Schwalbe Aluminum Stud Spikes 50 CountThese Schwalbe Aluminum Stud Spikes have pointed carbide tips, and so while not only significantly lighter than the steel version, they have a better shape to their head for grip in ice and snow. Alloy does not corrode in the same way as steel does, and so the only detraction is the slight cost increase relative to the Schwalbe steel cost. There are 50 studs in the kit. The Schwalbe Al Mighty Studded Tire 26x4.8 has 328 studs on each tire as a reference.4026495898553
