Pinarello was doing this in the 1980s and 90s as a stylistic "flourish". They also supplied threaded allen key bolts that had no "head" so they could be screwed in just below the surface to fill the hole but be smooth and less visible. The resulting look was presumably sleek..... This is not a difficult procedure in frame building, the standard machined bit is brazed into the frame, then the top cap filed or sanded off, creating a flush surface. I have also seen this done on the seat tube where otherwise the water bottle fittings interfer with a seat tube mounted pump....

Can a frame builder out there help me with a question that has bugged me for years. I have a nice red and chrome lugged Pinarello. The down tube is drilled and threaded for a bottle cage but there are no external bosses. It is clear from the depth of threads that there must be bosses inside the tube. How the hell do they do that? I feel it is rather pointless as although it looks neat on the bare frame when you mount a cage it is hidden. Ray Green, Brighton, England
