Unsure of Front Derailleur for LHT build

Hi all,

I need one last part for my green LHT, the front derailleur, but I am not sure what's compatible or worth the price.

Crankset - Shimano Ultegra Triple 6503 52/42/30
Shifters - Shimano BS77 Bar Ends
Rear Derailleur - Shimano RD-M770 XT Long Cage

I was thinking about just shelling out for the Ultegra Triple FD-6503, but I've only been able to find them on ebay, and they go for $40-50, which I don't really care about. No online stores seem to have them though. I have found the 6603 model for sale, but would that work with my 9sp setup?

Or should I just get something cheaper? After all, I'm not really concerned about weight.

Thanks in advance

Any derailer will work. Tiagra is a better triple derailer than the Ultegra, however. The plates are set wider apart and the sculpting on each plate is shallower. This means that the derailer has more range with less rubbing.

Dirtyart, Just a thought, but if you're using this bike for loaded touring you might want to think about lower gearing. Alot of these are set up with intermediate cranksets 48/36/26, or atb 44/32/22. Because if you later decide to lower the inner ring you won't be able to make much of a change with a 52 outer. And going up steep hills the 18-20 inch low is nice.

Here's your derailer

It's only $20 new! There's really nothing wrong with a new FD, but the springs will be worn. New is better. And this one will work well with your drivetrain.

These forum folk know their stuff. Get a cheapo front derailleur, like the one suggested by 'tacomee'. And get smaller chainrings, such as 26-x-46 (the middle one one depends on your rear cluster). Tall gears won't get used much on a tour, but if you're in hilly country, the low ones will.

If you're committed to a triple, get the Tiagra, a brand new one, and deal with the somewhat higher cost. You just got a new, fairly pricey but not insanely expensive bike, which hopefully will last for years and give you a lot of joy, so you may as well spend a bit more and get a FD that doesn't piss you off every time the terrain changes.

Have you considered a compact double instead of a triple in front? I have a triple on my own LHT, and it works reasonably well, but I sometimes wonder if shifting wouldn't be a lot simpler with two chain rings instead of three....

The new 105 Triple FD is fine with your spec. It's wider than the previous but is also rigid.
