this i have no real idea on, but one thing i know is that the Trek Madone frame is one of the lightest available.
Making this frame into a fixie would be :-

a] possible ?
b] given a] is a yes, awesome ? or
c] given a] is a yes, plain daft and not cool at all ?


just a gander at a fleeting thought. What you think boios' ?

i reckon it's a waste of a perfectly good road bike.

Ccccccccccccccccccccccccccccccccccccccc

Possible but stupid.

you could buy the frame separately i'm sure.
for those with weight saving addiction this is the killer conquest, the holy grail, given the killer rabbit is not about or otherwise you have the holy grenade at hand :D

i would prefer to just buy a normal track frame.

Did someone say fixie?

Bollocks. The Madone isn't even that light - it's just a good all-rounder.

THIS is light..

3.26kg / 7.2lb

thats a mad-one hippy, *cough*

Ghisallo for me:

S M ML L XL
Frame Weight (grams/lbs.) 765
1.69 770
1.70 840
1.85 890
1.96 915 lbs.
2.02 kg

The lightest stock road frame you can buy is the Scott Addict @ 790g as opposed the 1070g for a Madone. Putting aside the fact that I shaved more than 280g off my all-up weight when I went to the toilet this morning, you need to ask what the objective of building this up fixed would be. If you want to go fast on the flat, being stiff and aero is at least as important (TT bikes aren't that light), if you are doing hill climbs then you can lose the weight getting rid of brakes, and chopping bits off you handle bars. If you want to do climbing (as in alpine stuff) then having a light bike is great, but fixing it screws you up on descents.

As does lightness - heavy = fast going downhill...

This is true of course, but I still manage to coast downhill faster than a lot of much heavier riders. So is this the aero advantage of being a fairly compact individual (with a good 'tuck') outweighing, so to speak, the lack of mass...?

Compact individual.. I've gotta use that one!

By far the heaviest part of your bike is you. In my case my bike accounts for about 14% of the total weight of me and it. For my flatmate who weighs 20kg more than me it's only 11% of the total weight. that's assuming my bike weighs 10kg which I think is pretty wrong but it's a fair guestimate for the case of my argument.

15pounds is not that light

Not for a baby it isn't but I'd say it is pretty light for a bike, around the TDF lower limit...

ridiculous idea.

I have always fancied one of these as a fixie . . .

Just buy the felt track frame?
And have a track bike?

3.26kg / 7.2lb[/QUOTE]


Aidan has that saddle.

felt are doing this as a pursuit bike next year according to the rep

bloody hell look at that thing...

They have one of em in SBR/Bonthrone bikes in fulham . . . i came very close to signing my life away on the never never for it

Yuk. Most TT bikes are feckin' hideous these days.
Cervelo and TIME for me (if someone gives me the cash).

It has all got a bit sci-fi, but the engineering on it is beautifull.

Still think Lotus had it licked:



though this is the frame i would love to use for my ultimate techno fix:

thats correct.

lance had a fixed madone, they swithced out the dropouts for track ends- looks ok if that5 kind of thing is what you like

Loving the new log-in schri...

the felt was proven as the most aerodynamic tt bike last year and it being ridden by team slipstream this year

heres the prototype

http://www.cyclingnews.com/tech.php?...s/lance_tunnel

Proven by who and in what conditions? It's still ugly.
Aero also doesn't equal fast if the frame handles like wet spaghetti.

Lance never went for the hour in the end though.
That guy needs to Harden The Fuck Up.

ive rode one they feel brilliant great handling and there was a group test of all the major brands last year in the wind tunnel and the felt came out on top i think it was cycling weekly think or pro cycling

These Trek Madones are beautifully tuned for geared road racing. I have a 5.0. I have ridden a 5.2. I can't understand how they can keep making them better and lighter. It doesn't make sense to convert to fixie and to think you can do that and do justice to the frame is daft.

great dredge, would love a stupidly ott frame to ride the spice route on....

madones are relatively expensive, why not just get a fixie frame instead? also they dont look quite right as fixed i think

Fixie!

fixie fixie fixie!

there i said it. i feel dirty now.

id only do this if i had access to a cheap second hand frame or end of line model. theres no point dishing out for an expensive road frame and convert it when you could just get an actual track frame. with that said there is some merit to using a road frame for a bike that never sees a velodrome.

Already exists

I've ridden one; they feel brilliant, great handling. There was a group test of all the major brands last year in the wind tunnel, and the Felt came out on top. I think it was Cycling Weekly or Pro Cycling.

Fixie...fixie!?

FIXIE !?!!





Good God, Sir...

sounds like a job for the

FIXIE PIXIE

it has to be said, this looks wicked. if they hadn't got the price point so badly wrong, and instead sold it for £1000, they'd make an absolute killing.

Whats the damage on those things?

street price : £2800
