What does refurbished mean to us? All of our bikes get overhauled from top to bottom. Each bike is stripped down to just the frame, washed, and rebuilt using a mixture of new and overhauled used parts. All of our bikes get brand new wheels, tires, tubes, brake pads, chains, freewheels or cassettes, bottom bracket, and cables & housing. Most also get new grips, pedals, brake levers, seatposts, and saddles. Some get new derailleurs, brakes, handlebars, or headsets (as needed).
