If you’re in the Chicago area, make sure you head out to one of these local hotspots and pick up a Thought You Knew (TyK) Pin-Up calendar. With 100% of the proceeds going to the Chicago Women’s Health Center, and a slew of sexy ladies gracing the pages, it’s definitely something worth checking out. Plus, the monthly hotties aren’t your run-of-the-mill models; they’re everyday girls, bike messengers to be exact! The gal behind this project, Alexis Finch, rounded up her fellow female 2-wheelers, and photographer Michelle Nolan carried out the project. They’re hoping to tear down any preconceptions about these women’s femininity, while helping out the CWHC. After you’ve seen these pics there’s no denying these cyclists are bad-ass, and gorgeous to boot! Read Michelle Nolan’s interview with Time Out Chicago here.
