Landroller Skates

I have an interesting question about the new skates.I Landroller wonder if any engineers out there can calculate the difference in efficacy between the wheel angle Landroller compared to the configuration of the wheels straight skate average line. I think variables include forces acting on the bearings (bearings are the same type for both skates), the friction between the wheels and the ground, and the overall movement of the wheel. Because Landrollers have bigger wheels, they are clearly better on rough surfaces and I think the calculation should be optimized for terrain conditions (flat). If you're really good you could include the two large wheels to four wheels from the smallest configuration in the calculation, but again, different surfaces give different results. I think this assessment is important because Landroller sells skate on the Internet and once you try you can not return them if they turn out to be garbage. They certainly look great!

They are mounted by the dog whisperer "or they could go out of business today.

Small differences due to the list of items you are overshadowed by other issues.
Wheels inclined to place more emphasis on ball bearings (bearings 608 do not react well to the side forces).
Replacement wheels are available only from Landroller. You do not have the choice of materials and hope they have always done at a reasonable cost. Ditto for the brakes.
The quality of the urethane is much more important than differences in the bearings. Most managers swap rolling capacity for more wear.

A big problem is that they have only two wheels. This in itself limit your ability to bend. The tight turns on a normal skateboard would be to put most of your weight on the rear wheels and front wheels leave the scrub on the side a bit. Can not do that with only two wheels.
