How Heavy is Your Bike?
Was wondering what the ultimate in light weight (probably
road bike) is these days. Are they under 18 pounds or so now, with the carbon materials? How light is the ultimate light weight bike? (How much money??) And how heavy is your bike? I have four with the lightest one a mostly stock Trek 2000 at perhaps 22 pounds as set up. Mike J probably knows their stock weight. But weight isn't much of a factor for me, and my touring bike is probably a 35 pounder as set up for daily commuting (can be an 80 pounder for touring). I have a new Raleigh MTB (Mojave 5.0) that despite its AL frame, has got to weigh in around 40 pounds with "my stuff" on it. Not certain why it is so heavy; cheap front suspension fork? Chinese made tubing with 1/4 inch thick walls; 2.2" tires??!!! I understand as far as MTBs go, it's not considered especially heavy in stock form (just seems so to a roadie I guess). Whatever, it's my rainy day commuter, MTB and winter standard commuter and the heavy-weight of my bike stable as I have it set up. So...stock versus service weight for me: Trek 2000 about 21 pounds (??) probably 25 lbs Trek 520 26 pounds 35-80 lbs Raleigh MTB about 30 lbs (??) about 40 lbs Trek 7000 MTB about 25 lbs (??) about 30 lbs SMH |

No freaking way. Saw a custom Serotta with D-A tubeless wheelset on yesterday's ride and it weighed over 15 pounds. (Maybe even over 16.) Absolutely gorgeous bike, easily $10K, but nowhere near 14.2 pounds. Bill "boat anchor Madone SL (doubt it's under 17)" S. |

[snip] Dear Stephen, An email pointed out your thread and asked me if I had posted something about a light bicycle: http://groups.google.com/group/rec.b...d9776b77581c96 That's a rideable steel bicycle from 1895 with 28-inch wheels, weighing eight pounds, fourteen ounces (about 4,034 grams). Solid rubber tires and the huge front wheel made it hard for highwheelers to achieve such anorexia, but 52-inch production models managed to sneak under 12 pounds: http://i30.tinypic.com/w1v7ft.jpg --p. 25 "Bicycles & Tricycles of the Year: 1889," Harry Hewitt Griffin Cheers, Carl Fogel |

The description of that bike says it was made from 0.016" thick steel tubing, presumably straight gauge (I'm not even sure butted tubing existed yet then). That is 0.4mm wall thickness, To my knowledge, the lightest gauge tubeset that was regularly available from in the classic-steel-frame cro-moly era (1970s until now) was 0.7/0.4mm butted, and this was regarded as a very specialized set for lightweight riders on occasional-use competition frames. 0.8/0.5mm or 0.9/0.6mm would be much more common. Even now, True Temper OX Platinum, which is one of the highest strength air hardening steels that is used for bicycles, comes in 0.7/0.4mm tubing at a minimum: http://www.henryjames.com/butt.html Steel tube in 1895 would have been lower strength and they probably didn't know as much about minimizing heat affected zones at the joints. In other words, I doubt there is anything magic about the weight of such a frame. I just expect it would not have lasted very long in use, especially on roads of 1895.

Torelli says their tubeset uses Columbus Nivacrom, which has a tensile strength around 140 ksi. That is somewhat higher than plain 4130 cromoly, Reynolds 531, or Columbus SL, all of which are around 100 to (maybe) 120 ksi. These are the steels I think of as what people built "classic" steel frame out of in the 70s and early-mid 80s. Then fancier alloys and air hardening steels came along, which allowed somewhat thinner tubing and oversized steel tubes without much of a weight penalty. For ex, Reynolds 853, various True Temper and Columbus tubes. In the 531 and SL era, there were lightweight tubesets make out of the same steels, but they weren't very common. For example in this Columbus catalog: http://equusbicycle.com/bike/columbu...cat/index.html there's SL (0.6/0.9mm) and SP (0.7/1.0mm) tubesets for general use, but you could also get a Record tubeset at 0.5mm and a KL tubeset at 0.5/0.7mm. Columbus described Record and KL as for record attempts on the track and for time trials on good roads, respectively. I assume that they meant "Don't expect this to last forever, especially if you're a Masters Fattie that hits potholes." There are still about two jillion SL and SP-framed bikes out there, but not so many KL frames; of course there probably weren't very many made in the first place. One can only imagine the fate of a bike made from 0.4mm tubing with 1895-era steel. Ben I just want to know if the 1895 manufacturer weighed the bike without pedals. |

I suspect that the practice of providing bikes without pedals is a modern custom. Here's an 1897 example of pedal choice: http://www.blackbirdsf.org/white/ima...atalogue27.jpg You get one kind of pedal with bicycle models A & B, the other kind on bicycle models C & D. Similarly, the 1898 Victor comes with pedals: http://www.amoser.ch/christian/quell...ges/page05.jpg And the 1917 Hawthorne Regal Racer comes with "specially selected Star ball bearing light weight racing pedals, very light, weighing 6 & 1/4 ounces each" (about 176 grams): http://www.nostalgic.net/pictures/1211.htm I've browsed a fair number of old bicycling catalogues, and off-hand I can't remember anything like the no-pedal look of our modern bicycle ads. If the 1895 bike had been exhibited without pedals, I'd expect that to have caused comment from the people who lifted it. (Imagine a weight for a modern bike that didn't include any seat.) Clipless pedals were invented in April, 1895, and none of their variants caught on, so the odds are against them because the drawing appeared on the cover of the Scientific American, Feb. 9th, 1895. Below are the details from page 86. Note the comment that racing bikes were regularly down to 15 pounds. I don't know what kind of steel forgings were used on all the joints. "The curiosities of the show [the 1st National Bicycle Show at Madison Square Garden] included several light wheels [the term then meant entire bicycles], and we illustrate a real wonder in this line, an 8 pound 14 ounce Tribune bicycle, shown by the Black Manufacturing Company, of Erie, Pa. It is full size throughout, having 28 inch wheels and a 43 1/2 [misquoted as 3/4 in "Riding High"] inch wheel base. It is only on taking it in the hand that its lightness can be realized. It has 13 ounce [~370 gram] M. & W. tires; the tubing is No. 26 gauge (0.016 inch thick) and steel forgings are used for all frame joints. The full number of spokes are used for the wheels, 28 for front and 32 for rear wheel. It has been thoroughly tested by an average weight rider and is doubtless the lightest full sized wheel ever made, being a veritable tour de force. Regular racing wheels are made as light as 15 pounds in weight." The ~370 gram tires were probably like our modern tubulars, with the weight including the inner tube. Cheers, Carl Fogel |
