Weights of light weight bikes over history(8 posts)

Weights of light weight bikes over historySLM
Apr 13, 2001 7:30 AM
Just out of curiosity, would anyone know how the weights of road bikes (racing) have changed over the decades?
Example: would a lightweight racing bike of 2000/2001, say in the 75th percentile (100 percentile being lightest) weigh about what? What about 1990, 80, 70, 60,50 etc? Anyone have any ideas, or know where to find some data?

no idea...but a friend of mine was talking to me about his superlieght bike that he used when he was younger (probably in the mid-early 80's) he stated a weight of around 25 or 26 lbs (actually, he knew the weight to the tenth of a pound)...
he was sooo proud of that...i almost felt bad letting him pick up my litespeed :)
25 lbs was NEVER superlightKerry Irons

except in the eyes of the owner. For reference, from the mid 60s to about 1990, standard road racing bikes (steel frame with 0.9/0.6/0/9 mm double butted frame tubes) with Campy top of the line components and 350 gm tubular rims weighed in at right around 22 lbs. I bought one in 1969, and that's what it weighed. So did the one I bought in 1972, and so did the one I bought in 1988. However, around 1990, there came the end of the cold war and a huge surge in the availability of aerospace materials for non-military uses. All of a sudden, Ti in frames, bolts, axles, stems, seat posts, high end aluminum alloys, advanced CF techniques, etc. came flooding into the bike market. Frame makers and component suppliers got the weight shaving bug, and now a "standard" high end racer comes in at around 16.5-17.0 lbs without much of a stretch. As another aside, racing bikes of the 40s and 50s were around 24-25 lbs, when aluminum alloys weren't as strong, roads were rougher, and tires were heavier. The light bikes of the early 1900s were track bikes, and so still would weigh 4-5 lbs more than today's equivalent.

one of the bike mags(i belive bicycling) did a comparison on weight of a set of masi's both of which where alsmost the same weight the older one was slightly lighter. They used the bike from breaking away as a comparison, and used a modern that was similarly equiped. This was a couple years ago when sti first came out and accounted for a large amount of weight.

I remember that article (I might even have that mag at home). I was going to comment about maybe a slight rise in weight around 1991 when STI's first came around. But I would find it very interesting about the trend of the weight over time. Was it a gradual decline, or were there periods in time when greater decreases were seen due to technology etc?

I've also got a set of uniglide hubs and casstte from the shimano 600 series(2 sets actually) and both the rear hub and cassette weight less than current ultegra. The rear hub it's self is lighter than a current dura ace rear based on the specs that shimano gives so there has been deffinate changes both ways. On the plus side having 9 gears is nicer than 6 and the older freehub bodies weren't as water resistant. TTFN

i was looking through a real old Sears and Roebucks catalog at the local library awhile back and was amazed by the advertised weights of some of the bikes they were selling. i can't recall the exact weights, but i remember they were well under 20lbs and the catalog was published very early in the 1900's. Bare in mind that these bikes were fixed gear racing bikes with one gear and not much else, but still.
Let's go back to about 1890-1900 ...Humma Hah

... I've got a book that covers this period, I believe its _The American Bicycle_, which shows several examples of roadbikes of that era which weighed about 18 lbs. These would be steel-framed "safety" bikes looking quite similar to 80% of modern roadbikes, typically fixed gear with composite (wooden) rims and pneumatic tires. Ridden on roads they were essentially cyclocrossers (there was little pavement at the time). With little modification, the same bike would be used at a velodrome.
