Front Derailleur recommendation
Hey all,
My commuter/touring/utility bike is currently set up with a triple crank up front with the granny removed 'cause I didn't have a front derailleur with a long enough cage to accept it.
I've been carrying bigger loads on it lately and I also intend to get a trailer soon so I'm wanting to put the granny back on.
Looking at the shimano site, it appears all the new ones only work for 22T range. I'm running 24-48 so I'm curious if anyone has tried this before and made it work. I've got a 7sp 11-23 on the back if that matters.
I'm looking for something around XT level but I'm open to suggestions.
Thanks!

I used a Shimano 105 with 48/36/24 for awhile, no problems at all. My front shifter on that bike is friction. Sounds like you may be looking at "mountain" derailleurs (does your cable routing require top pull?). I think the Shimano FD's in the LX or XT line, shaped for a 48t big ring, would work fine with a 24t difference. I'm talking about the LX or XT models that go along with the touring/trekking cranksets. For that matter, I would think one of the standard Shimano "mountain" derailleurs would work fine with a 24t difference, but the cage would just be shaped for a slightly smaller big ring-

My front shifter is friction as well (running old Deore thumbies)
Bottom pull, 28.6 clamp
What's the model number on the 105 you were using?
Do I need to worry that a new one designed for 9 or 10sp will be too narrow to accomodate my 7sp chain?
Edit- I was looking at mountain stuff but I'm currently running an old road FD and I don't really care as long as it works. It's biopace too if that makes a difference.
