I found this pair at a Garage sale. Both are Le mans RS models. Maybe 1984 vintage?? They are covered with many years of dust, but in real good shape underneath it.

The serial numbers:

N5G5764
N4P7406

Outstanding. Those are great bikes. Should be Suntour LePreel piggyback shifters, FD/RD, either 27" Ukai or 27" Araya on Suzue hubs, I think. Sakae bars and either SR or Sakae stem, same with seat posts. Diacompe stoppers. Probably the Anatomic saddles. I found my 58cm one of the smoothest bikes I've ever had, 56cm and I'd still have it. Single eyelets, clearance for fenders and racks. Great all-around platform: light enough to road out, smooth enough for light touring.

Thanks Robbie

The larger bike has been upgraded to a Sakae CX triple. They have 27x1 Araya rims. Did they originally come with 1" rims and 1" tires? These both have 1".

Another Centurion Dave Scott Ironman Expert

Hi folks,

I'm a newbie here ... came across this thread while researching this bike and its SunTour GPX group with an eye towards some repairs and updates.

I'm the original owner of this bike, purchased it in Colorado in the summer of 1989, or maybe it was 1988? It's served me very well indeed over all those years. These days its been relegated to the trainer with another modern day steel frame taking its place.

Serial Number: N9A5748.

It's mostly still original except for BB, some reworking of the cogset, pedals, stem, and a rear rim. I've been toying with upgrades for a bit now, but I can't decide if I should keep it as vintage as possible, or convert it into a rainy day bike with more modern components. Most of the components are in decent enough shape, as is the paint. The seat has to go though!

Best,
NS

Some of my favorite bikes in history are Centurions from this era and earlier. They really had a knack for useful and classy stuff in this time period.

EDIT: But not for the asking price! Yikes!

I wanted to show some of the progress I have made on my Elite RS this week,I got the wheels cleaned up and the hubs cleaned and repacked with fresh grease and new tires installed. BB cleaned and greased, crank cleaned and polished as well as the front and rear derailleurs.I have yet to decide what bars and stem I am going to run on it but I like this so far.

Finally got around to it. Here's some photos after a fresh coat of Turtlewax. Since my original post, I swapped out the freewheel with a Shimano that goes up to 28 (original was 24). Not sure if going up hills a little easier is worth not having the crisp, clean rear syncopation, given that the Shimano's gear spacing doesn't match the chain width or, in some spots, the Suntour index positions. I may put the original freewheel back on.

Why couldn't I find this thread last week.

Semi Pro looks sweet, I'll post up Serial numbers of the tiny Ironman I have for sale shortly. Guess I should also post the serial of the ironman I ride (powdercoated frame though)

Any ideas for where to find replacement graphics?

I read through most of this thread and what I found was people are tracing them and then having them reproduced at a decal shop or with a decal printer. Then they have to be carefully cut out...

This was for older models hopefully someone else knows where to get some Ironman decals.

I have this same bike (Elite RS in minty green with silver seat post and head tube), fitted it with gum wall tires (kevlar). Mine is a little too small (I'm 6'2"), the bike is right for a 6 footer or less. Mine still has the original white handle bar tape. Without a doubt, the best looking bike we own.

I bought my first Centurion, an Elite RS. It is in very good shape and according to Tmar’s serial# decoder, this bike frame was manufactured in 86. Although, the frame has an unusual manufacturer according to the same source.

"To date, I have received 19 samples that fit this format. All but one use "N" as the manufacturer indicator.” – Tmar

Serial # KA692520

This date is also backed up by the crank arm date codes of 85/Oct & 85/Nov.



Having acquired such a nice bike, it is ironic that 2 weeks later I found my second Elite RS at the dump. This one will require some serious attention. It dates to 85.

Serial # N5L7297

So was anyone able to date or identify this particular Centurion model? I just picked up the same bike yesterday afternoon and would like to find out what the heck I've got.

Serial number: 6R9960, located on lower seat tube, non-drive side.

AZORCH, as I stated in your orignal thread, I still think yours is a 1976 Super LeMans. Compare it against the pics of the Super LeMans in post #162 of this thread.

Hi,
Newcomer here. Rescued this bike from the scrappers truck yesterday. I believe it a Professional, Tange Champion #1 tubing. Suntour/Sekae/Sugino component mix. Looks like its all chromed under the black paint. No decals other than the faint remnant of the Professional and the Tange decals. Sweet bike, super light, but really little-maybe 49cm. Wish I was short. SN is M1A00752.
