Overhauling my 1995 Campagnolo Chorus hubs

the_one_with_the_big_wang

I'm replacing the worn parts of my Chorus rear hub and was wondering if anyone could help me with identifying a part a nearby bike shop recommended I use as a replacement for an old part. It is a Left Cone part no. FH-RE107. Below are the pictures illustrating the difference between the old part and the possible replacement. Clearly one is longer than the other yet they both have the same number on the back 10x26. What are those numbers referring to? Is the replacement designed for a different axle length or from a different year. Nowhere in Campagnolos parts catalogue can I find this longer cone, that is unless the shorter one (my original) is the odd one.

Try speaking to the guys at mercian cycles as they know alot about campag

I think the 10 x 26 is just referring to the diameter / pitch of the threads, nothing to do with the overall dimensions of the cone.

Looks to be only a couple of mm in it; is there a spacer / washer you could lose from somewhere else? Alternatively do you know a friendly lathe operator who could shave the difference off the non-business end?

I could take a washer away from the drive side which will leave a springed washer between a cartridge bearing and the lock nut but then the wheel will be offset slightly. I'll call Mercian tomorrow but being 200 miles North of me could pose a problem. I'm going to visit three shops in the morning a couple of which are Campag pro shops so hopefully they will have the parts in stock but they are rare as hens teeth so will really need to keep my fingers crossed. I'm desperate to get my baby back on the road.

I don't know a friendly lathe operator unfortunately nor a non friendly one come to think of it.

They probably changed the part design in response to failures like yours - if you can miss out a spacer / locknut you should be OK. 10x26 is indeed the thread size. FWIW cones are made from hardened steel and then bearing race is precision ground, so unlikely that a general machine shop would be able to make you one cheaply.

I wasn't suggesting he gets one made, just shave a bit off the outboard end of the chunkier part he's got.

Although your point about Campag beefing up the part is probably spot on, so that's probably not a good idea.
