Throughout your time on the ice, a few studs are bound to get sacrificed to winter's harsh terrain. Replace your fallen studs with 45Nrth's Concave Studs - Pack of 100. They feature a concave carbide-aluminum design and a two-piece construction method that creates a reliable, high-performing stud. The concave crowns provide a sharp attack angle for excellent grip, and as they wear, the edge only gets finer to maintain performance throughout their lifespan.

Features & Specs:

  • Durable concave tip.
  • Lightweight aluminum base.
  • XL features a larger carbide tip diameter.
  • Compatible with the 45NRTH stud insertion tool.
  • Sold in a pack of 100.

I bought these to replace the frequently missing studs on my Gravdal tires. Price is decent for 100 but it's a little annoying how often I need to replace them. They are a direct replacement for the original studs and the optional installation tool makes replacing them a piece of cake.
