Ultra light bike

[Alfonso]

Hi.
I present my new project.
My challenge is to reach 3 kg with materials and components known by many of you, to say that it is not a bike that I usually use, nothing more than for a ride since I have other bikes with components that do not suffer so much wear and tear on many of these Components and are safer for everyday use.
I hope you like it and I'll give you tips to keep lightening up, criticism and suggestions.
A greeting to all.

To say that according to this in the photos, it is in a weight of 3,200 gr.

great first post! More info on build list, what you did to get it this weight etc would be useful

[Fiery]

Lighter than Donald's bike without resorting to downtube shifters? That's quite something... More details would definitely be appreciated.

Yoikes! Nice one.

Yes, a complete build list down to the bolts might assist us to provide better feedback.
We can only speculate with some of those photos, for example:
Are those standard hood covers? Or could you remove that weight and go with a lighter cover/wrap for the ergos?
First pic shows some apparent slack in the chain, could you remove a full link?

Looks great though. Finding another 200 grams will be a feat.

Impressive. 3.2kg on an FM-066SL. A build list with weights please.

Nice
Would like to see a build list as well.
Which fork is that?

Very interested as well. I am looking at getting an open mold frame for a sub 5kg build and any ideas always help.

Interesting parts on that list. The wheelset sounds nice.

The bike looks great, and obviously that weight is very impressive!! What plans have you got to save a few grams next?

[Kayrehn]

The weight of the frame and fork is pretty incredible. A check on HF website says the frame weight range is 780-920g; did they make it lighter previously?

[Juanmoretime]

Has Tufo tires improved? While light they were always the worst at rolling resistance and road noise.

Excellent job on the build!
