Hello!

I am new in the world of road bicycle, and i have today a fuji 1.1 sportif.

This is a bike meant for beginners and i wonder if it is possible to change the frame in the future for a more "racing feeling" and lower weight buying a carbon frame?

Sorry for bad english, cheers

Knowing nothing about your requirements, I'd suggest you sell your bike and use the $$$ toward a new one. That's probably your easiest path to a different bike.

The components on that bike, I'd guess, would be out of place on an upgraded frame.

Looking at a couple of reviews I'd say that that's a pretty nice entry level bike. I'm not sure how much weight you'd save or how much "racier" any carbon frame would feel. Why don't you put say, 30,000km on it and then you'll have better idea of what you want in a road bike.

That would cost alot of $$$ as you called it.

I like the bike as it is today but in the future i would like a bike thats lighter. Keeping the existing parts and buy a new frame would be a good option for me

you will need to get a bunch of tools, probably some odds and ends parts, and some knowledge on how to tear down and rebuild a bike. It's not rocket science but its not trivial either. Do it during a period where you won't want to be riding for a while.

It has been my experience that "parts" wear out long before frames do.

Ride the bike enough and you'll start to know what you need to do.

I disagree. More hassle and cost than it is worth.

As the others have said, ride the bicycle for a couple years.

Then, if you want another bicycle ... go buy one. Keep the one you've got for rain days, or to put on the trainer, or to commute with. It never hurts to have 2 bicycles just in case.

From someone who has swapped three frames using the same basic groupset, wheels and cockpit, if the current frame fits ride it until you save up enough money to buy a complete second bike - except if you really like wrenching and you don't mind actually spending more in the long run.
