I have only made minimal changes to the set up. I changed the headset to a Campagnolo steel Pista model and the bars and stem to Cinelli model 18 steel pista bars and an older Cinelli steel badged stem. I also put new tubular tires on it. The rest of the componentry is a mixed bag of Nuovo Record and Super Record. Super Record pista cranks 170mm, Nuovo Record bottom bracket, Nuovo Record pista pedals with cyclo- cross toe clips and Alfredo Binda toe straps. Super Record seat post and Cinelli unicanitor wishbone rail saddle. Campagnolo low flange Nuovo Record pista hub set laced to NISI Moncalieri dark anodized rims. A Regina track chain rounds out the drive train.
The serial number is #11294 which puts it in the mid 1970's. There is also a stamp of 60P on the BB shell, which I assume is the size and model I.D. One odd thing is the BB shell has the "R" cut out, which is Rossin's logo. the company was sold to him in 1982 and he continued production into the 90's. So I am not sure if Sante actually made this bike, or if Rossin did. Also, maybe it is a transition period when Sante was showing him how to he built bikes. The seat lug has the "PSM" stamp, and other frame details which make me think Sante built this bike, but I will never know for sure. Any help from someone more in the know than myself?
The frame construction is top notch. Everything is filed and thinned nicely and the brazing is very clean. Classic Italian lines and styling. one nice detail is the drop outs. They are nicely filed into spear points where they are brazed into the fork blades and chain/seat stays. The flat fork crown is gorgeous and the large round fork blades are super strong. This bike retains all of its original decals and paint which is an added bonus. I am proud to be its care taker.
