Pinarello Opera Frame Weight and other steel bike weights(11 posts)

Pinarello Opera Frame Weight and other steel bike weightsJcamelback

Is the advertised weight of the Pinarello Opera a 56 cm bike at 2.80 lbs legitimate? A guy at realitybikes.com told me the weight is more like 3.8 lbs, that's a big difference. Do other steel bike manufacturers lie about their frame weights or are the hig end steel bikes really lite?

anyways i would add at least 5% to anyone's weight claims. 1 pound does seem a bit much as pinarello would have all sorts of legal problems if it were true.

Thanks. He claimed that the frame alone for a 57cm weighed about 3.8 lbs whereas Pinarello claims that a 56cm frame alone weighs just 2.80 lbs. In addition, on another thread on this website under "components" and a discussion of Ciocc framesets, some guy who I believe works for Anvil Bikes claims that Pegoretti's advertised weight of about 2.8 lbs for the GGM frame is bogus. He says that the Great Googoolee Moogoolee frame alone (without fork) for a 58cm size weighs much closer to 4lbs than the advertised 2.8 lbs for a size 57.

It would be nice to know who is and who isn't correct. Has anyone actually weighed any of these frames independent of the manufacturer? What would be the purpose of paying out bigtime cash for a Dedacciai EOM 16.5 steel frame if the thing weighed almost 4lbs for a size 58 frame alone? I could get a low or mid level lugged steel frame bike in that weight range for much less dollars.

get an independant weight and send the results to whoever the frame manu. is and ask them what the deal is.

1.2 pounds is a lot of diff. for a frame weight alone and if your "guy" at anvil is just talking turkey im sure the people at pegoretti would be interested.

i noticed a googooleee 55.5 at gvh bikes and gary offers good prices on them if you inquire. maybe give gary a call and ask him what the real deal is - he's an honest guy .

i would be surprised if "anvil bikes emplyee's" argument holds as its pretty hard for frame manufacturers to disguise and fiddle with such weight disparity especially if they make official claims.

then again mavic do it all the time....

I would be willing to bet that all of the high end steel frames (853, ultra foco, EOM16.5) are within a 1.5lb range of each other(same size). I stopped getting hung up on steel frameset weights, I think it is going to come down to geometry and how the frame performs that will make the difference in steel frames. I understand your point, however, big bucks on a steel frame does not equate into big weight savings. Look for a different frame material if you want lightness. I am looking at Pegoretti, F.Moser, Scarfacci for steel with a stiffer BB than my 853 ride.

I think you're misquoting me. If you read the thread, Istated that I was told, by someone who has been shopping for one, that the Pegerotti GGM frame weighed closer to 4-pounds for a 58. This makes sense to me given the huge tubes on the GGM and the knowledge that you can only make the tube walls so thin. Though I've never weighed one, the Pinner could well weigh 2.8 pounds, it's built with more conventional EOM tubes.

Let me put this another way. Frame manufacturer's advertise frame weights based on a single frame size. I have no idea what size frame Peg used for weighing purposes but it is physically impossible to use the size tubes Peg uses for the GGM and build a sub 3-pound frame in any reasonable size unless it is built unusually thin walled, straight gauge tubing. Perhaps it is, but if that is the case, then the bike would be very fragile. There are some folks who ride Pegs on this board, maybe one of them will have first hand knowledge of the frame's weight.

I can't confirm or deny, but I will tell you that the weight the 2.8lbs is for the frame only. I have held the frame and it's pretty darn light. Didn't feel heavy at all. The weight felt like an aluminum frame. I should go back to the bike store since they have a scale and I could request to weigh it. I'm sure it would come in at less than 3lbs.

Remember that Pinarello uses Dedacciai EOM 16.5 steel tubing. That's pretty light tubing comparable to Columbus Foco tubing.

OK I got an OPERA abaout 2 weeks ago! And I'd say 2.8 is right. Damn it's light AND BEAUTIFUL too. Somebody said it feels as light as an aluminum frame and they are absolutely right. I had a cannondale caad4 a few years ago and thats the first thing I thought of when I lifted the new Opera. Light as a Cannondale no doubt.

Some mfr's will either post the weight of a smaller than avg frame or a frame before it is painted. 3.8 lbs sounds pretty heavy my old school Gios chromed lugs and all weighs a little over 4lbs if I remember right (52 cm). Around 3 lbs sounds about right for a lightweight steel bike.

A 56 is not 3.8 lbs. I have a 58 that is lighter than that. I would guess that a 56 would weigh around 3.2 or a little lighter.
