Est. Top Road Bike weight in 3 years - 15 lbs ?(10 posts)

Est. Top Road Bike weight in 3 years - 15 lbs ?Maartin

Since most top bikes are in at about 17.5 to 18 lbs. do people think we will see a Dura-Race (for example) equipped bike at 15 lbs. in three years ? They get lighter every year so why not ?
You can get them nowstr8dum1

As people are more and more willing to ride disposable frames, the big co's will keep on makin em. Its great business for them. Build a frame thats stupid thin and fatigues in a couple years and the rider will have to buy another one. DA components cant lose much more weight. The only place to really save weight is in the frames.

I dont think pro will be racing on bike less than 15 -16 pounds (even if there was no UCI limit). to get bikes that light you have to start spec'ing iffy equip. Gotta finish to win.

Do you mean the average high end bike at a particular price point, or the lightest bike out there, no holds barred?

There have been several factory bikes (one of those being a Schwinn) weighing in around 13.9lbs for the last couple of years.

Think about it from a historical perspective. In 1990 there were DA steel and alum bikes that were as light as 19-20 lbs. In 2002, a pretty light Ti, Al or Carbon DA bike will be 16-18lbs. Most of the weight savings is from lighter frames, all carbon forks, threadless headsets, and custom wheels. Components haven't seen that much of a drop in weight. In fact, the STI shifter may have added a little weight to the component package.

I'm more interested in my estimated weight in three years!!!

In going from 18 to 15 pounds does that mean the bike will also be 17% more enjoyable to ride? Bikes have gotten lighter over that past 2 decades through improvements in design, materials and production techniques. However over the past couple years it seems like additional improvements have come at the expense of durability. I struggling with how bikes can get substantially lighter without putting a weight limit and use limitation on them. I'm not against light bikes, but I'd rather not lose sleep worrying when my frame is going to snap. Besides I can use my 21lb steel bike as an excuse for being slow whenever it is convenient
Mine will still weigh whatever it weighs nowSilverback

Because it's perfect for me and I'm not going to fool with it.
How much did bikes weigh 3 years ago?filtersweep

About the same as today...? Huh...?

You need to remember that a "top end" bike is usually designed for its ride - the weight is an issue, but it isn't the ONLY issue. Example: Ti bikes are quite expensive, and Al bikes at half its price can be easily lighter. I doubt any 15lb bike can match a well designed 17-19 lb bike for comfort and durability.

My fear is that there will be all sorts of "integrated" propritary parts to save weight- headsets, and BBs... probably even more stem/bar combos and some of the modularity and adjustability of bike design will disappear if WEIGHT alone becomes the focal point.. but I doubt it ever will fully come to that point.
Whatever happened to lifetime frame warranties?Chainstay

These are going away as fast as all that unnecessary excess weight. The industry is on a fad diet and now some Colnagos only come with a one year warranty. We have new materials in various bonded combinations, thinner tube walls that beer-can and seamed 6/4 Ti tubing. Manufacturers are rushing unproven designs in response to market pressures to innovate or die. Also Carbon Composite bikes usually cannot be repaired at all and Aluminum repairs can be pretty questionable so enjoy your light bike but don't crash it.
Lifetime warranties are offten just a gimmickColnagoFE

If you read the fine print the warranty often is void if you race or crash and after reasonable wear and tear from "normal" riding. The only time it's covered is if there is a manufacturers defect and that usually appears pretty quickly--not 10 years after you have the bike.
Unless your frame failsChainstay

I had a Specialized Allez Epic replaced after 6 years and my brother had the same style frame 11 years and it was replaced. That was no gimmick. Specialized used to have a great warranty. Now it's only one year.

The above failures were at the bond between the cast Al BB and the Carbon Fibre chainstay. This is a fatigue type failure. The kind of failure that you might expect from a frame that is designed too close to the limit or uses an unproven construction technology.

A friend of mine just had an Aluminum frame(a Guru with Carbon wishbone seatstays), fail at the rear dropout on the chainstay after 18 months of hard use (He is a 210 pound sprinter). All the manufacturer offered was to repair the frame.
