SB7393 Raleigh SBDU Ilkeston Reynolds 531 Professional 1985 – Geometry and Design

Time Trial frame? Road frame? Or a bit of both? What exactly is it?

SB7393 came with a story that it was built and used for time trials and ridden by a junior. I was also told by Rob, the previous owner, that it was a “lively” ride! It looks like a conventional SBDU road bike, but then again, SB time trial frames can look like conventional road bikes too; and with vertical and horizontal ends as options on both types, it is ultimately down to geometry to unravel the puzzle.
