Look what I found yesterday! Needs the little work on the seat. It is all original except the rear tire. It was a one owner bike bought new in LA. It has one spot of clear coat peal and a couple little paint scratches, but really it has super nice paint still.



What do you think? I am now have an 1988 master and an 1989 expert...

Congratulations on a heck of an acquisition. Looks really clean. Is that a avenir sticker on the top tube?

Yes, that is the CL bike. It was only like 8 minutes from my office, so it was an easy one to go see.

Do you have a speculation as to why some 89s have avenir stickers and some don't? I know Dave Scott was sponsored by avenir. Was it some subsidiary of Centurion?

This bike also has a non-fluted SR Sakae seat post and I believe it should be fluted. The previous owner insisted that is the bike is exactly the way he purchases it, except the back tire, but the seat post must have switched at some point along the way.

Im pretty sure they stopped the fluted seatpost after 87 (thank goodness).
But it's odd to me how some 89s have the avenir sticker and others dont. What is your serial number? Perhaps later models have the stickers.

I think the seat post should have the light/shallow and short fluting at the top of the post.

I think Avenir became a house brand for WSI, because starting in the 1989 sometime they started to use the Avenir logo on the Diamond backs and the Centurions. I think maybe WSI had bought Avenir around that time.

So i agree it may have been a mid year thing, my Black dog does not have the Avenir logo on it but my 1989 Diamond back Apex has it and a 1989 Diamond back Ascent Ex, i just got done with refurbing for the coop has it.

According to the IM Spreadsheet,
1985-1987 Scaled Seatpost
1988 non fluted/non scaled Seatpost
1989 Fluted Seatpost

the 1989 Expert should have "SR Laprade fluted 27.2"

My '89 Ironman Expert has a fluted LaPrade seat post. Not sure what the purpose is for the fluting. It's above where the seat post is clamped. Maybe a design conceit of that era, similar to the fluting of revolver cylinders to shave off a tiny bit of weight. Makes sense for short barrel hideout guns, but not much sense for heavier frame large caliber revolvers (although it may relieve some stress on cylinder stops by minimizing rotating weight). But that design conceit dominated regardless of function.

I agree. My 1990 DB Centurion Master has it too:

Using [MENTION=20650]T-Mar[/MENTION] SN deciphering for Frame serialization we can see the following for these Black Dog IM's

N9G5570
SJStretch 89 is a week 13-14 of 1989 or first two weeks of April 1989

N8M6817
Mine does not have the Avenir logo and is a week 25-26 of 1988 or first two weeks of July 1988

since mine is a earlier 1989 model it does not have it, so it maybe started in Fiscal year 1989? we need more SN's on them to help narrow it down.

Do you know if they continued the avenir sticker in 1990 on the centurion/diamond backs?

I fixed that issue.
The calipers should not do that. Similar issues with 105's. I'll send you the steps.

And I need to tug the rear brake cable housing back into position if I let the handlebar flop during a stop, especially if it flops to the right. It tugs the cable housing about 1/8"-1/4", just enough to make the right rear pad rub. Usually I don't notice over normal wind noise.

But after riding 10 miles in the rain Saturday I noticed the rims were coated in a white powdery residue. This exaggerated the noise of any pad rubbing on the rear wheel.

Reminds me, I need to zip tie the rear brake cable housing as well. One less thing to worry about while riding.

Thanks, got it. I ask because of my 89 Summertime Blues Ironman. The general consensus is that it was gonna be a color scheme for the 1990 model had it continued, however it doesn't have the avenir sticker.

Speaking of my Summertime Blues Ironman, It's been hanging in my house for over four weeks. I'm waiting on a vintage NOS part I ordered from eebay from another country.

I bought a new cheap chain for my Classic, hopefully that will solve the grinding issue. If not I'll have to install another BB. Speaking of my Classic, sans grinding feeling and noise I love that bike. It shifts solidly, rides comfortably, and the bike I would choose to ride across the country on. If I were to find another one in the same size but in excellent condition I'd have to pass on it because my 86 classic is very dear to my heart and why the grinding feeling of the drive train is so upsetting. Of all my Ironman it is in cosmetically the worst shape (now that I've replaced my Miami Vice with another exact size better condition Miami Vice), but since it's been clear coated it shines like brand new.

Speaking of my Miami Vice, I've been riding it the most in preparation for a couple of multiple sport races I have coming up. One next weekend is a short sprint triathlon the other at the end of the month is a run bike run duathlon. I've made a point of comparing it to my 86 Classic because they're the same size and setup the same. The number one difference is the components. My Classic has era correct Dura ace and the Miami Vice has completely stock 105. The dura ace has a more solid feel when shifting the index shifters and the Miami Vice has a louder humming/buzzing sound when pedaling at a good steady clip. But other than that the ride is pretty much the same. Those original 105 are hard to beat. I remember back in the day how I would judge whether someone was serious about riding or not based on their bike; eyelets,FD tab, and components dura ace campagnolo or not. Suffice it to say I know better now.

I'll be installing walmart chain later today then go on a 25 mile ride on my Classic. If the new chain solves the grind issue I'll buy a better one for my Classic. Later Irongents and keep the rubber side down.

Update, my 86 Classic is saved.
After overhauling, BB,HS,freewheel,hubs, and greasing stem,seatpost, and tightening saddle,skeweres,and replacing pedals,cables,and cleaning and lubing chain. I finally found what was causing the grinding feeling/noise. I replaced the chain with a new cheap one and that was it. Whew that was a beach going thru all that. Anxiety more than anything. Who would have thunk it? Certainly not I. I measured chain and it did need to be replaced but for it to do that really threw me off. I suspect when I would really mash on it is when the chain would stretch more and "grind" against the chainring and give the illusion that it was the BOTTOM BRACKET. Geez Loweez guys, later.

Which chain was making that grinding noise?

My Ironman came with the original Suntour chain. It wasn't too badly worn and stretched but was noisy in the 42/24 gear combo. Replacing it with a new KMC Z72 solved that problem. (And using wax instead of oil dampened any sound even more effectively.)

Before replacing the chain I'd tried adjusting the rear derailer a little on every ride, but only accomplished messing up shifting all around. When everything was set up for the smoothest, quickest and quietest overall shifting, it was a bit noisy in the 42/24 combo.

My theory is that the Ironman wasn't set up to be used much in anything resembling a mountain climbing or granny gear. There's a noticeable angle along the chain in the smallest chain ring and largest freewheel cog, verging on what would be cross chaining in another bike -- I hear similar noise with my Univega Via Carisma in the middle 40T chain ring and either of the largest cassette cogs. Just enough that I can hear the chain noise even with a new chain. As soon as I'm in the middle cogs the drivetrain is quiet.

FWIW, the KMC Z72 isn't the quietest chain I've used. I think the mushroomed rivets make a bit more noise than peened plain rivets at the more extreme angles. Just a theory but the slight overlap of the peened mushroom heads may slightly rub the outside of the link plates. The plain rivets on my other KMC and Shimano chains seem a bit quieter, but those are on my other bikes so it's hard to compare.

The chain was not original to Ironman. In fact most everything on it is not original however it is period correct Dura Ace. I believe I installed a Shimano UG 50 maybe.
The new chain is a bell from walmart and very quiet. I've been looking on eebay for a dura ace 6 speed compatible chain with no luck. Well other than a used one, but I'd settle for another ug 50. I like the vintage shimano chains as they tend to stay lubricated longer.

My experience with chains is limited to shimano dura ace, 600, UG 50?, and Regina hollow pin. This is my first time with the bell/walmart and a clip in plate.
