Centurion Master Ironman

Greetings from this newbie here. New to BF so please try not to bash me if I make a rookie mistake. Anyway, wanted to show my recent purchase and ask what some of you more knowledgeable individuals may know about it and maybe what it is worth. Any feedback is appreciated
I believe it is the 89 model from other pictures I have seen, all original Shimano 600 components it looks like. Everything BUT the saddle, bar tape, pedals and stem look original. Bought it for 190.
Again, any feedback would be appreciated, I will post pics.

Nice score for under $200. Tricolor Ultegra 600 is a big plus. Rims show no brake wear. Add a drop of WD40 on rusty spoke nipples/eyelets.. Overhaul it and enjoy.

Centurion...

Hi,

Single color throughout suggests '85 model. Google "Centurion: An Introduction" for more on color schemes. I should know this but haven't been paying attention for awhile. In Singapore at the moment so don't even have my own notes. Like all of the higher-end Centurions of the late '70s and '80s, a nice bike and a great one for the money. I've got six of them from the '80s.

There's an absolutely beautiful '80s Bianchi in Celest in a bike shop window a minute's walk from my friend's condo here. All that shining chrome... lugs, seat and chain stays and forks. It's been upgraded to Campy 18 speed and
sports a new Brooks Pro saddle. Alas and alack, too small for me. Looks just the same size as your Centurion though.

Singapore is getting bike-friendly in a hurry. I spend a couple of months here every year and I see lots more cyclists each year than I saw the year before. Singapore is a garden/park city and all is linked or being linked by a "park connector" route for pedestrians and cyclists. Great ride 'round the city state if you can take the tropical heat and humidity.

Good luck.

It looks nice. You did pretty good at $190 for that.

According to the Vintage Centurion website, this would definitely be a 1989 in Guards Red. Should be a Shimano 6400 SIS system.

Well worth $190 and welcome to the club!

Great score. That's definitely an 89 master, looks like a 56cm . You got a good one, congratulations and welcome to BF. It looks to be in very good condition. You were asking about how much it's worth. I'd say 350 to 400. Remember Centurion Ironman are priced low because of the quantity that were made not the quality. Those components are excellent and second to dura ace that year in the shimano line up. Those wheels are light and quick. If it fits you, ride it and you won't want to let it go.

Thanks, I will try the wd-40 on the spokes. Replacing the bar tape soon and will definitely enjoy the ride. Thanks again for the feedback

Wow I definitely feel like I made a good call now with all of the positive feedback. Another quick question sorry, but, would an 89 Master (in white with the black/smoke/marble fork) in similar conditions to mine be valued the same if it does not have the Shimano600 RD? It has the 105 RD but everything else is 600 (crank, brakes, etc.) I guess a better question would be, if the 600 RD was swapped for a 105 RD does it drop the value a lot?

IMHO Shimano 105 is higher quality than Shimano 600 and, should be considered an upgrade. An 89 Ironman Master is a desirable bike. They quit making the Centurion line at some point in time right around 89 -90 - 91 (I'm not entirely sure when). The last models they made were very nice. The Ironman line began to sport Shimano 105 components. Soon after, most Japanese bike manufacturing was transfered to Taiwan. If I'm not mistaken the Centurion bike line was replaced by a bike called the Diamond Back. But, someone else here probably knows more about that than me.

FWIW:
Shimano 600 evolved into Ultegra.
Shimano 105 evolved into....... well 105. It is a successor to Golden Arrow.

i semi agree with Ramzilla i think the 2nd Gen 105 that was introduced in 1987 and was on the Ironman Expert was better than the 600 SIS, but in 1988 when 600 Ultegra came out i think it was a nicer grouppo.

Now not having the 600 Rear Deraileur is not a big deal as the 105 was really good as well. I think you have a great score as well.

FWIW the Ironman was made from 1985-1989 (WSI was the parent company) in 1990 WSI dropped the Centurion brand and moved the road bikes over to their other brand that they had Diamond Back, which until then was only Mtn Bikes and BMX/Freestyle bikes. So your 1989 was the last year of the Centurion Name and the Ironman's

As I remember, the 1987 105 equipped expert Ironman had the first year 105. It was comparable to the 86 & 87 600, but not as good. However per value it was better as it mimicked 600 in both appearance and function very well, which I would guess is why 600 became ultegra. But better? No.
I currently have the 105, 600, and tri color 600, and they're all pretty good. They get a touch smoother shifting going thru the ranks but 105 is the best value in my experience.

you are correct 1987 was the first year of the New 105, There was a previous generation 105 called Golden Arrow. The biggest difference to me and what makes the 1987 105 Better than the 1987 Shimano 600, was the SLR Brakes. as 1987 600 SIS did not have it, it wasnt til 1988 when 600 Ultegra came out that 600 got SLR Brakes. and it was 7 speed compared to the 6 speed of 105. which got 7 speed in 1989 (I believe) The color of the 600 Ultegra (Tri Color) was the last thing, as it was so different from anything else out there it seemed ahead of its time.

And yes 105 was and i think still is a great groupset with the most bang for the buck!
