how can i adjust my ultegra lever so it works for triple cranks? is there any internet-link? or does somebody have the manual?

You don't have to do anything to the shifter. As a double you get two shifting positions for each chainring. As a triple you get one position for the granny, two for the middle and one for the big ring. Getting everything set up correctly sometimes takes a little fussing, but it works fine.

wow, thanks. so, once again: all i have to get is a triple front derailleur, instead of the double (i found it out when it didnt work)

And you'll also need a triple rear derailleur and triple bottom bracket.

Triple rear derailer is not an absolute requiement.Particularly if one limits the small cogs when in the granny.

When you brain fart, shift into too big a cog, and bend the small cage rear deraileur you'll have the opportunity to re-think your decision when you buy a new one. Been there, done that, wasn't fun.

Sorry not to follow your thinking.Use the big ring and next to biggest cog often .No problems.The derailer will shift the big cog no problem and the chain is long enough for that combo.Even the short cage will weap all of the few smallest cogs on some cogsets when in the granny. The long cage wraps chain.What am I missing.Maybe you had some other brainfart.

perhaps a b-screw adjustment error? that could cause 'intimacy' between the jockey wheel and large cog

As long as the chain is long enough to cover the big/big combination, you won't have that problem. What will happen is, if you try to use a too small rear cog with the granny, you won't have adequate slack take up which will probably make funny noises and remind you to shift up to the middle ring.

Right on.I use short cage on all my road triples.No problems.Granny is just a bailout.

I was under the assumption that you'd set your drive train up such that when in the small/small combo there would be *no* slack in the chain as is the norm. When you then accidentially shift into the big/big combo you'll lock up your drive train and bend your rear deraileur.

I guess I can't figure out what you gain by not using the rear derailuer designed for the tripple drive train when one considers the compromises that must be made, but hey, that's just me. ;-) I tend to brain fart a bunch on long rides that feature lots of vertical where a triple would actually be required.

I never considered setting the chain length on the small/small the norm. No comprimises from where I sit. The granny is a bailout and no need to use the small cogs when there.Besides I save a few grams and can use a nifty DA 8 speed rear deralier on my 8 speed setups with 9 speed bar end shifters.Freaks people out.Just different strokes.
Should work fine! n/mcurlybike
