CXP 30 Rim--ferrules or??
Back at this--a semi-vintage front to match an 8 speed rear. I picked up a NOS CXP 30 rim some time ago on eBay, and thought that I would need the removable ferrules.
A friend fished a set out of an old rim he had--so I thought I was covered. I finally have all the bits in hand including shiny new spokes, and I take a closer look at the rim--and it looks as if no ferrule is needed (in fact, what my friend sent me it too large for the spoke opening--these were the little doo-dads with the axe-shaped bottoms that fit into the sharp angle of the rim...). A nipple drops in nicely into the new rim and it appears that there is some kind of side/structure to the wall of the hole between rim layers. Anyone know if Mavic changed these rims--and they are in fact spoked up like a standard rim--with no ferrule or washer required? (It actually looks as if there is no room for a washer in the bottom of the hole.) Last edited by paredown; 06-09-2017 at 03:06 PM. |

Post pics.. but I think Clinchers came with them ferrules installed from what I know. Tubulars needed the bag of them... I might be Keen to buy the old ferrules off you if you are looking to unload them..

My first pair of CXP30s had a separate ?lead? insert to match the profile of the rim.
The last pair I inherited had em built in. HTH M |

Here's a photo of a Colorado Cyclist built CXP 30. No ferrules.

The CXP-30 is designed to have a ferrule in it. The first design had a removable one. Mid way thru the first batch they switched it to a built in not that wasn't supposed to be removed and only if you killed it.
If you have the ferrules, put them in. It's safer. If you don't have them, I might have some of the removable ones. I had to make a bunch for the Cosmic and Cosmic Pro/Expert rims. A friend of mine has the Cosmic Experts and has had some of the ferrules crack. So I machined some for the rims. Not sure how many I have tho. |

You just don't see them. Both the clincher and tubular had 'inserts' and both can and did fall out and both were different.

Thanks for the comments. I did want to repeat that the ferrules that my friend sent are too big for the drillings on the rim.
Hard to get a decent pic--but here we are: |

It appears, that your rims have the ferrules already in them. That's the metal that appears to connect the tire bed down to the 'spoke bed'. I'll see if I can get a pic of an empty rim for you to compare..
I have the ferrules somewhere for my spare 28h cxp30 but the 20h cosmic I have laying around doesn't have any, and they are slightly different. I would bet, the ferrules your friend sent would fit, if you didn't already have ferrules in your rims. 🺠Last edited by hollowgram5; 06-10-2017 at 09:12 AM. Reason: Added picture |

Gotcha, Thanks. While I no longer have them, they were solid wheels.Commuted on them for years and other than greasing the hubs I never had to touch them.

Thanks everyone for taking a look. I'm attaching a couple of bad photos of the extra ferrules I have if anyone is interested in them. I have a set of 32. I measure them at about .365 dia, and about .383 from flat to point, and about .323 from flat to shoulder. Last edited by paredown; 06-10-2017 at 01:50 PM. |

I have some interest in them. They are the early style. The ones in your rims are the later style. I'll pm you tomorrow when I'm back home.
