What's up James? Going to go racing in the old fart's class?
I used to race DiamondBacks, Harry Leary was my hero back in the day! I still have a mid 80's Kuwahara Laser Light with the big CW Racing bars and I might still have a couple of ACS Z-Rims back at th folks place. I'd love to pick up an SE Quadangle but people want big bucks for them these days. Maybe we should get a few of us to the track this summer and have our own old fart races!
Back on topic... if you don't mind spending a bit of money to get something cool, check out PD's Hot Shop on West 4th and Macdonald. They always have a few 80's BMX bikes there but expect to pay $200 and up. Another good spot is Cheap Skates on Dunbar. The prices on stuff there go down the longer it stays there. Sorry, I don't know of anywhere closer.
