I might "Drew" my Coppi...

OK, now that I've got you attention... I made a thread a while back on this bike, I'll hunt down the pics later. Right now it's serving as a fixed gear while I collect and decide on parts. It's an early 70's Coppi Milan SanRemo (not the Super) made by Fiorelli. It seems to be rather low-end, so I'm not overly concerned but doesn't mean I don't want to treat her right. Here's my dilemma - The derailleur cable routing is a bit non-standardish- a piece of tubing for the rear and a cable stop on the lower down-tube for the front. This means it should have a FD with a cable stop to match.



Here's my options as I see them:

A) Leave her "fixed" and don't sweat it. She make a pretty cool "beater" anyways.

B) Use a Gran Sport FD. Probably OE and the cranks and brakes I've gathered are also GS. I've never used a push-rod type FD but I just can't imagine I'd like it much. However, they've got a cable stop.

C) "Drew" the braze-ons and use a clamp-on type guide or braze on new over the BB guides. This would allow me to use a NR derailleur and I kind of like the idea.

What are your thoughts?

Bonus question: Anyone ever heard of Z-50 "light wieght steel tubing"? It's seamed and takes a 26.2 seat post.

I never Drew a frame or a component, but that is a personal choice. In this case, it is a no brainer - get a proper derailleur and try it out before you permanently damage the frame.

The push rod derailleur will not perform as well as its Newer School counter part, but it will work just fine. I have owned, built and ridden many bicycles with the push rod derailleur and had no complaints. I should qualify that by saying that I stopped comparing Old School technology to New School stuff years ago.

You can route the front deralleur cable under the bottom bracket. Use a piece of cable housing from the downtube stop long enough to go under the BB and come up behind the seat tube between the chainstays. Works well and you can use a frt derailleur without a stop.

No problems running a cable to the rear derailleur.

I'm actually in the same situation with an old maino frame. I looking forward to building it up with old gs derailleurs. I have to use clamp on guides for both derailleurs also a clamp on stop for the rear on the chain stay.

+1. There are also other FDs with built in stops. I just built up a Bottechia Pro with a Suntour (BL?). All aluminum, with a built-in stop. I'm building it with Suntour barcons and had an appropriate Suntour downtube stop in the stash....

You can also buy a Campy 2-sided cable guide that clamps on, and you'll not need a cable stop for the FD. It also routes on top of the chain stay.

I have a one sided FD campy clamp-on guide I could be convinced to sell

Also, where can we see a pic of this bike in its current FG config.?

Thanks for the thoughts/ideas so far.
I dug up the first thread on this bike:http://www.bikeforums.net/showthread...nt)?highlight=

The clamp on guide is option "C", and the most likely route if I do cut off the current braze-ons. I know other derailleurs have stops. I've got a cyclone that would do the job but I'd prefer to keep to it's Italian "heritage". I don't really see it as "permanent damage", more like an upgrade. I hear of people adding water bottle bosses and the like all the time to make a bike more to their liking. I'm mostly just exploring my options. For the time being it will remain a fixed-gear "beater". If I were to return it to a geared ride, I'm afraid it would fall into redundancy and not get ridden. Add to that the cost of decals and paint I'd want if I go "all the way" with it. I'll try to get a couple pictures taken for you guys. I'm trying a pair of riser bars on it but just don't like them to much- feels like a big kids BMX .

I vote for drewing it. I mean, what the heck! I have the same brazeons on a Falcon frame that I ride every day, and it's built up with a Sturmey Archer 5 speed hub, so the little cable stops are not in the way. No big deal. But the paint on that frame is absolutely shot, and there are no original decals, and so on. One of these days I may paint it, or have it painted, and if so, my first step will involve a hacksaw and a metal file.

I would choose option B, Campagnolo Gran Sport. Of course you could always buy an early Record front with the cable stop.
The imaged alternatives will work, but do not "look" factory.
