Re: pic: Smoooooooooooth!!!
It does have a centering track that rides in a groove in the pulleys... we got the tracks from brecoflex..
we used the tracks themselves last year with a different frame and we happy with them.. they did suck a lot of power though.. so we wnet with this frame design and better bearings..
The wheels are made on a rapid prototyper out of abs plastic..
