Has anybody undertaken a fantasy build of the lightest possible fixed gear? I imagine it wouldn't be too difficult to get it down to the 8 lb. range... maybe a pair of Lightweight Alpe d'Huez wheels built with a Suzue Promax carbon rear, Zipp carbon cranks, some compact geometry 6/4 Ti or carbon track frame, AX Lightness one piece carbon seatpost/saddle... might be a fun little undertaking.

yeah that would be cool. there is a Lightweight track wheel set available so no need
for that heavy promax ;)
have you seen the specs on the website? there is no rider weight limit for those wheels. its even used for cyclocross and still only 480g for the front.
they would be perfect for daily use because they are so durable but I am not sure
how long a carbon braking surface lasts.

That's why I spec'd the Alpe D'Huez set: 'Uphill Only' because the braking surface was lightened to such an extent that it wouldn't withstand downhill braking forces. So just do away with the brakes! :)

$5000 Lightweight wheels on a daily use commuter... Oh baby. And I think that with carbon rims it's not an issue of the braking surface wearing down so much as the cork pads rapidly deteriorating.

steel boxes.

Hmmm... 2 ton air conditioned steel boxes costing 4-10 times as much as a set of Lightweight's... might almost justify buying a pair :rolleyes:

While not 10 pounds, that thing is deffinitely worth $60. The Five-Twelve is really light for an 80's steel road bike. The frame is triple butted cro-mo and the lugs are nice. I have a slightly newer one with the triathalon decals that has frighteningly steep geometry (tighter than my Soma Rush) and handles beautifully. If you used light track parts I bet that thing would convert to between 15-18lbs.

Well I guess the way to go would have been to use Campy low flange which weigh in at about 488 grams a pair, whereas the Phils weigh about 625g a pair. He could have saved a whopping 137 grams! That works out to almost 1/3 of a pound!(Boy does that seem silly. Why do people really care about this crap?)

While looking into this I noticed that the carbon Suzue hub is not as light as you might think. They weigh 574 grams a pair.

The first posting in this thread says the bike weighs 10lbs. He must have put wrong weight on it. The Ebay ad says 20lbs so the seller may be correct. I think the bike is a nice bike to convert to fixed.

remember your significant figures, lad! 6.8 kg is 15.0 lbs. if the official weight limit is reported as 6.80 kg, then 14.99 lb is okay.

you are correct that a good analytical balance can weight a 15 lb object to the nearest 0.01 lb, an accuracy of +- 0.067%. it might be tricky to get a bicycle on one of them, however.
