Trouble with a new Shimano Triple Front Derailleur FD-5504

I try to change Shimano’s old Double Front Derailleur FD-5500 to Shimano’s
new (2004) Triple Front Derailleur FD-5504 on Giant TCR-2. I got bike with
Shimano 105 group, Triple Crankset, but Double Front Derailleur. All are
105.

The old and new Front Derailleurs are of Brazed-on Type. The old
derailleur was proper adjusted concentrically to the largest chainwheel.
The new derailleur is not adjustable concentrically to the largest
chainwheel, this derailleur matched the curvature of the largest
chainwheel, but front of the bottom of the outer cage plate is much higher
then rear of the bottom of the outer cage plate. So, looks as Brazed-on
Bracket does not match the new derailleur. Is it possible?

How I may solve this problem? I did not get a new Brazed-on Bracket with
the new Triple Front Derailleur FD-5504.

Please, help!

Anything is possible. Maybe you should call to your dealer technica
support or Shimano Technical support. It sounds more to me that the ne
derailer isn't properly aligned. I don't know of any derailer specifi
"Brazed on Bracket" that would result in different tilt alignments

I'm not quite sure what you're trying to say, but let me try. The outer cage
plate is not exactly concentric with the large ring.(I mean the outer cage
doesn't have quite the same curve as the large chainring) The adjustment of
the outer cage is done on the forward part of the cage to a distance of
approx 1~2mm from the tallest teeth on the large chainring. When viewed from
above the outer cage should be parallel with the large ring, or very very
slightly nose in. You shouldn't need a new clamp for the derailleur. Are you
perhaps talking about the differences in the inner and outer cage plates?
The inner cage has a smaller curve to lift the chain from the small to
medium and large rings.

Concentric - Having a common center, as circles of different size, one
within another.

Outer cage in my case has the same curve as the large chainring. But front
is much far from large chainring then rear.

Well then, I think you need to send it back to the seller asking for
refund for a defective new product..............if you really think i
is ..............or you can still call Shimano and ask them about it...
..............or you can try to carefully bend it back so that th
alignment is correct.... remembering that you may break it or damage it
Sometimes the the cage tilt alignment looks "wrong" but as long as th
Pro-set gauge is set for proper height and the stops are set right, th
derailer works. It is hard to tell from here if you have
defective/damaged product. Check out the technical instructions

What is "Pro-set gauge"?

Pro-set gauge is a transparent plastic material that comes on ne
front derailers from Shimano to help you get the derailer set at th
correct height. Looking closely at the sight I previously referenced
you will see it

http://bike.shimano.com/product_imag...FD_5503_SI.pdf

I need to put my adobe accrobat reader at 200% zoom to see it clearly
It shows the tooth profile. Also, new front derailers come with a bloc
that holds the derailer in a position very close to where it will b
when you are in the large chain ring

I still think this is all academic. It sounds like your derailer i
distorted ( bent out of shape)
