Dedacciai EOM 16.5?

[Dino Suegiù]

Has anyone here owned a frame built with Dedacciai EOM 16.5, in larger size, road frame, rim brake, carbon fork?
How would you characterize the ride, other impressions?
Was it stiff or forgiving? Robust or "fragile"? It seems described as fragile in some vague reports, and yet Zullo, Pinarello, Pegoretti, Casati, Olmo, Billato/Fondriest, etc all seem to have used it a lot.
What would be the comparative tubeset in Columbus?

[FlashUNC]

Closest would be something like True Temper S3 no?

Superlight steel and all that.

[Llewellyn]

I think my frame is made from this tubing and I've used both a carbon fork and, currently, a steel fork with it. It's slightly oversize and it's a great ride. I'm around 75kg and it's never felt fragile or "flimsy" and the ride is really comfy. Sorry if that's not all that helpful with your questions.

I do not know. I have never ridden a True Temper S3, which is why I asked for a comparison with Columbus tubing hopefully from someone who actually ridden the EOM 16.5. I have read that S3 is excellent, but I just have no basis to compare.

I had read some comments stating that the EOM 16.5 is fairly easily dented, but all those top thin wall steels are if abused, so I have no idea if the EOM was really any more fragile or not.

Since you like the EOM, what size is your frame +/-? How long ago was it built, that is your experience on it is long-standing?

I thought there would be more people with EOM frames and experience here for some reason.

I have also not really had luck finding out about the Zero 25

I think they are more popular in Europe as I have seen riding pics on IG all Euro based for the Zero25 frame.

My bike has the regular Dedacciai Zero tubing and it is wonderful. My frame was built by the late Roland Della Santa and it is just an amazing ride. I bought it used a few years ago and it is now my favorite riding bike. Definitely 4-5 lbs heavier than my Trek Madone 700 (840g frame) with Sram etap, but I enjoy the ride so much more. I don't know if it was Roland's magic or the DZ tubing or both, but I really enjoy riding this bike. If the frame fits, I say get it and enjoy!

Of course, YMMV!

Good Luck!

I have a Fondriest X Status that is constructed from EOM 16.50. I have had this particular bike longer than any other. It is that good. Not sure it's all the material but it certainly is a wonderful steel. Mine also has the carbon seatstays and a carbon fork. It is a 58 and I find it easily as stiff as my Merckx made from Columbus Zona. I am not a big guy, 160lb and not a masher so I can't speak to it being a sprinters delight, but it is very nice on a century ride. I would consider it a plus if is a frame that fits you. And if you get one and don't like it and it is 58ish let me know:)

It's a custom and it would be classed as a small, about a 50ST x 53.5TT (those are off the top of my head as I don't have the build sheet nearby). It bears my user name and was built by Dazza back in 2006. I think I have about 25,000km on it.

I liked the ride of both, although, the EOM 16.5 was a Pinarello with a rear carbon stay, and I found that rear was a bit flexy for me (or perhaps the wheel and stay combo was), and the front felt a bit more harsh in terms of transmitting impact. They did not all have the same fork though (but I did use the same wheels on them).

One S3 bike was a Kelly, and it had a nice smooth feel to it, and the type of low trail handling I liked, but I sold it because aesthetically I prefer a more level top tube and the Kelly was a very aggressively sloping TT design.

I believe the Waterford R33 was also S3, but am not 100% on that--but it was a great bike. Both S3 bikes felt smoother to me than the EOM 16.5. I sold the r33 to try carbon in circa 2007-8 if memory serves.

Of the light weight steel I've had over the years I think my fav ride was an Ellis I got here or across the hall (no idea on the tubing), 2008 SV road prototype (made by Sacha), then the Waterford R33, then IF XCR, then Pegoretti Responsorium, then Pegoretti Marcelo, then IF 953, then the Kelly S3, and then Pinarello EOM 16.5.

As for comparisons I've had some older steel, (not lightweight) such as my (collecting dust) '93 serotta coors light, 90's colnago masterlight, colnago olympic, ciocc, and a moser.

I also had a Kirk JKS, but am not sure that is considered lightweight, but it was a really smooth ride.

I now have a Kirk JKS 10th anniversary I got days before my cervical radiculopathy hit, which I've sadly never built up to ride. I suppose hope springs eternal, so I still have it too.

Oh, another "light" steel i had was a bianchi boron, but it was quite flexy--not recommended.

I tried a lot of bikes over the years, including some top carbon from Serotta (meivici), Time, Look, Colnago, Pinarello, Calfee, Crumpton. The only two I liked as much as the steel bikes were the Meivici and the Crumpton.

Good luck!

Super, thanks. That is very informative. Fondriest X Status are nice frames, and I'm looking at an EOM frameset almost that same size, also has the carbon seatstays.

+1. Very helpful.

Yes, I believe Waterford use True Temper primarily, including S3, maybe Reynolds as well, but not Italian steel afaik. Kelly and Waterford, both super.

Apparently earlier Pegoretti Marcelos utilized EOM 16.5, before the switch to Spirit; do you know which tubing yourMarcelo utilized? Pinarello and many other top Italian brands seem to have used EOM 16.5 as well, for years. I understand the carbon seatstays were an additional option Dedacciai provided to builders who wanted it, just as Columbus did with their carbon rear "kit".

What size was the Pinarello EOM 16.5 that you found flexible compared to TT-S3 and others, for what rider weight +/-? Too bad it landed at the bottom of a fairly long list.

If Llewellyn used EOM 16.5 and you have 25,000 km on yours (https://forums.thepaceline.net/images/icons/icon14.gif), that's a good sign, even if your frame size is at the other end of the spectrum from mine.

One thing I should mention is that my seat tube has a 30.6mm diameter which can limit your seatpost options. But I'm not sure if that was just a peculiarity of the tube that Dazza used or whether it was standard for that tubeset. But given the quality of the ride I can live with that particular quirk.

As I've said here a number of times it has been the best money I've spent on cycling gear. And with that in mind, the sun is out (for the time being) so I'm going for a quick ride before work kicks off this afternoon and a predicted thunderstorm rolls in.

Excellent, and your story now explains why the seat tube on the frame I am looking at has a carbon insert (I guess part of the carbon rear "kit" Deda supplied to builders) bonded in which reduces the seattube to 27.2mm.

Thank you for the specificity and enjoy your ride.
(And better thunderstorms than massive fires for all of you down there!)

I have a Pegoretti Marcelo made from EOM 16.5 that also has a carbon fork- first impressions were not what I thought. Having had a few carbon/aluminum bikes before it I was expecting that "springy" steel feel, but I was pretty surprised at how stiff and planted it felt. No problems with discomfort taking it out on all-day rides either.

Here is a recent picture of my X Status

I was not expecting to see that before I logged on, as most of the X-Status I have seen have a bit more exuberant swirley/fadey paint, a bit much for me.

Thanks for the compliment.
It originally had some type of black "rubber" paint on the steel. Over time it got sticky and everything would cling to it. I spent many hours removing it with certain chemicals and rubber gloves before sending it off to be painted. Had the carbon stays and fork painted to match.

My Ristretto (rim brake, carbon Enve 2.0 fork - 55cm TT) uses Deda 16.5 for the main triangle and Columbus XCr for the rear end. I am in awe of this frame, it feels wonderfully solid and alive at the same time.

I ride a 56cm, and weighed 165-168 for all these bikes. None of them were bad, but as you can see I have been lucky to ride some really really good bikes.

Honestly, I think the geometry as far as handling and the wheel/tire choice will do more for the ride feel than the type of steel in the tubes.

[PTinz]

am late to the conversation.

i'm 6'3" and 190 lbs. I have a Steelman Stage Race from 2005, Deda EOM 16.5 main tubes with a Deda Black Box carbon rear end (seat and chain stays). Reynolds Ouzo Pro fork. It is semi sloping and has a 58 cm TT (CtC). It is my second custom frame, behind an Columbus TSX frame from 1993.

Zero issues on denting. It went down once on the drivetrain side, high speed decent in the rain. Bent the hanger, but Brent had several extra and luckily it was replaceable.

bike has over 25K miles on it, and it is the benchmark for all other bikes I had/have. This frame will stay with me until the end I believe. It is 18.5 lbs built up with Record 10 speed and Fulcrum one wheels.

always been a fan of Fondriest frames, never had one though. If you pulled the trigger on a Deda frame, hope it is as good for you, as mine has been for me.

[colker]

Ibis was building w/ Deda 18mcdv6 in late 90s. I don´t where it falls in the hierarchy. Ibis went from tange prestige to that tubing.

[hnovack]

I had a Pinarello Opera with 16.5 steel, carbon fork and seat stays. Very comfortable bike, absorbed road shock well, not that stiff. The steel was also not easily dented. Enjoyed the bike, I have gotten shorter over the years and was too big when I sold it
