Schwinn 684 circa 1992, size small. Excellent condition for it's age, aluminum frame, Shimano 105 derailleurs, calipers, indexed shifters, new bar tape and saddle. $400

Cannondale This is an early Cannondale road bike, maybe even from the 80's. It's extra small, and was stored so that the elements didn't get it. As far as we can tell this is all original and complete. $350

Cannondale R900 54cm road bike, ball burnished and polished aluminum frame. Mavic rims, Shimano 600 crank, derailleurs, and shifters. $700

GIANT Simple Single This is a beautiful condition used bike. GIANT aluminum cruisers are probably the lightest cruisers, and with aluminum wheels they ride easier than most cruisers as well. This one has a perfect paint job and brand new tires. $275


New Belgium Fat Tire Ale promotional single speed cruiser, by Felt. Sturdy, rugged, and durable. $450

Schwinn 70's best guess is it's a Traveler. It's 5 speeds, everything works, recent new tires and tune-up. $100
