FD Choices

I need some help finding a replacement FD for my wife's 2009 FX7.3 WSD. It came with a FD-C102 for the 3x8 driveline, but has been upgraded to 3x9. The short version of the story is that SWMBO hated the EF60 8-speed trigger shifters. The solution was a set of 9-speed SL-M580 shifters and a 9-speed cassette / chain. It works OK, but the FD-C102 leaves a lot to be desired.

To replace the FD-C102, I need a 9-speed triple FD with 34.9 mm bottom clamp, top swing, bottom pull and a 47.5 mm chain line. I would prefer a 22T front chainring tooth difference rating so I can use a 48/36/26 setup (instead of 48/38/28); SWMBO needs a small granny ring. I did NOT say she is a granny, but.....

The only Shimano FD I have found that meets the requirements is the FD-M510 as used on the FX7.5.

Is the 47.5 versus 50.0 mm chain line critical?

Is there a better solution than the FD-M510?

Is there a simple way to sort through the Shimano technical information to find an applicable part? The techdoc's are thorough, but finding a part based on capabilities rather than part #'s would sure be helpful.


EDIT: Upon further review,.... the FD-C102 is listed as having a 47.5mm chainline, but the FC-M361 crankset is listed as having a 50mm chainline and that is what it measures.

Don't worry about the chainline difference. The derailler can be adjusted to handle that small of a difference. The 22 tooth capacity won't be an issue either. Plenty of guys here far exceed Shimano's specs for road front deraillers without problems. Shimano tends to spec capacity to match what they offer and since most MTB cranksets are 42/32/22, 20 teeth is the stated capacity.

This Alivio derailler matches all of your stated requirements including total capacity and should be more readily available than the FD-M510: http://www.universalcycles.com/shopp...6&category=691

The derailler I linked to is top/bottom pull, assuming the above post is in response to my post

joejack,

Thanks for the response; I was already considering the FD-M430. The FD-M590 (http://www.bikewagon.com/Shimano-Deo...-p9627381.html) is another candidate.
