Well the maple i had kicking around, the wheels were 2$ each, but we'll see how much the new one's are, and i'll just pull the bearings from my old skateboard wheels that are to big. i know the alu tubing is 20$ for enough to make a set of rollers. I'd say i'm well under 80$ even with having to do things twice to get it just right.

I do agree that it takes a bit more finess to ride rollers, and i definitly can. It was just sort of agervating not being able to do any sprints, or alot of climbing simulation indoors over the winter. I think it just feels more realistic, maybe i'm taking away from what rollers are supposed to do to your trainning though, of course i'll always have the option to just take it off the free motion frame and lay it on the ground so...
