Ultegra 9 or 10 speed Triple front Derailleur Question?
I have a cross bike with Ultegra 9 speed triple.. I just realized that my front derailleur is standard derailleur and not a triple specific.. I am going to be ordering some smaller chainrings which will mean that the derailleur is not low enough to accomodate.
Should I get the Ultegra 9 speed or get the 10 speed front derailleur.. There is not that much difference in price. Are there any advantages to getting a 10 speed front der. I think I remember Sheldon Brown saying that the 10 speed works better if you anything other than the stock 52/42/30 combination..
Any input is greatly appreciated..

I assume you're concerned about the chain rubbing on the cage bottom.
I put a 26-T on my wife's Orbea; all Ultegra 9-speed, and the FD has plenty of clearance.
How small a ring are you looking to use?

I'd judge based on difference in price. Although the 10-speed version may be a bit "better" (a concept that's not all that meaningful in FDs), chances are that you'll be able to find the 9-speed version somewhat cheaper. (eBay)

I want to run at least a 26 chainring on the bottom.. I would prefer to adjust my rings from the stock 52/42/30 to 52/39/26 so there are equal 13t jumps.. I was thinking that the 10 speed may be a little narrower than the 9 speed and may not be suited but was told that the 10 speed works better with a 52/39 combo.. anyone have insight on this?

I'll try this again. I built my wife's Orbea with
an Ultegra triple crank with 52-39-26 rings,
running a long-cage Ultegra 9-speed RD
an Ultegra 11-30 cluster (I removed one of the middle cogs and subbed a 30T from a 12-30 8-speed)
and an HG-90 chain.
Works great.

I have DA Barcon shifters with Ultegra FD and XT Rear Derailleur... I currently have an 11-32 XT Rear Cassette.. It is a 9 speed setup.. I have read that mixing the chainrings would require 10 speed FD..

My wife's Ultegra triple has TA Alize chainrings, 49-39-28. Both derailleurs are the original Ultegra 9-speed. Shifts fine now but required some serious tweaking.
The Ultegra 9-speed triple front derailleur is designed for 52-42-30 chainrings, a ten tooth difference, large to middle.
The Ultegra 10-speed triple front derailleur is designed for 52-39-30 chainrings, a 13 tooth difference, large to middle.
From what I've read in the forums it seems that the 9-speed Shimano triple front derailleurs (other than D-A) work well with the 10-speed triple cranks. But the 10-speed Shimano tirple front derailleurs do not work well with 9-speed cranksets. I don't know if the problem is due to the difference in chainring sizes or the difference in chain widths.
If it was my bike I'd look for a 9-speed Shimano 105 or Ultegra triple front derailleur.

I found a great deal on Ultegra Triple FD.. I am going to try and use 52/39/26 rings, 13t jumps and will see how that works.. If it does not work out, I may try 50/40/26..

I run a 52/42/26 with a Chorus Triple FD. It works fine. The main problem I had were occasional chain drops when shifting to the 26. Between 42 and 26 the chain was essentially high diving and hoping it would hit the 26 square on. I installed an N-Gear Jump Stop and eliminated the problem.

I've made more stuff work that I was told wouldn't work by doing one simple thing... trying it!
