Yes, more through the pneumatic tires, the rails difficult to say. I'm 215 lbs. and they feel like skis...more like a no bounce bike feel. A down hill run easy slope to feel out the ride. Anything techinal with 12" would take supreme balance and control. I do alot of inline speed at pro speeds and the 6" platfrom is just too much, maybe with more time that would change. 4" platform makes them more usable transportation.

here's a updated set up

dropped the 12" and reset with 8" (shared from my MBS).

the feel is better can actually "skate" including double push at decent speed.

so i can skate back if the wind is down.

i think most would prefer to use with poles for cruising.

still haven't hooked my 12m with these. and cautious cruising with NPW5

fall/winter will put more time on them

pic with 8" set up swap is <5min.

12 inch wheels will feel strange when standing or rolling when the body is mostly vertical, but all makes sense when leaning against the pull up a kite. 8 inchers are fine too, but the closer to the ground you are, the more likely you may skip-out (hit the rail to the ground) when powered up and leaning against the kite.

It is also when leaning that you'll notice the offset front wheel. When rolling vertical, it has no effect.

Remember, this setup is for kiteskating. Downhill or nordic skates require a different configuration.

i have the 12" set up with the off set. these i set up favoring the inside rail. more of a travel and versatility thing. looking to get into better wheel/bearing. the MBS worked perfect, the 9" version will give me more toy expansion use both board and skate set ups.
