gripSpeeder Five Wheel Setup


 

Combining two 110 mm wheels with three 56 mm wheels, the gripSpeeder seeks to combine speed with grip.  The middle three wheels only touch the road during acceleration, turning, and braking. The middle wheels are 4 mm off the road until you push extra hard for added grip.

They look like they would be fun to play with. The skate would sit much lower than the standard setup with the 110 mm wheels in front of and behind the boot.
