Lightweight Bicycles
Test data indicates that the combined weight of the cyclist and the bicycle greatly impacts the speed during climbs (http://www.analyticcycling.com/ForcesLessWeight_Page.html)
I use the following sources for information on lightweight bicycles, parts and components:

I would welcome comments and additional information regarding lightweight bicycles and lightweight bicycle parts.
If anyone is interested in getting details on the world record bike please leave me a comment.

BTP from Germany makes a line of light hubs, seatpost clamps, bottle cages and wheels. THM, another firm from Germany makes super light forks and cranks. Easton makes a very light fork and handle bar. Reynolds composites makes the lightest bicycle rims and wheels. Zero Gravity makes the lightest brakes. M2Racer, which is no longer in business, made the lightest saddle, seatpost, pedals, quick release skewers, seatpost clamps and bottle cages.
Is that thing rideable?
Yes, it is a road worthy bike. The super light wheels at around 800 grams for the pair and the tires at 95 grams each make downhills a bit tentative. So, I go downhill pretty slow. But, climbing is a dream!!
FYI -- in LIGHTEN UP! "three days to investigate the ultralight bicycle" is set for next weekend in Philadelphia, april 13-14-15. It's FREE. More info at www.trophybikes.comthanksmcget
I would imagine that no matter how ridable you think it is that shifting hard on a carbon chainring will shred it. Certainly the few who make them say so. Also, ridability? I am a gram counter myself and the lighter things get, the harder they take abuse. How many real miles are on that thing?
Nice bike. Would have my concerns about the carbon chainring also but it looks good.

Thanks for your comments. The carbon chainrings aren't for everyday riding and have a relatively short life. Also, shifting under load really reduces the life of the chainrings.
Aslo their price is huge - that's the most disadvantage as for me.
Interested in the details on the super light weight bike - especially companies where the parts are available. Thanks.
these bikes are light, the claim that they are the world's lightest bikes is a tad optimistic though. for the lightest roadbike check http://www.lightbike.de/Lightbike_2_9kg/lightbike_
The German bike is impressive. Thank you for sharing with me.
Great weenie work!!
Dont want to know the price tag;)
When it comes to weight, UCI in competition has a weight limit of 15lbs. For a rider of say a 165lbs, total weight of 180lbs, as opposed to 185lbs (20lb bike) the main disadvantage will be in a sprint for the finish line. In theory we could debate that this is a 5/180 = 2,8% disadvantage, but there are many other factors coming into play, such as flexing of the frame and the weight of the wheels, which are rotating mass.
The stronger riders prefer stiffer frames for climbing and sprinting. During time trials, weight is not that important.
Personally I prefer something in the 20lb range, just gives me more confidence in those 40mph bumpy corners when going down the switch backs.
Light wheels, which are durable, are much more important than the frame and components.
I want to buy this light weight bike, How and where I can buy it .
How much are you willing to pay?

Which brands today make the lightest/best components? I'd imagine BTP for hubs?
