45NRTH uses a two-piece construction method to create a reliable, high performance bicycle tire stud with an aluminum carbide concave design. The open space and edges created by the large concave crown results in twice the surface area for increased traction and grip.

Concave toe for traction, durability and longevity
Aluminum base to save weight
Compatible with 45NRTH stud insertion tool
The large lug offers more bite than the regular concave lug and less rolling resistance than the XL lug
Sold in packs of 100
We design 45NRTH tires for extreme winter cycling applications. We do not recommend this product for use with e-bikes, as the added torque and weight of the system can cause premature case wear and loss of studs.
