Has anyone converted a Casati with the internally routed shifter cables and the Campy levers mounted mid tube to a brifter type set up? If so how?

thanks

Don't see what the problem would be, if there are down tube shifter bosses.

that is the question the shifter boss is mounted mid tube, not on the sides and the shifter cables go from the shifters directly into the down tube..... the rear shifter exits out of the drive side change stay and the front shifter from the rear seat tube bottom bracket area

Index shifting presents a problem with the top of the DT shifting arrangements. In order to get my 7s DA to index and not keep getting out of adjustment (on my Motta), I had to run cable housings for the rear inside of the DT and chain stay. The front didn't care. You'll have to deal with the cable run from the DT cable entry point to the shifters. I had a 1/2";, yours will be extending to the bars.

If the arrangement is what I'm thinking it is, it seems that you would need a cable end (ferrule), that has an angled end for where the cable enters the downtube. I've never seen one..Probably easy to make if you have access to a small lathe. Otherwise very expensive if you pay a machine shop to make it. The other option is to bypass all of that with clamp on cable guides and stops.

I ran shimano 8 spd down tube shifter (indexed) as well as sti on my Casati without any issues. I don't under why you are having problems.

I believe the OP is asking about cable stops for aero style braze-ons like a lot of Casatis have.

whatwolf is correct so here is pic worth a 1000 words I don't have a casati, but have been interested but many of the nice ones are set up this way

shifter



front derailer cable



rear derailer cable

I've seen folks make 'homemade' cable stops using DT shifters that work just fine.

Don't over think it.

I am not sure how that would work in this case.

I don't think it is practical to convert that to an index system. I suspect whatever you do to get housing stops and get the cable running into the holes will cause too much friction. The only practical way to do it is to use a clamp on cable stop, like problem solvers. But then you also need bolt on cable guides.

That looks like a nice frame, if you can't enjoy it with that great escargot style setup pass it along and get something more conventional for your brifters.

Wrong on so many levels.

It sounds pretty right to me. Please explain what do you mean by making "homemade" cable stops out of down tube shifters?

Looks just like my Gianni Motta routing.
One of the reasons this arrangement disappeared with the introduction of index shifting mid 80's is the issue I stated (and resolved) about keeping it all in adjustment in my earlier post.

As far as routing cable into the DT, I'd probably run a clamp-on double cable stop right in front of the "escargot". But it's not going to be real elegant at this entry point.

I've seen Dremeled DT shifters used as cable stops. Making the stop is not hard, nor expensive. Whether the cable friction with internal routing is insurmountable or not, I have no idea. One could always go EPS or Di2. Problem solved.

OK I do agree you can hack a old pair of DT shifters and use them as cable stops, it doesn't look great but I understand how it can work. How would you do that in this case?

The cable and housing would have an odd extra loop or bend to get them pointed in the right direction to go into the modified shifter and into the guide tubes inside the DT. I think this would cause undo drag on the cable and make shifting sluggish at best.

Do run the cables in any other manner requires clamp on cable guides.
