45NRTH | Unparalleled Cold Weather Performance

Also other cold weather gear -- boots & gloves -- that looks interesting.

I chose the 120tpi due to weight + folding vs wire rim -- I'm frickin' tired of fighting wire rims, especially in the cold

I'm pretty sure the aluminum is just the casing around the stud, not the stud itself. All decent quality studs are made with carbide studs now.

You are correct. It was my misunderstanding and it did seem a bit odd. Here's how 45nrth describes the two options:



Concave Aluminum Carbide Studs
This stud features a carbide tip with a concave shape on the crown. The concave crown creates a very sharp attack angle to the surface, resulting in an unparalleled amount of traction. Any wear that occurs to the carbide crown creates an even sharper edge – continuously augmenting acceleration, braking and cornering performance as it ages.




Steel Carbide Studs
Using the same two-piece construction method as the Concave Aluminum Carbide product, the steel-carbide stud features a dome-shaped carbide tip with a steel base, making it a more economical stud for 45North’s 27tpi tire collection, while still providing excellent performance and longevity.

Or are you referring to weight?
