achieved by breaking through the layer of surface liquid between your rubber sole and the ground.

Siping

Siping

Tiny grooves on large tread lugs create more edges for grip. These grooves also give the tire more flexibility to move over surface undulations, providing enhanced acceleration, braking and cornering traction while also creating a more comfortable ride quality. Siping has been used in the automobile industry for years to augment the performance of tires in winter driving conditions.

Merino Wool

Merino Wool

Originating from the Merino breed of sheep, this wool is naturally very fine and soft to the touch, while also having an incredible warmth-to-weight ratio from microscopic cortices of dead hair that trap body heat and store moisture. When wet, this wool can absorb 30% of it’s weight in water before feeling wet to the touch, making it an excellent insulator in the harshest of conditions. In addition to all these benefits, merino is also naturally antibacterial, making it excellent for multi-day excursions.

Tubeless Ready

Tubeless Ready

A large flat edge on the bottom of the bead results in more surface area contact with the shelf of the rim. This increased surface area creates a more effective and secure seal for tubeless set ups. The surface of the entire bead is also smooth, reducing the number of small gaps that allow air to leak between the bead and rim shelf. Running your fatbike without tubes can reduce the weight of each wheel by 300 grams and provide a suppler ride quality. Always consult rim manufacturer instructions before setting up tubeless tires to ensure safety and compatibility.
