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

I used these to replace some others that were worn out in the middle of my fatty tire. They grip better and last longer.

I inserted these studs on a Dillinger 4.6 inch width tire that is on the back wheel. I have been riding almost exclusively on a groomed snow trail. The trail has sections of several hundred feet of pure ice at times. The traction on ice is great, I can't break the rear tire loose while seated and pedaling hard. I able to go up icy inclines and over cambered icy sections of the trail without any loss of traction. Corners on the ice are not a problem. I installed the studs on the Dillinger which is on the back wheel. I also bought a wrathchild pre-studded tire that is on the front wheel. The studs are light, and have held up well. I haven't lost any out of either tire. It wound be nice if they were a bit longer for traction on a skiff of snow over ice. They are expensive but much safer on ice than not having studs.

the concave studs really grip, I can honestly say that the wraithlorde tires with these studs are the best winter fat tire stud combo available.

Work as intended. 200 miles on them and they're holding strong

I bought these studs to replace worn and lost studs on my Rathchilds. They were easy to install and add to my grip on icy trails.
