First, Holy Thread Revival, Batman!
I retired my Raleigh Pro Track from mass start racing when it got to be about 20 years old--it was too pretty to put into those small holes at the back of a miss-n-out. Had I done any more kilos or pursuits, it would have been my first choice, as it was easier to put my TT bar setup on it than my threadless Davidson. I did continue to ride it on the occasional training night. That's the only bike of mine that has had any change in the use I expect of it. I ride everything else without reservation.
