The Bont Tracer plate is the perfect plate for any skater. The chassis is crafted from extruded 6061 aircraft aluminum with one-piece cast trucks to make this plate strong and affordable. The 20-degree kingpin angle is great for making tight turns as well as top-end speed and stability. The plate will suit kids, boys, girls, women, and men of all abilities and ages. It can be used for indoor skating, outdoor skating, rink skating, and roller derby. This aluminum roller skate plate is an upgrade over a nylon skate plate. This plate is suitable for all types of roller skating, not just roller derby.
