Just saw this posted on Craigslist:
Performance Cycle of Colorado is having our first annual Great Gear Swap! You can buy and sell used dirtbike and streetbike riding gear outside of our store on Broadway. Sellers it cost you nothing and the store takes nothing from your sales. Buyers bring cash for the great deals to be found. Sellers bring a table or tarp to lay on the ground to show your goods (please no big easyup tents). Sellers you are allowed a 6'x6' space. Set up is 8:30 am on Saturday and the hours are from 9:am to 1:pm on Saturday Aug 7th. The location is Performance Cycle, 1990 S Broadway, Denver, 80210. Call for info 303-744-2011 or go to www.performancecycle.com
Kinda late notice IMHO (though maybe it was advertised through other channels that I never see).
