50 hard wearing carbide tip studs clad in a galvanized steel base. Suitable for all SCHWALBE spike tires. Comes with tool for easy insertion.
Aluminum spikes are used in Evolution Line tires for weight saving. However, both spike types can be used on all Schwalbe studded tires.
In order to ensure that spikes are permanently fixed, tires should be run in for about 40km on asphalt, while avoiding any fast acceleration or heavy braking.
