I think this could be considered not off-topic:

What would be the point or the steels that marked the end of the period of classic steel frames, materials wise?

So, for example, is Reynolds 853 or Columbus SLX a modern alloy? Or is there such a thing?

If you're thinking about buying a frame and want to know if it's a decent weight then none of the above comments will be of use unless you know whether it is frame only, frame and fork (frameset), or frame and fork already with headset (and possibly bottom bracket too).

Feck me, thats light.

(Planet-X Titanium pro road - (size L) - 1389g
Ridley Noah carbon - (size M, IST) - 1200g)

Yes, very light (especially for a 58cm) Might be 'interesting' to actually ride.

The expression noodle bike comes to mind.

Adscan, are you looking at a particular Red 3.2kg track frame on ebay?

Weight: 9.85 lbs( frame, fork bbset & headset)

Frame Weight: 7.45lbs.

3.38 Kg !!!!!
Good job its red, otherwise it might be slow as...

Sorry, but very new to the ss world, but what weight is considered a heavy SS, and what bike weight would you aim for when building a bike? Or don't you guys really care how much the bike weighs?

I'm shopping around for an OTP SS/fixed and am struggling to find weights on most of the specs online... Kinda like the Kona Band Wagon, the Felt District, and the Charge Plug, but can't find weights for any of them, other than people saying that the Charge is heavy, but no idea what that's compared to?

Any thoughts on those bikes and advice on weights and things would be amazing!! So knew i can't even start my own thread!! :(

that was supposed to be "new", not "knew"....

Around 8 kilos is ok I'd guess

TBG, don't worry about the weight, just test ride a lots of SS bikes and choose the one that you like the best out of ride quality.

Weight makes fuck all of a difference. Get a bike that is comfortable and rides well. If it happens to be light too, then so be it.

Weight makes - for me at least - the greatest difference when riding a bike - I am more than sure it will differ for the individual, but depending on your riding style, how you throw a bike around and so on, getting on a super light bike can be revelatory.

Going fixed, although something of a milestone for me - simply does not compare to changing from a 30lb bike to a 13lb bike. - If I were to give up either riding fixed or riding a super lightweight bike, it would fixed that goes first.

If we're talking weights between "heavy" bikes such as the Plug and "light" bikes such as the Langster, there are a lot more important things to consider when buying that the 1 kilo or so difference in weight.

. . . . to some people.

my bike put on weight recently.

8kg is light for an OTP, won't find anything much lighter. Some of the Alu framed bikes get close to this
9kg is pretty average.
10kg is heavy which is where the Plug sits I believe.

Whether you run brakes or not can make a difference of getting on for a kilogram.

. . . . to some people.

You're a weight weenie though.. a special breed of mental.

Thanks guys.

I'll be using the bike for a 20mile undulating commute in each direction, with a couple of not insubstantial lumps in it, so with the backpack on, and the fact i wont be able to change gear i was thinking the more weight i can save the better to a certain degree...

2007 54cm Langster, frame, fork, headset, and seatclamp: 2.1kg

The Pergotti Respondium is made from Stainless steel (columbus XCr), and is one of the lightest steel frames around (maybe). 1.7Kg for a 54cm frame. So a 1.8Kg frame is no slouch.

The lightest steel frame I know is 1.1kg, and it's a Barra 1936 cyclotourist frame.

or 2.2kg with fork, botto bracket, crank, headset, braze on. (made from Reynolds H.M. 3/10mm.

fully equipped cyclotourist bike; 7.960kg

unfortuantely I can't find it when I look at the Google of the world, only in a magazine, but will scan article if anyone is interested.

edit - found it;

^ I'm calling bullshit on that 1930s bike. They must've measured a bike built at size 24cm or only counted the main triangle or something. The ALU saddle and post weighs half the entire STEEL frame? I don't think so.

1000g

"I'm going to kick off with my personal highlight of the show: Reynolds' new 953 stainless steel tubing, as built into a frame by Melbourne's Baum Cycles. Like just about every British rider my age (late 30's, thanks for asking) my first decent bike was made from Reynolds 531 steel, so I have a soft spot for the Birmingham, England tube maker.

However, the rush to build lighter and lighter frames has left steel behind in recent years. Aluminium and then carbon fiber have been the materials of choice for riders seeking a very light frame. Reynolds launched its 953 tubing just a couple of weeks ago and if it delivers on its promise it will put steel back in consideration. At the Bicycling Australia show, Baum had on display what the company's Jo Banks believes is one of just three 953 frames in the world at the moment (the other two tubesets went to Boston, USA builder Independent Fabrications). The weight: 1000g.

Baum's Jo Banks told Cyclingnews that this prototype frame was built to the exact same dimensions as "a well-known titanium company's 800g frame." In other words, this is a weight for a smallish 'medium' sloping frame.

By any measure, a 1000g steel frame is a jaw-dropping achievement. What's made it possible is the extremely high strength of this new material, which Reynolds describes as a "maraging stainless steel, specially manufactured for Reynolds by Carpenter SpecialtyAlloys, USA". 'Maraging' is a hardening and strengthening treatment applied to a class of high-nickel steels. After it's been treated, the ultimate tensile strength of 953 is 1750 to 2050MPa, depending on exactly how long it spends in the over and at what temperature. The strongest steels in widespread use before 953 - air-hardening steels such as Reynolds own 853 - had ultimate tensile strengths of 1200-1400 MPa,while good grades of regular chromoly run 900-1000MPa. A stronger material means you can use less of it, of course, and 953 has tube walls as thin as 0.3mm.

Reynolds admits it's not a frame design company - it makes tubes. It's therefore working with companies such as Baum, and Independent Fabrication to fine-tune the tube design of the 953 set. The advantage of the new material, according to Banks, will not be "stiffness or weight but strength. All steel is the same weight and stiffness but this is twice as strong." That will allow builders like Baum to make ultra-light steel frames that are still durable. As 953 is a stainless steel it will also have the advantage of being corrosion-resistant and being able to dispense with the paint.

Banks estimates that a Baum frame in Reynolds 953 will cost about AU$4,000, which is comparable with the company's plain gauge titanium frames - but lighter.

Really thin metal pipe?

Stupid question going round my mind, in motorbike / car terms having superlight wheels on a similar frame weight improves handling by reducing unsprung weight hence cornering and acceleration requries less energy. Is this as noticable on a cycle?
