45NRTH uses a two-piece construction method to create a reliable, high performance bicycle tire stud featuring an aluminum carbide concave design. Oversized concave crown creates open space and inner bowl edges, resulting in twice the surface area for increased traction and grip.

We design 45NRTH tires for extreme winter cycling applications. We do not recommend this product for use with e-bikes, as the added torque and weight of the system can cause premature case wear and loss of studs.
