Full Bike

Tire Fit

I found this bike one morning near my house and figured I'd bring it home to work on it/restore it. But I have no idea what make/model/year it is and I come asking for help. I can make out the word "SINTESI" on the side but that's about it. I tried to take a picture of the brand marks that were still visible but mind you, none of these may be stock. Also I stuck a 700c wheel on it and I was wondering if it's too big?

    The crank reads "Sugiano GLP Special" and the stem end that holds the handlebar has "CB" inscribed on it. Jul 24, 2015 at 22:34
  • The wheel size looks spot on to me. Some road style bikes have minimal clearance above the tyre and the top of the fork. As long as the brake pads sit correctly on the rim and the wheel spins OK, I think you'll be fine. I presume it's been abandoned when you say you found it near your house, and that nobody is looking for it? :)

  • The front wheel does look a bit big compared to the rear, but I think this is because the front tire is fatter, and the rear tire is flat.

  • I would guess it's a bike from the early 80s. If so it's designed for 27" wheels and tires. 700C wheels and tires would be a hair on the small side. Jul 25, 2015 at 4:17

    Wait - You FOUND this bike near your house? Did it have a previous owner? Jul 25, 2015 at 10:20

Really hard to tell from the pictures. One thing I am certain of is that almost none of it is stock. A few observations:

  1. The main frame is lugged, has full length brake cable housing and horizontal dropouts and starred bottle braze-ons. All of those date it to sometime prior to the late 80s. Split brake cable housing on road bikes became the norm on production bikes in the late 80s. Horizontal dropouts also largely disappeared from mass production bikes due to the introduction of indexed shifting in the mid to late 80s.
  2. The fork is a unicrown model. Unicrown forks on massed produced road bikes didn't really become the norm until the early 90s. This one has a threaded headset so it mostly likely predates the late 90s by which time threadless became the norm on mass production bikes in the interest of cost savings.
  3. Sintesi is an Italian company who came on the scene in the early 90s and are still around though no longer in the US market (AFAIK). That said, "Sintesi" is also Italian for "synthesis" so it could simply be a model name rather than actual brand (for example, Irio Tommasini offers a model called the "Sintesi" but this isn't one of his)
  4. The stem is likely from the 70s. CB was a common brand back then. The brake levers likely say Universal, Weinmann or CLB. The exposed brake cable date them to prior to the late 80s at which point "aero" levers had become the norm.
  • Amazing you could determine all that by two pictures, I took a few more but it would only let me post two. Thanks for all the help everyone :) Jul 25, 2015 at 5:33
  • Way too many years working in shops, especially in the 80s! Also years spent working at centuries, races, etc. seeing all sorts of bikes.
