More Grip, Less Slip

45NRTH is the undisputed champion of cold weather cycling. Their Large Concave Tire Studs utilize a two-piece construction and concave carbide-aluminum design to create a reliable, high-traction bite into snowy and icy conditions. 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 durability and longevity
  • Aluminum base to save weight
  • Compatible with the 45NRTH stud insertion tool
  • Available in packs of 25, 100 or 300

After entering a zen like state during the several hours long stud installation process, I no longer eat shit at any slight deviation from straight on snow/ice covered trails. In other words, they work great!

They will do the job.

OEM brand studs that were in 45Nrth Dillinger 4 tires. Tough, durable studs for studdable winter fat-bike tires. Have the end of the stud tool/stud wet makes removing old studs and installing the new ones a lot easier!

I haven't needed any replacements yet for my tires but they look like they will work just like the originals on my Wrathechild tires.
