Bottom bracket second digit is a 5, so 1985?

I've never seen one this color before, the ad for it made it look black, but when I pulled up and saw it matched my dark shadow grey harley truck I had to take it home with me. It doesn't hurt that it fits pretty good and all the components (shimano 600) are working perfectly!







Frame is roughly a 25". It's incredibly light for a steel bike to me.

The seller was the 2nd owner, bought it in 1989 and did tri's with it, he gave me the original drop bars, a spare tube, a presta valve pressure gauge, and the tool to remove the freewheel which I'm going to do later today as I clean it up.

gorgeous bike. congrats!

Could be 1984 to 1986 area. Centurion made it in red and also your silver. They were beautifully built bikes and I think that they are very underappreciated.

That should go in the general C&V forum, where there is a LOT of Centurion and particularly Ironman love.

Most prominently this thread:

Nice bike, btw...the earlier ones seem to be less common, maybe because the model was so successful they ramped up production later on.

Awesome. Get rid of those bars. Lol.

Alan Edwards

Keep the bars they are vary hard to find and work great for TRI's. Look for a Nitto stem, that was the original stem. If your just going to use it for road riding changing the bar will make it easier to use but don't lose that scott bar.

realestvin7

Then you can buy mine. Lol.

What about those brake levers? They look sketchy to me.

Roger M

The levers are just upside down. Get some gum hoods for them and mount them rightside up on the correct drop bars and you'll be good to go.

Beautiful bike. looks like about a 60cm?

I have the same model, and probably same year. 1985. They're nice bicycles. The Ironman expert should chime in at some point, to give you any information that you need on them.

other than the bars, pedals, and tires, the seller mentioned to me that he changed the chainrings out to get more speed. The large ring is a 52t! It has a shimano bio-pace label on it.

I think the size is closer to a 62cm.

I forgot to mention he also threw in that nifty kickstand the bike is sitting on in the pics, it supports the bottom bracket and has a hook to the down tube, very easy to prop it up and take it off the bike, it lifts the rear tire enough to tune the derailleurs.


I posted this in the value forum as I was curious how well I did. I paid $120 for the bike.

I'll have to look for a nitto stem, I'm not opposed to the one currently on the bike as I'm more used to my 68cm bike and I'm tall (6'5") but having the original parts for the bike would be nice.

and the stem too. put a nice stem and drops on that...

the rest of it is pretty nice though, good score..

1985 model. Very hard to find.
Shimano 600EX was the original equipment front to rear.
OEM stem was a Nitto, bars were Nitto B115's.
Rims were Araya red label, saddle was a Turbo.
Welcome to the forum, glad to have you here.

There is a Centurion Serial No. thread on this forum, plenty of Ironman fans.
Any questions, feel free to ask.

Sweet find and a Sweet bike.

Very well.

Blind

what should I look for when going after a replacement stem to be more original? I see lots of different angles and lengths on ebay where I'm looking to get an idea.

I believe the drop bars the seller gave me with the bike are the original nitto b115's, the rims are red label araya, the saddle is an avenir 'gel comp' according to the label on the back of it.

I'll have to post the serial # up on that thread once I find it, thank you

Robbie can tell you what kind of stem was original, but as far as length goes, the right one is the one that makes the bike fit you.

RobbieTunes

What he said. The OEM stem just said "NITTO" on the side, so if you go for one, get the one that fits.

frantik

surely you meant the Ironman MASTER

you could sell it for 300-400, if that gives you an idea. you've got the pimp colors from that year (85)

are those the original chain rings? I have shimano 600 rings (both Biopace and round) but they are not anodized like on that bike

RobbieTunes

Those are the OEM chain rings. Anodized brown on the '85 model, same as the '84 Comp TA

frantik

yeah i saw more in the post your IM thread.. me want

Blind

so I swapped over the OE nitto drop bar last night, but really am having trouble finding a set of hoods that will work on the OE shimano 600 brake levers.

Are they compatible with 'aero' hoods, and does anyone have any detail on how the brake cables should be routed with the new hoods for me to go off of?

My other road bike doesn't have hoods and the brake cables just stick straight out of the tops, so I don't have much to go by when setting up this bike.

BRAZUCA

Very nice bike, I want one to match my Elite RS! Perhaps I will find one next year! (Suddenly I became a Centurion fan). Congrats.

RFC

+1 Yes, hold on to the bars. They were a major jump in innovaton. You can find the reports from the first Ironman Triathlon where aerobars were used by the winner who simply ran away from the pack during the cycling stage.

RobbieTunes

The hoods are available, and out there. It's been so long since I needed any, I've not looked in a while.
