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 durabilityExample:
- 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 terrainExample:
- 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 speedLarger 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)
