1970's Guerciotti ID

I just picked up a 58 cm Guerciotti road bike in what appears to be original condition. Unfortunately I am finding it hard to put a date on it. There is no tubing sticker. It is set up as a 12 speed with Nuovo Record derailleurs. The RD has "Patent 70" on it. The campy cranks have "170 strada" on them and a little square with an "11" in it. The bottom bracket shell has two cutouts. The brake levers have a minimal bit of drillium. The shoes and the brakes are campy aswell.it has a cineli 70 mms stem, Cineli grand criterion handlebars, a turbo saddle. The wheelset is campy record hubs on mavic Ma40 rims. Every bit on the bike says campy (can't find it on the seat post) down to the pedals and binder bolt. The 6 speed freewheeling is a shimano. Could it be possible that this bike was originally a 10 speed? I read that the older Guerciotti bikes came to the US. Unpainted and were sold as ten speeds.

The bikes appears to be well used but still in good shape. With minimal spots of rust. I bought this bike for my personal enjoyment and because I miss having a vintage bike since I sold my Merckx some years back. If anyone has any information on identifying this particular model, year, history, tubing, value, amusing anecdotes.... please let me know. I am very excited about this old bike. Ill add more pictures. Thanks in advance!

Based off the decals it's a mid to late 80's TSD bike. TSD (Ten Speed Drive imports) was the importer and distributor of Geurciotti's, That big star on the decals is very indicative of a TSD bike. I believe the square 11 is 1984 in Campy speak.

Do you have pictures of the brake bridge and fork crown? That's an American Classic seat post.

But it could be older, the 3 I owned all had braze-on front derailleurs.

This is a typical TSD brake bridge:

Here are some more pictures. The rear brake bridge is a much simpler design. The front fork transitions seamlessly from the crown. The brakes also don't have a counter sunk Allen head like on a lot of 80's bikes that I've seen.

I wonder why the crank is an 84 and the RD says "patent 70"

Or its a older early 70's model that has been repainted and redecaled. The components could easily be a mix of on hand stuff if the frame was purchased as a frame only.

Is it even a Guerciotti? Shouldn't a Guerciotti have a star cutout on the BB, pant'od seat stay caps and embossed fork crowns?

The images are not the best to evaluate fully. I have seen that bottom bracket cutout before... But as it is most likely a repaint, I think the fork may not be original. The graphics are 80's the frame details are not.
It does not look like a Guch' to me yet.

I agree...it does not look like a Guch to me either...those bottom bracket cut outs...I have seen...but...do not associate with a Guch...the star is the thing for them. Also...didn't most Guch's have "Guerciotti" embossed on the top of the seat stays? I seem to recall that as well...

I was afraid that it might be a restart. Upon closer inspection the decals are not under a clear coat. That being said can anyone identify the frame? I still like the bike. Now I am less worried about keeping it original. I still plan on riding the heck out of it.

*respray.

I think I might have figured it out. Thanks to photos from classic rendezvous. They have a couple pictures of "jack bissell's guerciotti." The frames are identical except for the cable guides. There is no picture of a bottom bracket cutout but everything else seems to check out.

The long point lugs sure look the same. The fork is definitely wrong but could very well be a replacement done at the time of the repaint along with the brazed on cable guides.

Can you remove the water bottle cage and get a photo of the braze on mounts? The ones on the Guerc on CR were quite distinctive.

The fork is definitely not original. The working theory so far is that at some point during the 1980's the bike got a new crank, paint job and fork.

The bike seems to be in the transition between jack's and this one.

Here is a picture of the water bottle studs

Does anyone know where I can find an old guerciotti fork?

I recently got a very nice Guerciotti bike setup with dura ace components and matrix iso c-11 heat treated profile rims. The hutchinson fusion comp yellow tires look great with this bikes cosmetics and also ride pretty nice. Really happy with how nice it rides, pretty similar to my colnago and masi columbus slx frames.

This model has no frame sticker for the steel. Suspect its also columbus tubing ?
Anyone have more info on this model ?
The frame quality is top notch and the chrome forks and chrome tube areas are also impressive.

Not much info on the net about Guerciotti bikes.
Similar to a few model photos from classic rendezvous site.

Joesch,based on the chromed fork, chromed chainstays and front derailleur hanger, its probably the SLX tubed GLX model. However, to be sure, you'd need to remove the bottom bracket and check inside the ends of the tubes for helical ridges.

Thanks for your response which helped me find this thread:
1984 Guerciotti GLX Build Recommendations
The BB cutouts are parallel slits rather than the larger star that is shown on the above frame but otherwise looks to be the same frame.

I've never seen a GLX with a bottom bracket as you describe. You should post pictures of your bicycle.

I posted pics of my GSX with dura ace at https://www.bikeforums.net/classic-v...ciotti-id.html

Does not show the BB but the other pics are very revealing ...
