Any preferences or suggestions please. I'm thinking of going with the Campy 30-40-50 triple and a 13-26 cassette. Here's my question: the 13-26 cassette can use either the long or medium cage, which would be your choice and why?
Thanks for any info

I think I would always use a long cage for a triple. The cage matters in two respects. First, can it clear the large cog? A short cage would clear a 26. Second, can it take up all the chain slack from the smallest to largest combination (50x26 or 30x13)? I think this is why a long cage is needed for a triple. There is no reason not to get long, unless you already have the medium and don't want the expense; why risk a problem?

You can even use a short cage with a triple. You will loose some small cogs when in the granny, due to inadequaate chain wrap capacith,but if you consider the granny to be a bailout,it isn't an issue. I have several triples,all working quite well with various short cages.I won't claim any advantage,it's just the way I have elected to do it, and I even use to use long caages,but got tired of stocking both kinds.Size your chain so it handles the big/big ok.
Generically speaking, a shorter cage has better shiftingSnowBlind

Your milage may vary. Could you tell the diff? maybe if you jump from a short to a long.

Don't waste your time and patience with the long cage. The Record medium cage rear and the triple front derailleur are significantly slower and less precise than the 20 speed versions. Got them both, use the triple only for hill climbing events. Back to the double ASAP. Agree with Kerry too, the short cage rear could be used but only with the 30-40-50. It would be cool to do a 10 minute quick swap of the crankset and front derailleur to gain the extra low gears when off to Vermont for a hilly as hell ride...

The long cage derailleur is originally meant for using the 13-29 cassette exclusively (better climbing with 2 front blades).
The medium cage also takes the 13-25 and 13-26 (and more?). I would choose the medium cage for more flexibility. For your triple you won't need 13-29 unless you want to ride straight up a wall. Try www.campagnolo.com for more specs.
Good luck. Luke. Amsterdam. www.iwaarden.com
