45NRTH utilizes a two-piece construction method to create a reliable and high-performing bicycle tire stud, featuring a concave carbide-aluminum design. The super-sized concave crown creates open space and inside edges of the bowl, resulting in twice the surface area for increased traction and grip.

The concave crown creates a very sharp attack angle, resulting in an unparalleled amount of traction. As the carbide crown wears, it sharpens the edge further – continuously improving acceleration, braking, and cornering performance.

The aluminum base is half the weight of stainless steel and significantly reduces the tire’s rolling weight, and the carbide tip rivals the hardness of diamond. This combination provides the optimum balance of durability and performance.

The large studs offer more stability than the regular stud and less rolling resistance than the XL stud.
