it's a shame what people do to nice frames, i was on ebay last week and saw this and forgot to make a post, take a look at the pics . It's sad.

feel free to post any other sad cases...

Being that the cable routing on both brakes and derailleurs is internal, this may have been a factory job.

Interesting that the paint around the threaded studs is not burned, which leads me to believe this would have been done prior to painting. The loss of paint around the cable hole is probably due to cable rub during shifting.

When I first saw this on Ebay, I thought the same. I've revised my take on it; I don't see that the approach saves much in the weight department, however.

I think its a factory job.

but what about the de-railleur, it looks hacked up.

and the bolts coming out of the tubing, that's hideous

miamijim

How else would you run the cables internal?

I've seen a bike with similar cable routing in person and its kind of cool to see. I'd imagine there's some type of guide inside the BB.....

Appears to be factory work... the internal cable routing does make things .001% more aerodynamic and leaves some clean lines.

Once the bike has cable housings running into the tubular guides on the frame they will not look as hideous.

I had one of Zinn's first frame awhile back, and the PO had drilled into the frame really shoddily (is that a word?) to run his cadence sensor. Always a bummer. You can't undrill a hole

Capecodder

It looks to be a factory job indeed..... No way would anyone be able to weld those bolts inside the tube without destroying the paint. Then again, they could be epoxied in place. This gives me an idea

streik

I actually like this... a lot... am I the only one?

I like it too. I have similar routing on my Land Shark. Gosh, guess we can't whine about this one.

Whew, that's a relief! I saw this thread title and thought someone had seen one of my bikes!

Sixty Fiver

You can "undrill" a hole... with a torch.

Tends to mess up the paint a little.

auchencrow

It might be factory, but IMHO the title of the thread still applies.

Otis

I think it's totally cool.

hahah funny...

if it is a factory job, you'd think they'd do cleaner cuts and drilled holes and whatnot, it just looks like my 4 year old cousin got ahold of a drill and the frame and did some practice tool and die

I assume it's factory and it's made to mount that weird-ass front derailleur. It looks like he just pulled the front derailleur off briefly to show how it mounts and you can see it mounted in the other picture, look at the picture below. His notes say:

Note: unusual attachment of the Campagnolo front derailleur, see picture 11 and 12, I've never seen before




Anybody ever seen a similar front derailleur? Looks like a horrible idea, how do you remove those bolts from the inside of the seattube without going down from the top?

Roll-Monroe-Co

I think this is really interesting. How are the bolts held in place? Can they be removed and if so how? Is that drilling (both frame and dr) factory or not? I think it looks tremendously cool, and the idea is rather obvious, and the attachment is quite elegant as long as you don't want to change anything.

Has anyone ever seen anything like this before?

with the front brake hidden inside the fork crown and blades.

Otis

Don't know what you guys are looking at, but this a cool attempt to get rid of the der clamp pre "braze-on" and run the cable inside the tube. The hole looks like a piece of tubing has been brazed inside as a guide. If your 4 year old cousin is that good now he should be something when he's in long pants.

pictures?

I think (read that as "know") I could do a much better job with a drill. I mean, use a file to start a flat spot that a larger bore drill bit would round out perfectly. You could probably get it more perfectly oval too by angling the drill bit ? Clean up any rough edges with a file and paint the frame if it's factory, touch up if it's a custom work shop job ? Some of these high end frames that I've seen have some really good work done for the top tube, yet when the down tube or other areas are done, the work looks like they turned a 12 year old with his father's Craftsman power tools loose on it ?

Sixty Fiver

Have seen this also... pretty amazing work.

Otis

This thread just keeps getting funnier.

I can understand that and I guess it makes sense if this was just a one-off 'show' bike since it's a pretty interesting design quirk (it has had all of us talking about it here) but I can't understand what practical application this would have.

Was that a production campy derailleur? I don't envy the person that needs to replace that front derailleur if it fails or even the person that needs to run a fresh cable to it.

I guess I just like standardized clamp-on derailleurs and I'm not into the braze-on derailleurs anyways (since I don't have any in my parts box), so grain of salt etc.
