I dont really care cosmetic.. I don't know what mods you are thinking of that look ugly..
I would like a more snappy, fast accelerating bike.. The special "light" bike feel :) ( FIY, i get that feeling at anything under 8kgs..)

The first im changing is the cranks, they are abit worn.
The rear wheel have big grooves on the braking surface.
The stem needs to be abit shorter.

So that's the stuff i want to change first.

Current weight as pictured is 8660grams
The cranks weigh 820 grams withouth bearing, with chanrings.. What is reasonable priced and weigh less?

The steerer tube is fully carbon, and it originally has this sleeve for reinforcement. Do you guys think its safe to use this normal topcap?

Sanded down the fork and removed the PREMIUM logo and re-coated it. Looks nice!

Tried a friends Scott Foil today.. I'm missing soo much out with having a too large bike.. I might buy a Chinarello or something.

Nice bike, I like what you did with the fork. I read your 'what frame should I get' thread in the road section. You said you're new to road riding, so maybe you don't have the 'feel' for the road position yet. You're supposed to be 'stretched out' to a certain extent on a road bike, and at 6ft, a 58cm wouldn't be out of the question for you (though this depends on other factors too) Lance is 5' 10" and rides a 58... Another way you could shorten the reach is with some compact handlebars, I like Deda bars.

Not OK to use the star nut in a carbon steerer tube. I see it in your picture - did you use it?

No, because you have to carry a spare tire

I was thinking stans fluid, a pump and some superglue.
Anyways, as you now, rotating weight is the important stuff.. So if i have a little tools box it doesn't matter as much.
My normal trip (50km) is anyways around a water and a mountain. The highway goes inbetween the mountain and the water. Call a friend, and 10 minutes later i have my tyre or get picked up. On longer trips, my tools bag will be carried with me.

Thanks! yeah that's probably true.
I'm used to a all mountain bike with pretty tall front end. So it felt really strange sitting on a road bike.. Not relaly WW worthy bike but it's loads of fun.

I have been experimenting some with positioning on the road bike, and now i have it the way i want it atleast and i'm happy with how the bike rides. My pedaling feels more powerfull, and i can ride faster for longer.
I might change my frame anyways.
I have a veteran car for sale, i have a good bid on it now.. If i sell it for that bid, i will have extra money for some fun. Possibly a new road bike!

There are some threads in the steerertube originally. I only keep my starnut together with my topcap and topcap bolt. So i dont lose any of them :D
