No, the three 125mm wheels are actually lighter than four 110mm wheels.
No, as there are only three wheels, the 125mm skate actually allows for a shorter setup than 110mm wheels do.
No, the 125mm setup is actually just as high as a regular 110mm setup, and the Asian skaters that use 165mm mounting distance actually stand higher than those that use the 125mm setup.
No a set of 6 times 125mm wheels will cost exactly the same as a set of 8x 110mm wheels.
So now the only remaining argument is: Too fast?
Well first tests show that the 125mm setup indeed is faster than any other skate configuration. But aren?t we all looking to become faster?
