Using Salsa chainrings on a Campy-equipped bike

If I wanted to downsize the 42T on my 9s triple to a 40T, am I forced to buy the Campy-branded ones? (Or TA, for that matter.) Salsa offers a 40T with a 135mm bolt pattern, but of course I need to be 110% sure it'll fit before I go ordering one. http://www.salsacycles.com/chainrings.html

Also, hypothetical question... say I wanted to also swap the 30T to a 26T. The Holy Guru says it's OK, as long as you don't crosschain. Is it OK to put a 26T (either Salsa or TA, they both offer that size in a 74mm) with the non-Campy 40T middle ring?

I know this may seem really obvious to some, but I just want to make sure. And no making fun of me for needing a 26T.

If the Salsa ring is really 135 mm, not 130, it should fit properly.

Any 74 mm bcd granny ring will fit Campy triple cranks and a 26T is a feasible swap for the stock 30T. I just did it and it does work fine. You will have to avoid the smallest two or three cogs in the cassette while in the granny but that's a small sacrifice.

The machining isn't amazing on the Salsa rings, but they work.

Great, thanks!

Hillrider, do you have a chain deflector on or is the shifting OK without one?

With the 26t small ring, make sure your front derailleur has the capacity for the larger tooth difference between the large and small rings.

Shifting is ok as is but I have N-Gear Jump Stops or Third Eye Chain Watchers on all of my bikes as a precaution. They are cheap, light and excellent insurance.

To sivat: I don't know of any road fd that has the rated capacity for 27 teeth (53T to 26T chainrings). As you'd expect, exceeding the front derailleur's tooth capacity rating makes the shifts from middle to granny or granny to middle a bit less sharp than if you stay within the manufacturer's recommendations but they do shift plenty well enough.
