Well for nearly a year my carbon steed has sat in mums garden shed where I used to worship it.

But its time to rebuild it and take some pics for you.
I cut out the strut running from the headstock to B/B reducing weight by 1 lb 4oz.
I know it looks like a Klien to those diehards.

The cables and brake hoses run through the frame thus keeping the smooth lines of the frame clear.

You are scaring me!!!!

What do you mean you cut out the down tube? Are you trying to compete with the TV show "Lost", and keep us wondering?:-)

Nope I did do it.
I laminate the frame with five layers so I am very confident that it can withstand it.
The headstock was strengthed.
I have raced on the frame since I did it and all was fine.

Hi Dominic, have I missed somethiing here or did you really discard a third of your frame? Mrs Tel likes you as you`ve made me go very quiet for once. I`ve checked the date and your`s may say april but mine still showing november 1st. I must have not read it well hang on......

Nope still reads the same. What with a saw and pointy things? Now I understand why on the 16th of october you were asking about painting carbon, you`ve painted it see through. cut it up with a saw?
Tel
With a saw?

Come on Tel, whats all this about Nov and April.
I have not painted the frame okay.
But it is going for a re-spray in full gloss laquer.
Honest the strut from the headstock to the bottom bracket is no more.
The cables and outers and the brake lines now run through the frame!!!

Its kinda a wierd ride not having that strut there, but worst of all is that I cannot attach a dog poo deflector.

Tell you what when its finished and we meet up you can have a spin on it.

Hey Dominic, I would be interested in knowing what you will use as lacquer. I sprayed mine with a Poly urethane automotive clearcoat which eventually chipped away.

Now my 4500 looks like raw carbon ( unfinished and not shiny)

What lacquer do you suggest I use to make a better bond with the carbon.

Nice to see you back Dom.
and it's good to be back.

When spraying m/cycles and yachts I sometimes spray wet on wet two pack.
But you need a warm room 64 degrees min.
I use an automotive two pack lacquer, just a cheap one.
But if its for flexible parts you will need a plastiser to allow the lacquer to move with the part.

Polyurathene is no good, except in conditions where you may wish to use the bike as a coffee table !!
Your not are you m8 ??
I have sprayed yachts with a poly paint because it durable on surfaces that dont get abuse.
A bike frame takes alot more bashing.

Hi Dominic, stick some pictures on, I cant wait until the meet time, I`ve got to see this mate.
You are brave, what the hell started the idea in you head? How did you know it would work?
Cheers, Tel.
Your sure you did`nt paint it clear.

Tel you should read my threads of a few years ago when I was in contact with K2 I asked them permission to take a mould of the carbon frame.
At first K2 refused then they allowed me to make one.
I am sure Kiwi or Simon has some links to the threads but bare in mind some are very long.
Alot of the work I did I sourced from many of the guys on here for information like Kiwi and Simon, Callum and a few others.
My pics on the gallery show the end bike as it was untill recently.
I work with composites so working with carbon is quite easy.
It was getting the head angles right.
I found that fitting a 100mm fork to the bike upset the geometery of the bike and one had trouble jumping and riding over logs.
I went back to 60-80mm of travel and the ride became much better straight away.
But to be honest the companies have it sorted now and for me to produce carbon bikes would need heavy investment.
I still want to make this Ti swinger one day.

Hey Dominic, you must have been posting this while I was searching the thread out, found it on page 83. I suddenly rememered someone stripping a frame to its bare rib cage and rebuilding it, and it was you. Was this the same proflex? After reading all your adventures with that frame if anyone knows about cutting a frame up its you mate.
So I`ve called off the men with the white coats and butterfly net. Bet you never managed to do the same with the camera you knocked of the bench at the time though smart arse.
Cheers and much respect mate, Tel.
