45NRTH XL Concave Carbide Aluminum Studs - 25X

45NRTH utilizes a two-piece construction method to create a reliable and high-performing bicycle tire stud with 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.

• Concave tip for traction, durability, and longevity
• Aluminum base to save weight
• Compatible with the 45NRTH stud insertion tool
• Sold in a pack of 25
• 45NRTH tires are designed for extreme winter cycling applications. They do not recommend this product be used with power assist bikes as the additional torque and system weight can lead to pre-mature casing wear and stud loss.
