Hey guys,

I'm running a Campagnolo Chorus 11s gruppo with the Campagnolo 11s shift & brake cable and housing set. This is going to be installed on a CAAD10 frameset. I have a few questions that I'm hoping the seasoned gurus on here could help me with:

1. What is the longer grub on the right of this picture below used for? Only one of those came with cable set (pictured). A total of four of the left shorter grubs were included with the cable set as well.



2. I'm in the process of installing the 4 smaller grubs on to the shifter cables: three for the rear derailleur cable, and the last one for the front derailleur cable. I'm not installing any grubs into the shifter body itself for both the shifter and brake housings. Again, as stated in question 1, I don't know what to do with the longer grub. Is this correct?


Any comments, suggestions, and or insight directed to the questions above would be greatly appreciated.

Thanks!

I believe the longer one on the right is used on frames where the housing stop on the chainstay is just a small loop where the narrower part fits through. Older frames had this style of housing stop on the chainstay before the full length ones we see today appeared on frames.

I am not too familiar with Campy as to whether of not you install the housing ferrules (not grubs) on the side of the housing that enters the shifter or just leave the housing naked. The manual or someone else on here will know the answer.

I cannot see the pics from work, but I am guessing the things you are calling 'grubs' are the metal cable-housing ends, and they are more correctly caller "ferrules."

+1 This would be my guess as well. I have them on a few of my frames at the front of the short cable connecting to the rear derailleur.

Thanks guys--ferrules, not grubs... got it.

Does anyone with Campy 11s experience know if I need to be installing ferrules on the housing ends that are being inserted into the shifter body?

It doesn't hurt if they fit.

the stepped ferrule would be handy If you were throwing money
at a 70s Classic frame,
and putting one of those 11 speed sets on .

The 'Divers Helmet' braze ons of that period would need to be using the stepped down housing end.
