What is the difference in compound and size?Updated 2 years ago
Compound
The compound is the hardness of urethane in street wheels. The higher the number, the harder the compound/durometer.
- Lower durometer wheel = softer wheel and adds more grip (e.g. 74a, 107mm ABEC/Evolve)
- Higher durometer wheel = harder/stronger wheel, slides more easily and it best for aggressive riding (i.e. 83a, 85mm Purple Caguama)
Size
The size affects the top speed and torque.
- Smaller wheel = lower speed + faster acceleration/torque (e.g. 85mm Caguama)
- Larger wheel = higher speed + slower acceleration/torque (e.g. 107mm ABEC/Evolve)
