Finding bikes built by the Specialist Bicycle Development Unit (SBDU) that aren’t what they appear to be is part of the appeal of bike hunting and collecting for me. These are bikes and frames are hiding in plain sight, often with other builders frame transfers or paint schemes. They are flying under the radar, going unnoticed, and masking their real origins. SB8851 is a prime example. It is fitted with Dave Quinn transfers and came with a story that it was ordered from and built by Dave, but a closer look the at those frame features gave it away.
