Footprint Modulation, and more
The durable, surface-hugging outer material on MPC Speed Wheels is high performance urethane (just the thing Mearthane is known for), but it's what's inside that counts.
Most race wheels have a physical interlock - a part of the plastic hub that extends into the tire to physically tie the tire and hub together (like steel reinforcing mesh in concrete). MPC wheels do not have a physical interlock, the hub is bonded to the tire. This means the urethane material depth is maximized from the top of the wheel to the hub - making for higher rebound and better ride quality.
Because of the soft inner (62A of 'super-bounce ball' material), this rebound is made even greater. When the wheel stands vertically, as it does for most straightline skating, only the outermost 5-6mm of material is the outer urethane.
Without a physical interlock, and with a flexible inner material, the wheel's tire actually deforms (changes shape) to improve its performance in corners. As the forces on the wheel increase, the inner material flexes, allowing more of the outer urethane to contact the surface - providing more grip. Effectively, the wheel footprint is one shape for straights, and another, force-dependent shape on corners.
This is where Energy Management Technologies and Flex Bands came from.
What does that mean for the skater?
Increased rebound means more energy return. It also means improved ride quality. The super-resilient inner material used in MTECH technology is unique to MPC wheels, and plays the key role in their speed potential.
The engineered footprint modulation (the ability for the wheel to adapt its footprint shape and size) means the wheel provides low rolling resistance for high speed in a straightline, and increased surface contact and grip in corners - when you need it most.
...and it's not just about the tire
Each of the hub's 9 spokes 'twists' its way between the inner and outer hub rings. This twist in each spoke allows side load (the type applied through corners) to twist the hub slightly, adding to the potential footprint being applied by each wheel on the surface. 'Hinge points' in some other wheels, allow the wheel to 'snap back' into place after it has flexed. MTECH hubs do this by design.
