I think you make a good decision,and put education on first place and you are looking ahead on your feature,thats good. I had the same problem,i was thinking,that i will find some nice job,and i need no education( one of the title of Pink Floyd song os a lie:)),but if you want have a better $$ job you have to be more educated,i think you know what i mean. Its a little OT but very usefull and its a true.

Just one photo - seatstays:



Each only 28g, and I still have to cut it a bit..

And here are the rest of the parts on scale, a bit better photos (click on them for ful size). More or less I only made some small cosmetic changes (a few black bolts, removed the red painting etc.,..) and now it is like I really want to have it

Ritchey Superlogic 42cm (c-c): 190g


Ritchey WCS 130mm/- 17*: 137g


Sram Red rear derailleur: 144g


Seatpost clamp: 13g


Chain-catcher: 9g


Sram Red front derailleur with 34.9mm clamp: 84g


Look Keo Carbon pedals: 229g


Sram Red levers: 294g


Sram Red crankset BB30, 53/39, 172.5: 624g


Sram Red brakes + Lightweight brake pads: 283g


BB30 Press-fit bottom bracket: 88g


Wilier bar tape: 93g


FSA tapered headset 1 1/8 - 1 1/4: 68g



+ Sram Red chain, Enve fork, Berk frame and seatpost combo, Elite Pase carbon bottle cages, cabels (Jagwire, or maybe even Nokon?..)..

The build will be around 6kg, will see..it will be light, but the weight is not on the first place, first I want to have a really stiff and reliable build that will also look nice..

I also just laminated the dropouts...wanted to make some more work, but I have to get some new material if I want to continue with the work,..and I already prepared all the carbon pieces . And I have one more problem, it's very cold here (-14*C right now) and the water instalation for my workshop has frozen

Jure:

Like so many regulars on the forum, I've become a fan of your posts and love learning how CF frames are constructed from your firsthand experience.

I was also very interested in your most recent post with your LW wheelsets' specs/weights. With so many different rim/hub/spoke combos being used by the regulars, often w/ only estimates of weights based on manufacturers' data which can be suspect at times, I really appreciate seeing the real weights and build specs of actual wheelsets to learn what people are riding and what's possible. I started a thread titled Just Wheels (http://weightweenies.starbike.com/forum/viewtopic.php?f=3&t=99279) in the hope that members would contribute their data so we could gradually assemble a catalog of actual wheelsets. Not much response yet. Would you post your LWs wheels on it to help?

Cheers,

John

Hello Jure,
nice work and wheels. But I can see, that both wheel sets are nearly the same weight. So I would like to ask You, if You can feel any difference between Ventoux nad Standard. Can You feel those 25 gramms when climbing? I know that the weight is distributed a little different on Ventoux and on Standard. Do Ventoux climb noticably better?

Martin

@Fourthbook
Glad to hear that, thanks. I already posted the weights also there, didn't saw the topic before that and I think that it's a great idea!


@Martin1977
Unfortunately I wasn't able yet to test them. Right now we have snow and it's very cold (-10* or even less)...as soon as I'll ride them I'll write a ride report!

The weight difference is really quite small, also because on the Standard there is a bit lighter cassette (I think that the Dura-Ace is 180g and the Sram Red 167g). It's more about the handling, not about the weight. And as long as I'm a lot on my bike I prefer to ride with a lower profile, and with the deep profile only 1-2 per week, depends on where I'm riding..I'm a lot in our mountains. But as I mentioned, the weather conditions here are at this moment quite bad and probably I'll manage to finish my frame before the weather will get good enough for cycling (hope that even in this month)


Here just some more parts on scale - just get my favourite bottle cages today

Elite Pase carbon: 59g /pair


Sram Red chain: 251g


Enve 1 1/8 - 1 1/4 fork: 357g

It's still uncut (350mm) and I'll have to cut 135mm (to 215mm ) so it will be even lighter then

Hi, just a small update, this time not really good news. I just worked on the tubes for the internal routing, and saw that there are some imperfections around the cable-stop area on downtube and also toptube. There are some air voids around the grooves and I really don't wan't to use something that isn't perfect, so I'll make a new downtube and toptube - this time without the "integrated" cable-stops. I'll make them after I laminate only the tube.

I made some calculations and probably won't use the ALU small tubes for the internal routing. Why? I can instal the cables also without those tubes, of course it takes some more time, but it's true that you don't change cables every day.. Without the small tubes I could save around 30g, and it would be also a few hours less work.. For my PT2 frame I made it like that and it works of course perfect, but it can take you quite a lot of time to instal the cables...so I made it with small tubes on my PT3 frame, but it's quite complicated and it also adds weight...so I'll go for the WW version this time . Maybe I'll be able to make a new toptube and downtube even in the next few days, will keep you updated..

STUNNING!!!!!!!

@Miller76
Thanks



Some updates about the frame project - I made a new mould for the seatstays, will try to make it in a different dimension (even smaller) and I think this time it will be possible..altough I have to get some new material (probably I'll get it tomorrow), but I still just have enough for the seatstays and will experiment a bit today.

Do it!

Sounds like a really good update.

Go for it and have a great time. Starting your own company is really useful experience, but make sure you have some good people around you.

@sugarkane, billspreston & Tomstr

Thanks for the support
Glad to hear that sugarkane!

Sure, it would be more or less an "one man show". I also have two brothers (one is my twin and the other is 2 years older) and if I would need some more people it would sure stay in our family

I won't rush with it, but hopefully in one year or so I'll manage to slowly start with that. Somehow my aim is till 2013. Of course I'll have to make another frame with the new tubes and present it etc.,... Anyway, I love this work and if I'll manage to start something like this it will be a dream come true!
