New to me Centurion Semi-Pro

Earlier this week I spotted this intriguingly vague local CL listing.

Centurion Cycle Works bike - $XXX(Portage)

Centurion Cycle Works road bike, 56cm frame (or 21 inches), has 700x25 tires, SunTour Cyclone derailleurs, Cinelli handlebars and seat, DiaCompe Grand Comp brakes. Comes with a Zefal frame pump.
Bike is in excellent condition, weighs in at 21 lbs., and is made of steel, with chrome butted tubes.
Asking $XXX for this beautiful bike.


Hoping it was an Ironman I quickly shot off an email to the seller asking for pics and any other info he may have. Hours later I received 3 pics of a bike, but I still wasn't sure what it was. There was a Centurion badge but no decals. I was hoping it was an Ironman but quickly realized it was something altogether different. I then sent a PM to Robbietunes, our resident Centurion expert. He replied that he thought it was either a Semi-Pro or a Pro-Tour.

I then started a series of back and forth emails with the seller trying to get a time that he could show me the bike. Last evening we finally got together. After a quick look over of the bike and a short ride, moneys exchanged hands and I was heading home with this Pearl Yellow Semi-Pro.

The components on it very closely match the 1979 catalog. It is mostly stock but has had some tasteful upgrades. It currently sports a Cinelli stem and bars, a Unicanitor saddle, and Alfredo Binda toe straps.

Thanks for the help Robbie!

Here it is in "As Received" condition. Very little clean up will need to be done.

Robbietunes told me that the original decals were applied above the clear coat. I guess that implies that they either fell off, were removed, or a little of both.

Very nice! I inquired of this and the seller told me it was a Turbo. I was thinking it was a repaint due to the missing decals.

Brian, the seller mentioned your conversation of a possible repaint. I though so too but noticed the pin striping was the same as in some pics I had Googled.

Fantastic! Some of my favorite bicycles in history are Centurions from this era and slightly before. It's nice to see one of these in that yellow color!

I knew it! I was out very early this AM working and in a spare moment checked your thread with the 'teaser' pic, but as I was on my phone didn't reply. The chromed wraparound seatstay, same as the later Centurion Turbo, plus the Champion sticker, made me pretty sure it was that.

Great looking bike!

I'd like to clean it up but I don't want to damage the paint or the hand applied pin stripes.
I'm interested to see an answer to this, as I have the same issue on my Proteus frame.

I'd use something chemical, like OA, that doesn't require any abrasion to remove the rust. Honestly, I'd start even weaker and try some of your household vinegar (Acetic Acid) if you have some.

+1 household vinegar, in a paper towel, wrapped in plastic wrap to keep it from evaporating. Check every 12 hrs. It may be that this will remove some of the rust but only 'soften up' the rest. A gentle rub with a mild abrasive may take off the rest...maybe a polish like Mother's. Figure that you're going to have to touch up that area so it's not going to be perfect, but it'll end up under the clamp again. In general the paint looks fantastic. I'm not looking for another bike (and have a Turbo) but the orange version of the Semi-Pro would be really hard to resist.

Maybe try vinegar with foil first. May or may not be enough to take it off, but you won't do damage to the paint.

These older Japanese bikes, like some of Bianchi's Japanese-built models, looked great with that Gran-Compe brakeset highliting the Suntour derailers. Did the bke come with those Bindas?

I don't know exactly when the pin-striping came and went, and perhaps my '70's model had striped and decals removed?
I found this one on Craigslist right in my neighborhood, came with Dura-Ace and top-flight SR Bars, post and milled stem:

^^^Great looking bike. I love that color.^^^

I'm far from being a Centurion expert, but I don't believe that the earlier bikes had the pin stripes. And, based on the 1979 catalog, the font on the downtube decal and the badge on your bike are different than on mine.

And, the Binda straps were not OEM on this bike. It should have MKS straps.

My 1977 Pro Tour has nearly identical details, but the lugs and wraparound seat cluster aren't chromed. Funny, though, is that the chrome socks on the fork and stays go up about half-way, whereas on later models they painted them down to near the dropouts. My bike is NOT chromed under the paint.

My 1977 also doesn't have any pinstriping, but does (or did, rather) have the foil decals on the downtube, some of which I removed myself. Somewhere here on the internet there's a review of the '77 Pro Tour written by a young fella named Gary Fisher, who I think might have a future in the industry. my component codes were from late '76 and early '77, so this along with the review made it clear that mine was a '77.

Thank you for the tip on using Vinegar to help with the surface rust that I found under the top tube cable clips.
