Thanks for the 4-spoke info, Taras. I know they are burly, and I have the special tandem/sprinter/fat guy version, but does anybody know if they're considered fast? I got mine for a reasonable price, and I can't afford anything else, I'm just curious. And that extra molding flash that you mentioned-- has anyone removed this? Is it safe to do so? Seems like that alone would considerably clean up the aerodynamics of the wheel.
