centurion comp TA
 
I'm currently rebuilding a Centurion comp TA road bike. I will be more than glad to give my serial number for further information you may have to offer re:year made. It is great to have your knowledge available. This is my first rebuild and yes i'm a rookie at the road bike thing. I have the bike striped to the frame at this time. I will begin the surface prep next. I painted automobiles for several years for a local dealership and feel comfortable with the finishing phase of the build. I no longer paint cars for a living once I completed college years ago but painting is like "riding a bike" LOL. The bike is currently original and equipped with shimano 600 components. The frame has a good bit of scratches and surface rust, this is the reason for repainting it. The first question for anyone out there, Where can I find Centurion decals? It is (or seems) impossible to find on-line. Secondly, what is a good rebuild book?

It is late at night and T-mar I will get the serial number to you within the next couple of days. Thanks and have a pleasent week.

Rookie

First question, find mswantak in the BF directory, and ask him to help you out. I believe he's still doing it, but not sure. As far as a book on rebuilding, I can't help you there. Have you consulted Sheldon Brown's pages? Many questions you could address to people here or in the Mechanics forum. Good luck with the build, and take some before/after photos to post.

All the Comp TA that I've seen so far have been from 1984. It appears that it may have been a one year model.

Regarding the decals and re-build sources, I agree with peripatetic. I haven't used a book for that purpose in decades and really don't know what it is out there currently.

East Hill

Thxs. Yes, based on the serial number, the frame was built in 1980. The serial number is from early in the year, so 1980 is the likely the model year, though 1981 is an outside possibility. We can rule out 1990, as that is too modern for Vx derailleurs and 27" wheels. 1970 is eliminated because that was prior to the Centurion brand.

I'm not suprised there is no tubing decal. Given the year, it is likely hi-tensile tubing and it was fairly common to avoid putting tubing decals on lower end frames using this grade of steel.

T-Mar re:comp TA
 
The serial number on my bike is N4H5694. I want to say that one of Sheldon Brown's article stated the comp TA was made in the years of 84-86. "This bike was apparently sold under the Comp TA name only in 1984-86. WSI had to drop the Comp TA model name because Firestone Tires owned the name (a tire model). The Ironman model name replaced Comp TA". But, you have good hystory information thanks

p.s. What would you say the guess-ta-maded vaulue of this bike was new and if completely restored now?

Rookie

Well, you can't believe everything you read on the internet. I've done quite a bit of research on this brand and there a few errors in the article on Sheldon's site. For instance, the name conflict was with B.F. Goodrich, not Firestone. The author has been contacted and made of aware of this and several other errors.

As for the Comp TA being 1984-1986, that also appears to be incorrect. All the evidence points to the Comp TA being a one year model. For 1985, WSI contracted the use of the Dave Scott and Ironman names, introducing the Centurion Dave Scott Ironman model to replace the Comp TA. Sometimes it is refered to a the Centurion Ironman Dave Scott Signature model and various other permutations. The TA and Dave Scott Ironman were virtually identical, with the only significant difference being Tange#2 on the Comp TA and Tange #1 on the Dave Scott Ironman.

The Comp TA had an MSL of $465 US, while the 1985 Dave Scott Ironman sold for $479 US. Resale value will depend highly on the workmanship of the restoration, and market conditions, so it's almost impossible to predict. While it depends heavily on the amount of restoration required and how much of the work you can do yourself, my experience has been that it is very hard to recoup the investment in restoring a mid range bicycles, particularly Asian models with Asian components.

What's your opinion?
 
Do you feel that this bike is worth rebuilding or should I look into another model? I did not want to place alot of money into this until I understand and come to the conclusion I will make biking a major part of my frequent exercise routine. I est. I will have between 120-200 dollars invested once the project is complete.
Thanks again

Bicycles are a funny market. On the good models, many prospective buyers prefer the patina of a used, original finish over a perfect non-original finish. I'm not a very good judge when it comes to resale prices. Hopefully, some other memebers will voice their opinion.

RookieOnTheSeat 09-06-06 08:13 PM

no resale
 
this I will keep and ride:D

Cheapskate 09-08-06 12:07 AM

I have a 78 or 79 Centurion with serial number MF00201. I have no idea of the model name or tubing type. Details of the bike here and discussion about it in reply #13 and beyond of this thread. The discussion points to the tubing being one of the butted CrMo types.

1986 LeMans RS
 
Ok, here's mine. It's original parts from when I bought it new except for tires, brake pads, and chain (I still have the chain, but it's not working).

T-Mar, since you appear to be the Oracle of Centurion knowledge, can you tell me ANYTHING about these pedals? I love them, but I'm having the hardest time finding new toe clips for them! The ones I have were original, and NO ONE seems to stock anything like them anymore. I found one place that sold Campy ones, but they were also too small (the problem with these...they put my toe to sleep because they're too tight). What's the deal with these?

Also, if you want any more specific photos, feel free to let me know.

Wow, I finally got to ride this today after a month of refurbishing components. Not nearly as efficient as my Cervelo, but the ride is unbelievable in comparison. I'm inferring from T-mar's explanation that this is a 1980 with high tensile steel tubing. Mid-price point for its year model?

bigwoo 09-22-06 09:27 AM

Hi T-Mar, I found what I believe is one of the very early Centurions this morning at an auction and I grabbed it.
Although I believe that this Centurion Omega is not at the top of the pecking order, it has extremely fancy lugwork and bullet-point seatstays compared to my Sport DLX.
It has a nice metal head tube badge as well.
I'm guessing it's just Hi-Ten steel. R derailleur is a Shimano Tourney. Front is a Suntour 7. Dia-Compe drop forged center pull's.
Notre Dame fans would love it because it is an attractive all-emerald green w/ gold-leaf style lettering.

Serial #: IH28649I and is followed by the Omega-Centurion symbol

Do you need more photos than this one??

My guess is somewhere around 1972 **********

Katzenjammer 10-04-06 12:10 PM

Centurion LeMans Mixte (12 speed)
Serial Number N0D6xxx

SunTour kit, with stem-mounted "Power Shifters". RD stamped with what appears to be a sn

Diacompe centerpulls

Sugino chainwheel

Suzue hub

"27 x 1 1/4 w/o" Araya rims

Pedals stamped "MKS#QR-S2" and the wretched things must weigh two pounds all by themselves

cheesy-feeling aluminum handlebar with equally-cheesy "contoured" black plastic handgrips

the stem looks like a standard aluminum road stem, so the handlebars are actually lower than the elbow of the stem.

cheesy no-name leatherette sprung saddle

simple Dia 26.0mm straight seatpost

Deep metallic-ish blue with badly-done cream lug outlines and simple rust+offwhite pinstriping.

Decals are pinkish-white "Centurion" on the downtube and "Le Mans Mixte" on the chainstays. The typeface looks like a knockoff of ITC Eras. "Centurion" is in what looks like Extra Bold weight, and "Le Mans Mixte" in Medium weight.

Badge is round, cream-painted pot metal (or maybe aluminum) saying "Centurion Bicycle Works". Riveted on.

Sticker at the bottom of the seat tube says "Made in Japan".

It weighs 30 lbs (!!), per my balance-beam-type scale. Either it's made of gas-pipe or those pedals and the kickstand really add up.

So would it have been made in late Feb '80?

East Hill 10-15-06 01:17 PM

1986? Centurion Ironman Dave Scott Expert

http://s91.photobucket.com/albums/k3...gAnch=imgAnch3

Yes, just like my 1987 Nishiki Prestige, it has the smaller front wheel! Both wheels are Araya rims, the front wheel being 24" x 1", the rear being 700c.

Shimano 105 all around EXCEPT that a previous owner has removed the biopace chainrings, and replaced with Sakae 'SR 362' 42t and 'SR 307' 52t and a 175mm Sakae FX crank.

http://s91.photobucket.com/albums/k3...gAnch=imgAnch2

It also came with what would appear to have been an original Selle Italia Turbo 'Bernard Hinault' leather saddle--in black!

http://s91.photobucket.com/albums/k3...IMG_0331_2.jpg

Serial number is N6M8677.

Does anyone have any unwanted 24 inch wheels? I can see I need to lay up a stock of those as I keep finding bikes with the little front wheels.

Please note that this is NOT really a pink bike. As I live in the Pacific Northwest I am declaring this to be 'salmon' coloured.

In honour of Blue Order, it is now named 'Miami Vice'.:D

No pix unfortunately, but I'm sure you're right, that it is the same as yours except for the color and being a few months older. If you like I could copy your pic and P'shop the color :) (edit: hmmm...I'm sure you had a pic, didn't you?)

East Hill 10-21-06 06:56 AM

Thank you Katzenjammer. It sounds as if yours is a much prettier colour. However, I was curious about the poor job of outlining around the lugs, as the lugs on mine were fairly decently done.

http://s91.photobucket.com/albums/k3...Anch=imgAnch10

Edit to include pics.

East Hill

Katzenjammer 10-21-06 02:44 PM

I was surprised by the poor quality of the lug outlining too. It was definitely done by a different hand, not the one that did the pinstriping which was sketchy but clean. I'm wondering whether a previous owner tried to overpaint the outlining for some reason but didn't have sufficiently good control over the brush

East Hill

??? Did I miss something??? The two bicycles are seven model years apart. There's a huge difference between these two bicycles. Almost nothing is the same, except the brand name.

Katzenjammer's model is a 1980 LeMans. East Hill, your bicycle is the women's version of the 1987 Iron Man Expert. The 24" front wheel permitted a lower standover height for shorter riders. The color was aimed directly at the female market. Yes, it was built in 1986, but it is a 1987 model.

noisebeam 10-21-06 02:48 PM

T-Mar,
Is the LeMans in post #114 a 1984 year model as I figured from it's SN and your SN coding explaination?
Thanks-
Al

East Hill 10-21-06 05:13 PM

T-Mar, see my mixte post in #104. I am the proud owner of TWO Centurions--one, the 1980 mixte, and the other is the now properly dated 1987 Iron Man.

Ahhh, now I see! Thank-you for straightening me out. Sometimes, I need that. I didn't go back far enough, but then this post is getting rather lengthy.
