@wawine, yeah, from your pic it looks like a 23". As @RobbieTunes notes, the Lotus Classique and Centurion Semipro are in the same league.
@nlerner, I'm riding 700c x 33.333's on my Classique, the vertical clearance on the fork blade just barely fits. I've got those same tires on my Zero Bike (Pro Tour), and they did ok going up Mt. Tam on Railroad Grade a few weeks ago with lots of ruts, exposed rocks and other crap.
@bikemig, if I can find a 24" Semi Pro or Classique, I'll buzz you about my 23" Classique...

Some years back I had the 25.5" Semi Pro in the orange color.
At the time with the available data it was thought to be a 1975.
I think I have a pic with the SN I can try to find for comparison.
It moved on to a new owner as it was tall for me.
I now have what I think is a 1980
23.5" Semi Pro in the yellow. It's a great riding bike and of course I love the way it looks.
Mine currently is sporting tires that measure 39mm wide on Hplus Son TB14 rims.

Here's a gratuitous photo for the Semi-Pro fans. This one is now in a new home with Tim in Virginia. A 1976 serial #, if I remember right.

There was also a later very dark blue that was just stunning with the chromed lugs.

The black chainrings and anodized bits on the Cyclone RD's on these are very sharp looking, with the blue and orange.

All the Centurion Semi-Pro data I've collected are for 1975-1981 models. The earliest reported Semi-Pro serial number that I've collected is M5B0040, There may have been some manufactured in late 1974 but they have yet to surface. on the forum (or I've missed them).
