Quick question: I know that wheel sets can be set up for either Shimano or Campy, but what happens when you start crossing lines for equipment? Can you have a Shimano Casette and breaks, but switch to Campy Shifters and derailleurs? Is this Taboo?

Thanks.

Brakes shouldn't matter but I think you need to kep the drivetrain one or the other...at least the cassette, chain, and rear derailleur.  I really don't know what I'm talking about though

Front deraileur is not too much of an issue as it's not indexed, but mismatching the rear is a whole world of pain.  The indexing is done in the shifter, which is fixed and may (I don't know for sure at the moment) be different between the two, both the spacing between the cogs on the cassette and the distance the deraileur moves for a certain movement of the cable.

I've got a similar problem at the moment because my groupset is an old 7spd shimano, so getting spares is a hastle because none of the new stuff will work on it (unless I replace the lot)

Ahh, now that makes sense. I was curious about the spacing of cogs vs. the derailleur movement. I figured it would be a proprietary issue, but I wasn’t sure. I mean, how much room is there to play with between cogs on a rear cassette.

Not a lot... but 2mm off line witht he derailuer is enough to make that horrible rattling sound of the cog/chain not meshing properly, and it adds up - 1mm too much travel from smallest to 2nd smallest adds up to 10mm out when you get the the largest cog on a 10spd cassette

That makes sense. I have to upgrade my shifters, since they are old and have led a good life, but are now starting to have issues. I have to replace those and the rear derailleur, at least, and am currently weighing my options. I really appreciate your great input.

I'm going through the same deliberations at the moment.  I want to move my shifters from the frame to the bars, but you can't get 7spd shifters any more, so I'd have to get shifters and a new cassette, but then that means a new chain (8spd block uses a narrower chain than the 7spd), which then means new deraileur at the back and new chainrings.  By the time I  get all that separately I may as well buy a complete groupset, but that's £800.  I need a fairy godmother!!

On Ebay, I found these 7 speed shifters, and if you need a different 7 speed casette, i have on on a pair of wheels in my closet. You can have it.
