Im from Australia man. Theres no such thing called Craigslist here.

Not gonna sell this anyway. Frame and forks are holding up fine, and feel stiff as! Much stiffer than my rusty Peugeot Izoard. Reached over 60km/h and everything is fok at the moment.

Oh, those with this same frame, how did you use the cable guide/stop for the rear derailleur? My housing is slowly slipping though the hole. Should I drill a larger hole to fit the housing furrule? Or am I doing something wrong?

Use a ferrule to keep the cable housing from slipping through and getting messed up. The hole towards the front of the stop should be smaller than the front to start with, and should keep most cable housings from slipping through, but if there is a problem, a ferrule should fix it. I use them on my Vitus Carbone and my Alan Carbonio, but the same should apply for most bikes....CF or not. Do not drill the stop. as you should be able to find a "reducing" type ferrule to fit into it. A good bike shop should have a selection for you that would work.

Thats the problem. The cable stop has a hole that fits only the housing. It wont fit a ferrule. Thats why I wanna expand the the back side of the hole so that it can fit a ferrule and leave the other end as is.

QV, Bike looks Excellent. I appreciate a drop-bar riding position.

I think the RD stop fits the housing, and not the ferrule, because it's designed for a step-down ferrule, which is kind of loose in there, but that's what it's supposed to be. I'd get one with a longer nose, if possible. If not, the Jagwire kits recently have some graduated smaller end ferrules, and I may be able to ship a couple Down Under for you.

YES!.........and please put down the drill!
Please also note that they come in different sizes, so make sure you get the one that works for your brake cable casing and frame cable stop.

Better head over to the LBS then. What should the approx price be? I know some bike shops here would rip customers(a certain one wanted $10 for a shifter cable!)

Mavbe 50 cents to a buck max each. Anything more, I'd look elsewhere. They are still made and are used by bike shops to service brakes on bikes.....sometimes I even get things like them for free when the store manager or mechanic is feeling good that day I ask for one.....
BTW, if you haven't yet, try to establish a good relationship with your local bike shop as they can usually also help you with all sorts of questions you might have on you bike, especially if the shop have mechanics that are familiar with older bikes.

I dont often buy parts or many things from my LBS. Thats mainly because I dont often need parts, or the parts cant be found new.

But will see what they've got tomorrow. Oh, its Anzac day. Will have to wait til Friday then

I love this project!

You are a brave man drilling holes to internally route the rear brake cable. I do agree that the holes probably won't hurt the frame's integrity, but I'd worry about water getting in there.

Keep the pics coming!

I dont ride in rain as I become all muddy, etc. Its unlikely that water will get in there, as the housing fills the holes nice and tight. Also I dont think water will pose much of a problem to carbon.

Will get more pics once the bar tape arrives. Hopefully tomorrow. And once I get the tape on, Ill finish off the cost and weight list. Hopefully I have been able to stay under 10kg.

Guys, I have a Cadex fork from the first year of production available for the price of shipping if you want it. Came from a 54 or 56cm frame. I used the frame to build a bike rack for the motorcycle. I can measure the steer tube if needed.

Just so you know, the tubes on that thing are very thick and drilling for cable routing should not present a problem.

Disclaimer: This is my opinion and not fact and not researched. I do not recommend, nor condone any modification to any bicycle frame at any time.

Yep, the top tube is approx ~3.7mm thick.

What is the steerer length on that? Id be interested! Please email me, as I cant PM yet.

Yes, a lot of C&V CF tubing were quite thick and almost look like over-engineered thick on some bikes. One of my C&V CF bikes even have internal, thin guage aluminum tubing backing up the CF material. It's just a lot of people think that all CF on bikes is as thin as the stuff you see on modern CF monocoque framed bikes, thus the mostly unjustified fear of frame "asplosion" with C&V conventional shaped tubed CF bikes. The old frames are more likely to fail at the joints with glue bond failure than actually fracturing at the tube's legnth....I'd still try to avoid or minimize any drilling of the tubes though, if you can....

I picked up a 980c a couple weeks ago. Really nice riding frame. Compared to my vintage steel, the bottom bracket area feels very stiff. I really like the ride, even with the aluminum fork. Not a bad way to spend 75 bucks!

The drill had been picked up again! Called all the bike stores around, and 90% didnt know what I was going on about. the few that did, had to order it in, and I need one by tomorrow. Chose to drill the stop 3/4 of the way in with a 5.5mm drill bit. Was drilled at a slight angle to allow for the housing/ferrule to exit and not hit the frame.

And weighed the bike today, coming in at ~8.8kg like pictured up above, but with 2 bottle cages(1 plastic and other metal). Not bad considering I didnt go and find the lightest parts I could find. It was the cleapest parts.

That wouldn't surprise me at all. Same thing happened when boat builders moved to fiberglass in the sixties. As they didn't have much experience with the stuff yet, designs were often over-dimensioned, just to be on the safe side. Many of these first generation yachts are still around, and virtually indestructible.

After a mishap from Wiggle, I finially got my bar tape. USE Alien carbon seatpost arrived today as well.


Now, I thought more expensive and branded tapes would be better. To me, it seems worse(thickness and softness) than $2 Chinese tape.


Compared to this tape that came with no adhesive tape(actually prefer no adhesive). It was thicker and produced a ribbed feeling.


Seatpost in


And a pair of carbon cages, just to finish it off.




Will get the bike weighed and component list finished up soon.

I think you could drop some more weight with a different crank. Great looking bike btw.
