What to look for when buying a used Unknown
When buying any used Unknown, start with the basics. Check the frame for cracks, dents, or damage, especially around the head tube, bottom bracket, and dropout areas. Look at the drivetrain for wear and make sure the gears shift cleanly through the full range.
Ask the seller for service history and proof of ownership. Every Unknown listed on Cyclesite is automatically checked against a stolen-bike registry and rider-filed theft reports, but it is always worth checking the frame number yourself too.
