Opened it up tonight, it's not too bad. Seat post and stem both came out no problem. Headset and BB are both out and did have grease - but I haven't cleaned and inspected them yet. Derailleur cables are I assume the original coiled stainless. Hopefully I can reuse them.
Seat post appears to be 26.0 - not marked but measures between 25.95 and 26.0. If anyone can confirm that it would be nice.
Supposed to warm up next week so hopefully I can get outside and wash and degrease.

Have always thought of these as Carrera Sport as well. In a recent forum thread a poster stated that there was also a model called simply Carerra.

Owned two or three of these and seen a number of others but have never seen one with a plate style chainstay bridge. Wonder if the bridge on this example might be an indication that it is a Carrera rather than a Carrera Sport. Not asserting such, just wondering; perhaps the ACER-MEX experts would care to comment.

Got one new about 1974 and it came with tubular wheels rather than wired-ons. Hubs were ordinary Sunshine 36 hole large flange qr. Rims were marked with a Windsor transfer.

In case you envision using a different stem for your planned build be advised that steerer takes an .833 size stem.

Here is photo showing the lugset employed to construct the frame -

http://bikeforums.net/attachment.php...hmentid=507716

seat lug was offered both malaguti style and "regular."

My favorite bike just happens to be a 'low-end' with chrome socks - my '75 Fuji S-10s. It just soaks up the bumps better than a tighter-geometry racing bike. Not that heavy, either, for being 'gas pipe' -- only 26.5lbs in stock form (and mine ain't stock no more ;) ) A well-tensioned set of light wheels/tires will make more difference in 'the ride' than a two-pound-lighter frameset! Go for it, and Enjoy The Ride!!!

^ my '78 s10-s was a lot heavier than that, even after taking off all the crap. a real tank.

it was a bigger frame too.

Weight for 23" frame is in '75 Fuji catalog

'78 listed the S-10S LTD at 26, and the 'regular' S10S at 27

I have stated this (and am NOT an Acer-Mex expert by any means) based on dimly remembered personal history: I convinced my brother-in-law to buy one of these when the brand first came into LBSes in SoCal and recall that his (red) did NOT have forged SunTour dropouts (just stamped steel plate) and the decals said simply "Carrera" but later offerings came with those DOs plus with "Sport" added. Still later the Carrera "line" seemed to grow to include some mor models and one had Tange tubing (tho probably something plain gage like Tange no.5) where these early frames were (IIRC) nothing with a tubing brandname and heavy enough to be lowly "gaspipe" steel.
I am not sure that the headlugs are actual Agrati (Bozzi) products but possibly Mexican-sourced copies since they certainly did not use the forkcrown, nor the Bb shell from Bozzi, and I'm doubtful about the seatlug, too. But juvela may know details here I'm unaware of.

And given my porous memory I would take ALL I write with a grain of salt. :)

BTW, that Windsor "Carrera" got stolen out of his garage within a year and he went on to ride different bikes (some much better, some not) in the ensuing years, we were both kind of glad that bike "went away" only cause there was some buyer's remorse after he took my un-earned advice.

Thanks very much for this response unworthy1; much appreciated! :thumb:

wrt the fork crown - wanted to post another image which shows these lugs loose with the crown used by A-M but could not find it. Will glue it in if am able to discover it once again...

The example under discussion is unique amongst the Carrera Sports we have had here at that forum, afaik, in having the reported plate style chainstay bridge. Wonder if perhaps this may mark it as quite early?

Thanks again.

Picture of the kick stand bracket. Frame with headset, fixed cup and short steel seatpost weighs 7.2 lb. Someone has painted all of the chrome including the cable guides and headset with clear coat that has yellowed and is flaking. I'll have to get some lacquer thinner and see if it will remove it.

Clear coat over paint and chrome (yellowing years later) wasn't that unusual, from what I've heard. PX-10s exhibit this "feature". I wouldn't be all that surprised if it was original (assuming the paint it also original).

So it's more or less finished. I think I need a new seat clamp, can't keep the nose of the saddle from drooping. Just been around the neighborhood, bike fits me very well.
Even the cranks and shifters were clear coated and flaking. Rear derailleur was more or less seized.
I was able to reuse all of the stainless coiled shifter and derailleur housing - sacrificed some shift housing to pull the liner out and use it in the old housing.
27.6 lbs

Very nice end result for a great looking frame. Don't be put off by the kick stand plate, I love these old low end bikes, the ones with character like these. If I were you I'd go for a simpler saddle that suited the era of the frame more, but whatever floats your boat!

I picked up a bunch of those demo saddles cheap from a store that was dropping WTB saddles. I use them for short term setting up new bikes. Figure they will get replaced if I decide the bike deserves the investment in a good saddle. Kind of sucks that a Brooks or equivalent can cost as much as the bike.

Congratulations on getting her all done, up and running! :thumb:

When seat clip plates get damaged splines their life can sometimes be extended by reversing the plates left side to right side and right to left.

You might wish to adjust the angle of the rear mech. Mounting instructions for it suggest to adjust so that pantograph assembly is parallel to chainstay.

Are brake hoods Modolo or a Modolo replica?

Ran across one of these frames at low cost on CL this week:

FIXIE ROAD BICYCLE FRAMES , Vintage lugged.

Wow, I thought my frame was rough - that is real ugly.
I'll adjust the derailleur. I adjusted the B screw to provide minimum gap at the large cog like you would a modern derailleur but you're right, it looks odd. This is the first time out of the basement so it's the first opportunity to stand back and look at the bike. I see the bars need to be rolled a tiny bit down.
The stainless coiled shifter housings were odd to work with, very floppy. Couldn't get them to the same level, I assume due to different cable tension.
The levers are just low end Shimano's with the original hoods from the local co-op.

Fine job. :)

Appears most of the fittings are what it would have come with ex-works.

Good work.

Just replace the seat clamp. They're only around $5.

Ah! I'm very glad to see this. :thumb: (apart from the saddle, but that's been covered already, I see). Now, how does it ride?

My advice: if you like a Brooks or equivalent, get one. Get a used one / old one if you can. I do, as long as they're in good condition, and generally pay €20-€50. They're permanently on my shopping list when I go to swap meets or cruise the classifieds. Just bought a second NOS "Donza" last Sunday for €20. :)

They last a lifetime if cared for, and fit on any bike. A worthwhile investment, IMO.
In the old days, the pros would change their bikes regularly, but they'd keep their saddles and handlebars. Just so you know. :50:

Bien sûr, mon ami! :)

Donza was a Belgian brand, that existed until 1981, if I'm not mistaken. Remnants of their stock still turn up every now and then. What I find after 35 years is thick and hard leather, so breaking them in will take a few miles. The one above I found last year, this is actually the one I found last Sunday. Paid €30, I think. Another '52', but without eyelets this time:

Donza made more modern stuff as well:

Grazie Mille Maestrissimo non-fixie! :thumb: :)

Senza eyelets must be the "52BIS" aka "Superleggero Modelo." ;)

That's a handsome late produzione Tecno Tubo Torino reggisella. Normally only see the early/ugly ones.

"Each time non-fixie visits the forum enlightenment occurs."

Got the small items fixed up. Embarrassed to see I had the seat clamp backwards - replaced it anyways.

Que Bueno! :thumb:

Even better :). Have you had a chance to take out yet?
