45Nrth Concave XL Studs Pack of 300

These studs are pretty much impossible to beat for their grip over others studs on the market and they make a huge difference over standard, non-concave studs, especially in fat bike tires that don't have studs on the outer edge of tires. I've had these grip well on dense hardpack ice where other studs just skidded around like they were an ice skate. Very well suited for the Wrathchild 27.5 tires. While a tad expensive for 300pk, at least I don't have to worry about buying any for awhile as my tires shed studs.

These are the studs buy.

They grip like crazy. A must here in Alaska with our variable winters and long shoulder seasons.

I use them to make custom stud patterns on my 2.6 wrathchilds (full suspension trail) and my fat bike Dillinger 4 and 5.

Follow the companies instruction for install with isopropyl alcohol and they will not get pulled out.

I rarely have stud shed, and if i do loose a few in a season, it is better than a broken arm. Worth the money.

It's amazing the confidence that these studs add to fat biking. I installed these on 45NRTH Dillinger 4's for my Beargrease and it makes a world of difference in added confidence and safety, and adds days that would be non-ride days due to icy conditions, worth the $ 100%.

Like the XL concave on my dillinger5 on the sides of the tires so the grab a lot more in corners !

I use on my fat bike tires they work excellent and hold up well.

Used these to stud a Terrene tire, holding in the tire well, great traction on ice. Also replaced some studs in a Vee tire that had some missing and they fit fine.
