45NRTH Concave Carbide Aluminum Studs

The concave shape acts like a claw, biting into ice more aggressively than a flat tip. This design increases the surface area that makes contact with the ice, providing significantly better grip and stability when cornering or braking on slick surfaces.

While you might be tempted to use pliers or a screwdriver, we strongly recommend using the dedicated 45NRTH stud insertion tool. It ensures the stud is seated at the correct depth and angle, preventing damage to your tire casing and ensuring the stud stays secure during your ride.

These studs are designed for tires that come pre-drilled with stud pockets. Before purchasing, verify that your specific tire model has the correct hole diameter and depth to accommodate these studs.

The aluminum base is primarily about weight savings. By reducing the rotating mass on your wheels, you keep your bike feeling nimble and responsive, which is a noticeable advantage during long winter rides.

Not necessarily. You can replace individual studs as they wear down or go missing. However, if you notice a significant number of studs are dull or damaged, replacing them in sections or across the entire tire will provide more consistent traction.
