Servicing a Freehub on a set of Campag Atlanta 96s

As per the title, I've got an Atlanta 96 wheelset for my Colnago Dream. The bearings are all good but the freehub is a little rough. Are these serviceable and what's the process if so?

Thanks in advance :)

It depends on what the hubs are - probably the 8s cassette hubs if of that vintage and if they are Campagnolo - the Atlanta was sold as a rim, rather than a wheel set, as such.

If they are the Campag 8s hub with the steel axle, yes, the cassette bodies are serviceable. The outer sealed bearing can be removed with a collet-type remover or it can, with care, be "walked" out from behind with a flat-ended punch (you will need to ease the sleeve between the bearings to one side to start the process with a punch), the inner bearing is retained by a c-clip which needs care and two small right-angle picks to remove it cleanly (yes, I know there are more brutal methods ...).

New bearings simply press in, inner bearing first, then the c-clip, then the sleeve, then the outer bearing, having flooded the area between the bearings on the outside of the sleeve with grease. You might need to make a suitable drift for the press, to plug into the base of the cassette body, to be sure of getting the bearing in dead straight.

We would very, very strongly advise buying "name" bearings (EZO, FAG, SKF, Koyo, etc) from a recognised vendor of bearings (so what is "in" the box matches the name "on" the box, shall we say ...). Generics are often cheaper but the sizing may not be accurate to the ISO standards and frequently they are made of cheese. If the sizes are off they can either be too loose a fit, so eventually damage the cassette body or axle (neither of which are easily replaceable), or too tight and so may bind up when fitted.

Thanks for that. Yes it is a steel axle 8sp hub so that’s great news.

I don’t suppose you know the size of the bearings?

Thanks.
