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.

  • Aluminum base to save weight
  • Sold in a pack of 100 or 300 studs
  • Use with 45NRTH Stud Insertion Wrench
  • Compatible with tires from 45NRTH, Terrene, Bontrager, Maxxis... they are interchangeable

45NRTH Carbide Studs

I replaced the original carbide studs on my Dillinger 5 Fat Bike tires with the new 45N XL. I did this because the original studs were not very effective on ice, especially hard brittle ice. I have been using the new XL studs now for the past month and am very pleased with the performance. Much better than the original studs. The XL studs are very, very grippy in all ice conditions, especially hard brittle ice. Ice covered hill climbs and twisty trail turns are no problem. My riding confidence with these studs is greatly increased. I would recommend these to anyone looking for a better ice stud.
