this would make the fastest fixie conversion
 

i know theres a sticky for hot track bike/fixie deals on ebay, but this deserves its own thread!! http://cgi.ebay.com/ws/eBayISAPI.dll...130183471&rd=1
10 lb miyata, complete! :eek: i cant believe no one has bid yet...

If that weighs 10lbs my 50yr old English 3-spd weights 15lbs! :rolleyes:

no, this doesn't deserve its own thread.

:p

no, seriously, it would be a nice converstion, but that bike does not weigh 10 lbs.

Now... is that 10 lbs. with or without the blue cable lock wrapped around the seat? :)

This bike is 10 lbs.

Yeah, that dude needs to take the proceeds from the sales and get a new bathroom scale. UCI limits competition to bicycles weighing 15lb or more. That thing ain't under UCI weight. I'd guess that at best it's around 21lbs which ain't a bad number.

If that weighs ten pounds, so do I. It's a cromo frame, forgodssakes. Winter beater.

i think he weighed it on a see-saw

Maybe 10 kgs?

Can't you see! To the untrained eye it is a cromoly frame, but if you look closely you will see that it is a CHROME MOLIBDENUM frame. Molibdenum is an ore that is found only on the top of the highest peaks in the Alps. It is super light and strong on its own but when combined with pure chrome it makes an alloy that is stronger and lighter than any other. Jeez, I can't believe you guys missed that one. :D

I think the UCI limit is 14.98 lbs.

I believe officially it's 6.8kg which is 14.99lb. I'm sure it's not coincidental that it's so close to 15. But I suppose the weight weenies will be looking to shave that last 0.01lb off, so I should be more precise.

i would say it's probably used as a margin for error. Like if your super-precise scale was 0.01 a pound off or something. You know how close people like to cut it.

i was reading some stuff the other day regarding UCI weight restrictions and aparantly, if you bike is too light, you can just throw another water bottle cage on it, or heavier wheels. Or drop a few marbles in the seat tube.

lying about bike weight is rampant across the internet. seems to me that people shave off 2-3 pounds when trying to sell a bike. in this case, the guy shaved off probably 12-15 lbs.

A super precise scale isn't off by 0.01lb. That's a pretty gross margin of error.

And yeah, UCI doesn't care where the weight comes from. Most people will choose to have that "extra" weight be structural (ie, in the frame), but it's not always the case. It's up to you to find the appropriate balance between frame, components, and accessories weight.

Lance's TdF bikes have been light enough that they've intentionally chosen heavier components to bring the weight back up. Of course we also know that they've suffered frame failure (I don't remember if the failed frame was "underweight" or not).

are you talking about that broken chainstay, or something else?

I once saw a picture of a Cannondale 6-13 that had weights taped to the top-tube to make weight.

Because I'm lazy and don't want to bother with the 'Search' function...

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.

Woah, yeah.. I'm a idiot. good call.

timmhaan, yeah I'm talking about the chainstay.

yeah that "legalize my cannondale" is absolutely crazy.

chainstay only failed when it got run over by someone else.
maybe if it was steel it would have only bent & then Lance
wouldn't have been able to keep riding & would've had to
wait for a change & then he might've lost & then all of
pro cycling would've fallen apart....and no one would care.

This guy appears to have tried but it came out to 16 1lbs. You probably could lose a little weight by taking off all of that brake crap and the computer. This thing has enough carbon to make me want to barf:

Yeah, there was some impact trauma that damage the frame, but the point is that making the frame lighter did make it more fragile. That was an unplanned-for event, to be sure, but it's also quite possible that if it had a few more plies of CF it would have been ok.

Kind of like internet dating...

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.

Lay off the chimichangas and invest in a good dictionary

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.

i think they can take the force but not the heat from downhill braking. they dont have
that heat dispatching foam in the rim. the standard set is much cheaper. and still
lighter than anything else. I heard of people commuting in 2 tons air conditioned
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:
