Berk PROTO-TYPE 3

[Soloist Assassin]

Just a little tip. Sram Force chainrings are 9g less than Stronglight CT2 available in black, and shift better. I really like the look of things though. That fork looks great!

[...]

Thanks, didn't know will see how I'll be happy with those CT2.


I have one question for all those who have Di2 if they could make me a favour. I'm interested how large is the original battery as on this photo?

What would be the smallest box where you could put this battery without any tuning? I can't found any specifications about it and I would be really thankful for any informations

[...]

And here is PROTO-TYPE 3, just finished - unfortunately bad photos because it's photographed at night (and with my mobile phone) in my work room. Will make some better photos soon.

The final weight is 1013g!
...with internal cable routing and integrated saddle/seatpost.


The graphics are painted and very simple - I like it like that. Some of you will like it, some of you not, nothing wrong with that and comments are welcome :thumbup:.

Mention that it's a proto-type frame for some hard test rides and for my own researches :thumbup:














And one more photo from the fork, I forgot to mention the weight, and it is 362g:


With all the parts together it should look really nice, just can't wait to build it,...Sram Red, Lightweight wheels, KCNC brakes,...will keep you updated!

Good God. Awesome work Jure. I can't wait to see more of your work. I saw some of your work first hand and it's very impressive.

[...]

Gumgardner, thanks!

Here is just one photo, just a teaser how it should look:


And as on this photo it's less than 4kg, only 3982g! At the end it should be less than 6kg, mention that this is with an ALU bar and stem, Elite Custom bottle cages etc.,..without any risky components.

Very impressive Jure, frame looks awesome! You'll be ready to take on orders soon

Thanks!

Today I just get the Sram Red rear derailleur:


144g


Now I'm waiting only for the levers..

[...]

Today, when I came home, I saw that I get the levers and of course I immediately started with the building..

I made just some small cosmetic changes on the levers and the rear derailleur and it's ready to ride!! Already rode with it a few hundret meters here in my street and I just can't wait for tomorrow, when I'll make the first training ride with it.


The weight is 5923 g

Of course with pedals, bottle cages, with 10 bars in the tyres etc.,..just like on those photos. I just made them, hopefully they are OK, will post some new photos with some help from a friend of mine later

Good first post.

Really outstanding work, Jure. We all knew you frame was something special and you built up a really nice looking and light bike from it.

If this would be my only bike I would sure change a few components, but all those parts are for my "test frames" and I rather save some $$ for some new projects

Wow. This has just turned out beautiful. Quite the build!

Thanks !
