John's Mercian fitted with sprints as done in the 50's. Sprint wheels on alloy carriers with extra strap for security.
On arriving at race event the saddlebag and mudguards came off and the sprints replaced the 'pressures'.
After the event the procedure was reversed and the set-up was often ridden for an extra hundred miles or so on a club run.
