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.

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.

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

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

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?

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

Excellent job on the build!
