Mystery bits

That is the one!!!

Sometimes I even amaze myself!

are they any good?

Yes, they're good components. MAVIC don't make junk.

also, what tool would I use to correctly dismantle?

MAVIC made special headset spanners for this model. You see them very occasionally on eBay, or if you have a long-established local bike shop they might be able to do the job for you. An ad in the wanted section here might turn up a pair for loan, or there are various dirty methods that might work - a cushioned pair of water-pump pliers, for example, or the boa wrench AR-CoolC suggested.

The brakes look like Campag Athena or maybe Veloce from the late eighties or early nineties. You'll find a picture in the catalogues here:

Those brakes are chorus monoplanar, nice looking callipers..

No they're not. "Monoplaner" (sic) brakes have a slot in one arm through which the other arm passes, like this:

The brake in 1977gti's picture above is a plain single-pivot caliper. '88 Athena looks like a fair match.

Ah yes, right you are..

Ok, so now having trouble finding some cable adjusters for these brakes. The hole where the adjuster should go doesn't seem to have a thread. Any ideas?

It's a hollow threaded rod with a big nut on it, it slides up and down in the hole with the position held by cable tension and the position of the nut. If that makes sense.

Brilliant, I see exactly what you mean. Thanks so much

Ok, me again. The frame has a Mavic bottom bracket. I've taken it apart and it has two cartridge bearings inside (16mm inside diameter, 30mm outside, 9mm width).

Any idea where I can get a replacement. Have looked on a number of bearing sites and can't find one. Any clues?

THESE people were very helpful when I had a request for an odd sized plastic bearing I needed for a tool at work. Very knowledgable and profesional.
