Cable Guides

[bigflax925]

Ok, my Pinarello cross bike has some funky cable guides and it's making for a tough build.

What sort of cable housing ends should I be using with these guides on my brake and derailleur cables?

I remember the old slinky-style stainless rear derailleur housing on Campy Record. I don't have any to try, but I recall it had tiny little ends that might fit these guides?

Any insight or direction on what to use?

I swear, I'm gonna sell this thing before I finish building it, as every time I turn around there's something I haven't accounted for! :bike:

What happens when you take the cap off the housing? Still too big to fit through?

Are these housing guides or stops? If they're stops, then you use housing caps that have an extension that fits in those holes. Bike shops usually have them.

Yeah, those. ^

Those are the ones...step down ferrules...just put one on my '89 Pinarello Treviso RD cable tonight.

Awesome, guys, thanks!

Incidentally, this is a 1989 Pinarello, too.

Maybe I'm missing something. But shouldn't the cable pass all the way thru?
The step down is used at the rear deraileur from the chain stay to the RD.
I don't see how this helps on the top tube cable guide. Maybe you are going to run bare cable like a split bullet stop on the side of the top tube.
Can you post pictures when assembled? Always trying to learn.

I'll post pics if/when I ever get done! However, the bike only has cable stops on the top tube - for both brake and rear dérailleur (which runs down the seatstay with a couple more stops for routing). Rather than full length guides, they are setup to split so the cable is exposed between them. All of the stops need these step downs.

There's also one on the left of the down tube for a front dérailleur.

Or a local bike shop. 50% step ferrules.

You're not missing anything, the pics are confusing. Basically it will be set up like this one below only his will be using step down end stops to work with his open end braze ons.

Are you sure it's an '89? The Pinarello catalog shows different stops for that year. They were still doing guides vs. stops.

How large are the holes, will the cables fit through them? some cross bike from that era still used guides to keep gunk off the cable, vs exposing the actual cable.

'89 cross with guides:

The holes are not large enough for housing to pass through.

Actually I used Mark's catalog scan to narrow it down to an '89 since mine is flourescent yellow with Oria tubing. But I do see what you're talking about guides vs. stops.

I looked back at all of Mark's scans and it doesn't look like there's a cross bike cataloged in '87... so I guess it could be a 1988 or a post 1989?

Or they mocked a frame up for a photo shoot?

There's so little out there on these it's hard to get any sort of info.

[sean]

Especially Italian bikes. It wasn't uncommon to change something mid year and change something back.

The thing I find odd is that those stops are Cinelli Diver's Helmet Stops. Usually seen on chainstays. You can see how they are butted together on your frame.

Everything else looks normal for that year. I wonder if this was a later mod done and the original guides replaced with stops. Or maybe a custom order?

[bigflax925]

Interesting. Yes, that's the stop.

I don't think it's a custom job, as I just ran across this one, which is the same in every way other than size.

There was a period when Pinarello was making rather funky bikes. I've seen those before and they do need the step-down ferrule. They chip and rust quickly and in every example I've seen, there was lots of flux still around the base of the stops and in between so they actually rusted out even faster. If you decide to get a paint job at any point, get rid of them. You can get 2 and 3 cable versions in stainless that will never rust and work better.

By the way, if you can find the leftovers from some Gore Ride-on cable kits at your local shop or from fellow riders, there are some very nice bits that come with them that work here too, and also have a grub seal to keep dirt from getting into the housing.

Those crazy italians. And people complain about the french!

Either way, great bike. If you get too frustrated, send it my way, I'll set it up (ride it a bit) and then send back. :beer:
