What’s the Difference Between Wheel Compound and Size?

When choosing street wheels, compound (durometer) and size play a big role in grip, ride feel, speed, and acceleration. Here’s what you need to know.


Compound – How Hard or Soft Are Your Wheels?

The compound refers to the hardness of the urethane, measured by durometer (A scale). Lower numbers mean softer wheels; higher numbers mean harder wheels.

  • Lower Durometer (Softer Wheels)
    More grip
    Smoother ride on rough surfaces
    Better shock absorption
    ⚠️ Slightly less speed and durability

    Example:

    • 107mm ABEC/Evolve wheels (74a)
    • 105mm Dad Bods (77a, 80a)
    • 97mm SuperGrips (76a outer urethane with a 55a core)
  • Higher Durometer (Harder Wheels)
    More slide-friendly for aggressive riding
    Increased durability
    Less rolling resistance = more efficiency
    ⚠️ Harsher ride on rough terrain

    Example:

    • 85mm Purple Caguama (83a)
    • 97mm SuperGrips (firmer internal core for extra control)

SuperGrips Specifics:
The 97mm SuperGrips offer a unique blend of 76a outer urethane for grip and a 55a internal core for cushioning. This combination provides a smooth ride with enhanced grip and control, making them ideal for high-performance street riding.


Size – How It Affects Speed and Torque

Wheel size impacts top speed, acceleration, and ride comfort.

  • Smaller Wheels (e.g., 85mm Caguama):
    Faster acceleration and torque
    Better control and agility
    ⚠️ Lower top speed

  • Larger Wheels (e.g., 107mm ABEC, 105mm Dad Bods):
    Higher top speed
    Smoother ride over cracks and bumps
    ⚠️ Slower acceleration


Which Wheels Should You Choose?

  • Need grip and a plush ride? → Softer compounds like SuperGrips (76a), ABEC 107s (74a)
  • Want durability and sliding control? → Harder compounds like 85mm Caguamas (83a)
  • Looking for max torque and quick acceleration? → Smaller wheels (85mm)
  • Chasing top speed and smoothness? → Larger wheels (105mm–107mm)
