XD600 with Tiagra Triple Front Derailleur (but what version....?)
I am setting my XD600 (48/36/26) for a 45mm chainline on either a 110-113 BB (have both to try). I see all over the forums that a very popular front derailleur is the Tiagra Triple. I am using DA bar end shifters. I am running a 9 speed chain/cassette.
That said, many of the post on this topic are several years old. People always say "The Tiagra Triple" works great. Until a few years ago the model was called the FD-4403, and this version allowed for a 45mm chainline, a min tooth difference of 10T, and most importantly could handle a tooth difference of 22T (which is what I have)
The new version that replaced the FD-4403 several years back is now called the FD-4503. It still has a 45mm chainline, now has a min tooth difference of 11T, BUT is now listed as only handling a 20T difference (to me this is a problem for my 48/36/26 combo)
I am having an impossible time finding the IRD Alpina D in stock anyplace on the planet or else I would just get it. Avoiding current Shimano mountain derailleurs because of the 50mm chainline.
SO..... Is anyone running at 48/36/26 combo with the NEWEST Tiagra Triple (the FD-4503) or are most people using the older model from a few years ago?
May need to look for old stock on the 4403.... Thanks
