Just out of curiosity, does anyone know any really light frames that you can use for fixed? I've noticed that surly's and iros are fairly heavy. I really want to know if there are fixed frames that have road geometry that are also light. My Trek 400 conversion is awesome, but it weighs 24 pounds! Oh yeah, please don't let this thread disintegrate into conversations about putting an eccentric hub on a road bike.

my fuji track pro's pretty light.

any aluminum track bike is gonna come out pretty light if you build it up with light components and wheels.

i hear don walker frames are pretty damned light...

There are plenty of aluminum frames out there. both my steel bikes weigh around 18-19 lbs.

yeah, steel isn't that heavy.
my soma weighs in @ 18.5 lbs

Look for frames made out of Reynolds 853 and Colombus Genius, Spirit, or Life. Those seem to be mostly custom made though.

I find that custom Steel frames tend to be on the light side.

My Sannino is about 18 lbs. CroMo frame and fork, 32 spoke wheels.

How light do you really want? Keep in mind its not the best idea to get anything under 1500g or so if you plan to lock it up(or more with steel.) And that pretty much any reasonable frame can be made into a sub-20lbs fg with the right components.

I don't really have an exact number. I was just curious. And....why is it a bad idea to go under 1500g? I'm sure I could make my Trek lighter by switching some components but thought a new build up with all light stuff could be fun. Not that I'm in a financial position to start it soon, but I'd like to start thinking about it now.

aluminum isn't necessarily going to bring you in lighter than steel. for example, the iro jamie roy (56cm) is only 0.1lb lighter than the mark v (56cm). and, as you know, the mark v isn't exactly the lightest frameset on the planet. the angus comes in lighter than either and is steel.

i don't know of a lot in the way of high quality frames with road geometry and track ends. street singlespeed / fixed gear frames are somewhat new to the market (well, discounting old path racers and the like. i imagine that they are going to be heavier than you'd like). i can, however, suggest that you check out the gunnar street dog. it's a pricey piece, but has a reynolds 853 main triangle with true temper ox platinum making up the rest. i don't know the weight offhand, but can be fairly confident that it comes in lighter than any of the budget offerings.

of course, if you're willing to drop ~1000 on a frameset, you might as well go custom, at which point you can get whatever you want.

What's considered light/normal for a fixie? I sorta figured that with all the 15-16# road bikes out there, a fixie would run a bit lighter. But I also realize that bikes that light also use superlight frames, etc that aren't generally put into fixie-dom.

My Fetish weighs exactly 17 lbs built up.

the steel Jamis Sputnik is ~16.5# and costs $800 for a complete bike, replete with carbon fibre components

a Bianchi Pista concept can easily be built to 15#, and the frameset is $550

i started a thread a while back asking how much people's rides weighed. most were in the 18-20# range.

perhaps you should concern yourself more with proper fit and ride quality. if you want to save weight, concentrate on the wheels.

1500g isn;t an absolute rule it's just below there you start getting into really thin walled tubing. Tubing that was not designed to be bumped from the side. Riding such a bike around town and leaving it outside locked to things is not a good idea.

I have 2 bianchi concepts. one is 15.8 lbs and the other is 16.2 the diff is carbon front wheel vs. spokes. oh and a brooks.

yeah, i can't believe i actually recommended someone get an aluminum bike. as i said, mine's light as hell but the many benefits of steel outweigh (pun intended) those of aluminum.

and +1 to saving weight on your wheels more than the frame.

my Fuji track fully built up is around 18-19 pounds.

just put a massive dent in my downtube last night.

About a year ago I corresponded with Mercian Bicycles about a custom frame, with weight as well as fit in mind.

They told me that materials did not determine weight so much as they determined ride quality.
They told me to pick the type of tubing based on how it would change the ride and performance, and not on how much it would weigh, because, in the end, most frames, regardless of material, weigh about the same.

Further, they said if I didn't know in what ways the various types and mixes of tubing effected ride and performance, to tell them what kind of riding I do and they would choose the tubing for me.
They suggested that for me, Reynolds 853 tubing would not save that much weight and Reynolds 725 or Reynolds 631 (or a mix of the two) would weigh about the same and give me a better ride, for the kind of riding I do.

A custom Mercian Super Vigorelli frameset delivered to my front door would run about $1100 in US dollars.

um, you could just leave your messenger bag at home and that'd bring you down 20-30lbs. If I were you that's where I'd start

i just swapped my concept for a carbon gan well and my bike gained a pound. 15.6 to 16.4

18 pounds for an XL Bowery with mavic ellipses, and I could go to 17 or even 16.5 with some lighter components.

19 for an old steel schwinn prelude built up with stock stuff and a cheapo nyc rear wheel
paid a total of $150 and I love the thing

Red Menace's Kiyo all steel and LIGHT! I got the bike down to 14 lbs before giving him back the frame .

S/F,
CEYA!
