one of our local riders (Josh Summey) is racing supercross this year on the big bikes. he also is one helluva mtb'er. I picked up his stp the other day to take the gears off and make a cheap s/s drive train and tune it up. I was prepared to install a rennen but found a magic gear that worked out stellar. bike's pretty sweet. profile front and rear hubs, proto 4x-ish fork from marz, boone ti cog and spacers, 30.5#s. It's held up pretty good. He said he hit all the big DJ spots in cali when he was out there at the first of the sx season this year and never had any issues. check it out:
