What the FFD?

Or shall I say: What the funky front derailleur!

Actually I just want to make a post to tell all that my "fancy" bike the one with Dura Ace triple 7703 9x3 speed is giving me fits in the front derailleur department. Last week the derailleur was too low and was grinding on the big ring while in the middle ring. I raised it up but didn't tighten the bolt enough so it slipped down again. I know, all USER ERRORS in the set up department.

So now I've raised to what seems the correct height but angled it ever so slightly to where the back of the cage is minutely out of parallel with the chainring. And my big chainring stop wasn't set so I threw my chain 2 days ago, causing some fine scratching on my 6603 Ultegra triple crank.

So then I set the limit screw while the bike was in the repair stand and everything was looking good, so last evening I did another training ride only to learn that I overdid the limit screw and the derailleur cage is grinding in my top gear.

I've also been playing around with the indexing screw on the head tube that centers the front derailleur differently which then makes varying amounts of trim necessary. I keep thinking I'll happen onto the "perfect" dialed in front derailleur set up.

Well, its back to let out the stop a little and go back to the drawing board! Just had to share.

I'd say you could use a little screwdriver for your training rides. If you don't have one, I suppose a gin and tonic would work too.

Try the set-up instructions found at http://www.parktool.com. Do all of the steps in proper sequence, leave nothing out. They all set up the same way, double or triple.

If you take a little screwdriver on your test ride then you could focus on training on your training ride. Assuming you don't flat on a rusty nail, of course.

It turns out that I had the limit screw set correctly. It was me tweaking around with the indexing screw on the headtube that prevented the FD from reaching all the way out so that top gear didn't rub. I am reviewing the Park Website service information now. I will be reviewing the Shimano instruction sheets for the front derailleur and the triple front shifter.

Thanks for the replies...
