Replacement cables for Campy

[jemoryl]

I'm running 11 spd. Chorus on one of my bikes with the original Campy cable set. It has been said that using the Jagwire 1.1 mm dia. inner cable as a replacement for the 1.2 mm dia. Campy cable can improve the shifting on the rear. I'm going to try this when my cables need replacement, but I'm not sure what kind of improvement is possible, given that shifting with the 1.2 mm inners is fine. Apparently this doesn't matter as much for 10 speed Campy (I have a couple bikes with this) and I don't know about 12 speed.

To be honest my rear shifting was not the best. So I'm open to other brands for sure. Also put on new bars and hoping a cleaner routing of the housing will help the shifting. Have Jagwire on another bike and have been pleased. Also, would Shimano work? Appreciate the help as always.

Jagwire slick stainless are great BUT a couple of suggestions.

-CUT the 4mm der housing CLEANLY and make sure they are LONG enough.
-Make sure the wee brass washers that the housing psuheds against arein the lever der housing holes..and not turned sideways or missing(ask me how I know)
-Route the der housing behind the handlebars-seems to make for better shifting
-wee bit of grease on the while delrin ramp where the inner wire leaves the lever
-use 5mm der housing at the rear der, long enough, with metal(brass is best) ferrules.
-NO ferrules in the lever..not for brake either
-ensure under BB guide is plastic and clean, smooth-metal ones are draggy

Campag ERGO 11s/12s DEPENDS on very smooth movement of inner wire.
You mentioned Chorus 11s..early model? White take up spools? Might need the upgraded black ones..a running change.

Well im glad i read this. Getting ready to do my first 11s campy build and:

a) didnt know theres two routes you can go on the derailleur cable.
b) i only have 3 out of 4 wee washers. One is missing on the route to go behind the handlebar, so gonna attempt to move the inner one there. darn hard to get to though.

a)-yup..
b)-I have these if you need them...yes, you can fish them out..but they are essential.

I am pretty sure my group is 2015. Wee washers are in place.

I used Jagwire on my latest build and it shifts like butter. I have no experience with Campagnolo cables so can't speak to that.

As mentioned by others, the head at the end of the cable isn't the same between Shimano and Campy. Campy is smaller, and if a Shimano-spec cable is used without grinding down the head first, it either may not fit or it may fit but be so tight to get stuck.

The other thing - Shimano shift cables are 1.1mm thick and Campy is 1.0mm thick. A Shimano cable will fit in a Campy housing, but since that cable is a tiny bit larger, there is some resistance when it's in there. ***I haven't looked at any of these specs in 5+ years, so somebody correct me if this info is out-of-date.

So be careful if buying non name brand stuff, they don't always get these specs correct. Once I did buy an off-brand cable that had a campy head but a 1.1mm thick cable.

Got it moved over! And I pulled out the unused one so it doesn't get lost.

Haven't measured but I think 1.2mm for shimano and 1.1 for others.
shimano head won't get stuck in the spool of a 2009, 11s, lever but may drag on the inside of the lever body as the spool rotates. It WILL get stuck in older, 8/9/10s levers.

All my experience is with pre-index stuff. I'm used to having to take out the Dremel and grind down the heads of Shimano-headed cables to fit in my Campy shift levers. Not long ago, I acquired a set of Campagnolo Doppler shifters and installed them on my Griffon. Imagine my surprise to find they accepted Shimano size cable nubs without grinding...

Since I was sitting here next to a tool box with my calipers, so I went over to my bike and measured 1.2 mm dia for Campy "Ultra-Low Friction" cables, 11-speed era. An older bike with a set of 10-spd. era cables has inners that measure 1.3 mm, BTW.

I went to the closet and found that the 1.1 mm Jagwire inners are indeed 1.1 mm, as are some Kble cables (made by Transfil in France), which are actually billed as 1.2 mm on the package.

There ya go..BUT, as has been mentioned, 1.1 with a proper Campag head can only help to keep the system smooth...

Well all this talk had me curious so I popped open my set of campy cg-er600 and I noticed..... What the heck is this thing? And how do I make it work? In particular to the left of the ferrule. How does the skinny part go into the cable housing? Or is the ferrule on there backwards from the shipment?

That rubber accordion goes over the hard plastic sleeve sticking out of the ferrule, not inside the ferrule as pictured. Helps seal out the dirt.

The first time I got one of these, I was little confused myself, until I realized that the rubber grub seal was only stuffed into open end of the ferrule for packing. Pull them apart, and then install as stated above (the grub seal is first slid onto the cable, the ferrule is installed with the extension passing through the cable stop, and then the grub seal is pushed over the end of the ferrule extension).
