Killin' some time on the web I was reading a Sheldon Brown page written by T-Mar . I have read this page before but because this time I was looking at it for different info I noticed that the Comp TA was made in 84' and became the IM in 85' because of the copy right infringement lawsuit . I had always thought the Comp TA was a 85' . ?

Help

I am going to need some help. I had a 56 cm Miami Vice Ironman that was a little small. I let it go to a fellow BF member. I am supposed to get a 60 cm red and white Ironman frame. Question, should this be built as a Suntour (Arx) or Shimano 600 build to get as close to original as possible. I will provide pics and the serial number when it arrives in a week or so .

Very Excited to get on an Ironman that fits!!!

Your IM

If it's red&white 2tone, it would be an 86 with 600EX, or an 87 Expert with 105 (1050).

if it's red&white fade, it's an 88 Expert, would still be 105.

I have some more Ironman questions. I have been wanting another frame to put 10 speed components on and after a few adult beverages I bought one on E-bay last night. The add says its a 22" frame. The 89 I have measures 21 1/2. Did they offer them in one centimeter increments or are we measuring differently and they are the same size? It also has a Exage sport triple groupset. Were they available this way or has it been switched? It has everything but the wheels and I have two extra sets of ten speed wheels I can use. Does anyone know what BCD the crank should be. I would need the right chainrings if I used that crank with my wheels. I will get some 10 speed downtube shifters & chain and I have a triple 10 speed rear derailleur.

The Ironman was issued in even 2 centimeter increments, 46cm , 48cm, , etc. It was "basically" measured center of bottom bracket to top of top tube. The Ironman was Never issued with Exage components. Not sure of chainring compatibility.
Pics would be interesting.

I am guessing that its a 56 which should be fine for me. My 89 is 54 and sometimes feels like it could be a little bigger. I'll post some pictures when I get it. I may keep the triple but the rest of it will get a upgrade (or downgrade depending on how you look at it) I am thinking a sweet steel frame with modern drive train and maybe even carbon wheels would be about as good as it gets on a long ride.

Agreed, go for it.
​​​​​​​A drive side pic could help us determine what size you have.

Your 22 with Exage...

1-22" would be a 56 cm. Centurion measured from the center of
f the BB to the bottom of the scalloped side opening of the sets cluster, or pretty much c-top.

2-No way it came with Exage. Someone swapped it over, and there is a good chance that triple is a compact triple with 110 BCD.. The RSX triple (3x7 STI) is a compact 110 BCD and used a symmetrical bb, which is rsre. I think the Exage triple was also compact 110 BCD and may well use a symmetrical BB aldo, so it has value.

If you vlimb, that is a great group. If not, you are better off with a double, keeping that bb.

The frame is worth whatever you hang on it.

I like triples since I ride everything from pretty flat to lots of hills. We are wanting to do RAGBRI in 2019 and there is no telling what it will entail. My Origin8 has a triple with 53/39/30 and if I could duplicate that I would be a happy camper.

Here is the 88 Master E-bay bike. Its 56cm. I took the wheels off my 89 for a test ride. It came complete less wheels. I think the only original part on it is the headset and maybe the seat post.

@TXsailor: How's the handling with that angled shorty stem? I'm considering a shorter stem while my injured shoulder heals. I already switched from the long original to a shorter stem earlier this year, but after the injury in May it's been difficult to do more than 20-30 miles on the Ironman.

Main difference I've noticed with the slightly shorter stem (80mm CTC vs 115 for the original) is handling and balance are just a bit twitchier when I'm standing to pedal. I don't notice the difference on the indoor trainer, but off the bike I notice when I don't ride the Ironman outside often enough. Overall handling is still fine, though, and generally more comfortable before the shoulder injury.

With the long original stem handling is very stable, including fast curves and downhills, but I'm too stretched out. Might be better with aero bars.

I'm also pondering something like the Nitto Noodle drop bars, something with shorter reach across the bar top to the hoods, less drop, and a little less reach on the drops. But that's a more expensive solution.

c-cat,... Interesting topic.

On my 56cm frames, I run either a 70mm Cinelli or an 80mm modern stem, including a 56cm Ironman.
On my 54cm frames, I run a 90mm stem, including a 54cm Ironman.

To me, the 56cm bikes are more stable, even descending twisties.

Last weekend, on many curving descents, I had to focus harder to stay smooth and graceful on the 54cm Raleigh with a 90mm stem. One of my recurring thoughts was "I'd be carving this up on my Ironman." At the beginning of some descents, I felt like I was too far forward.

(On my 53cm Serotta, I run a 95mm stem, and it's still too short for my liking.)

I find it interesting. I'm not sure what seems to overrule what, as far as size vs. geometry vs. stem length. My 56cm Super Corsa, with a 90mm stem, was too twitchy to ride. The geometry had me "up on it" way more than I preferred.
