Just some memories to share. Dad came home with a used bike in about 1972/3. Got it from a bloke at work. It was a Maclean, quite early I believe? Had four speed simplex, the one with the coil spring and little sturmey type chain pulling though. There were some wooden sprint rims as well, although I believe he kept them. I remember the frame being whippy, you could put your foot against bottom bracket and push it a long way! APPARENTLY this was a good thing, to aid sprinting!!!
Wish I had it now...
