45NrthConcave Studs Pack of 100(Return to Product Page)

I use these on my cross trail for winter riding. Good grip on ice or packed snow.

Studded my 45Nth fatbike tires, seemed to work well, would highly recommend the stud installation tool.

Great long lasting studs for Wisconsin Winters

Learning experience for installation for this newbie. Not much snow left, so not a lot of experience on them yet.

Really amazing. I ride every day 365/ work/ home/ exercise ext... i fell twice last year real hard at 5 am on black ice to work. So this year bought 45NRTH Tiers and these replacement studs and haven't fell or even came close to crashing. TRULEY AMAZING!!!!!!!!!!!!!!!!!!

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.

Very easy to install. Works great in icy conditions. Great price and shipping expense
