Re: Denver help...?
Dark Ride, i suggest you look at the thread featuring Easy Rider's bike with the Morini engine. setting aside all other questions of what's good, bad or legal. there's a suspension bike with disc brakes that apparently easily goes beyond 40 with no problem at all.
i have no interest in going 40 and i'm not taking sides in this argument, but if you want to see what a 40+ bike looks like...
