Welcome aboard Dave!

I took the opportunity to go look at your pics and lo and behold, an actual pic of the famous yet illusive ti lugged Pino bike!? Do you know what happened to that bike? It would be fun to track that down and get more shots of details... I would like, with your permission, to add that pic & letter to the Pino section in the CR site.

Hello from sunny New Mexico, the Land of Entrapment. I saw your list today (blame Peter Weigle) and had to join after Dale set me straight on the how to. I'm a nearly 40 year veteran of frame building and an ex-bike shop owner (good riddance retail!) I hope that after reading the rules I can behave myself and stay abreast of the classic stuff you all enjoy. I only have one classic bike, a 1927 BSA which belonged to Franco Georgetti and was raced at Madison Square Garden in the 20's. I was very close to Pino Morroni for many years and miss him dearly. We shared many secrets and both had O.S.C.A. (Maseratti) powered race cars. My frames have garnered over 150 National records and a couple world records. One has held the National 40K TT for nearly 20 years (47:35- John Frey) I had a bill passed in NM which allows true pari-mutuel style Keirin racing, but the Feds have us stymied due to the Professional and Amateur Sports Protection Act. Long story, it's somewhere in the blog if you're bored some day... I'm married, have two Rottweiler's and am 58 years old. I was badly burned in a shop fire here in 2007 and lost an eye. I'm 95% recovered and back to work full time. I mostly restore old foreign sports cars from the 50's-60's. Hope I can add to the mix and I'll keep my politics on my blog Comments and questions welcomed. Cheers, Dave

This blue, yellow, and chrome italian bike (BICI DA CORSA MUCELLI) has a 2-cog freewheel (almost like a tandem stoker gear) embedded in the right chainstay, which splits into 2 parallel plates and back at the midpoint.

I can imagine that, although it presently uses the same number (28:28?) of teeth for the 2-speed freewheel, it was probably designed to be used with either a 2:1 or 1:2 gear, maybe 14-28 or 28-14, so that you could have a tremendously low or tremendously high 5-speed geartrain on the bike.

The bike appears to be 52T front and 14-26T in the rear (roughly). That would be a 54-100 gear, in inches. With a change of 'stoker' cogs, you might get 26-50 gear inches, or 108-200 gear inches, and the later would be unheard of, on all but bonneville land-speed record bikes. Those land-speed record bikes have a similar drivetrain, and I have seen them put the reduction gear up by the seat cluster.
