Front Derailleur Shifting Problem
I was gifted a 2007 Specialized Sequoia Elite in lightly used but poorly stored condition. Everything seems to be original except the original drop bars were removed and replaced with a comfort handle bar and mountain bike shifters. The rear derailleur indexes and shifts fine but the front derailleur does not. The Sequoia road bike front derailleur is not compatible with the mountain bike shifter. I can kind of make it work but basically the shifter is difficult to operate and the indexing moves the derailleur too far each shift. Obviously the shifter wants a longer actuator arm on the derailleur.
The 2007 Sequoia came with a triple front chain ring which I want to keep. I also want to keep the comfort handle bar especially after reworking the shifters and purchasing fancy grips and bar ends. The Sequoia seat tube is 1-1/4” diameter and the derailleur pulls from the bottom. I’m thinking the easiest solution is to get a mountain bike derailleur if I can find a correctly configured one.
Any good/better solutions or suggestions will be appreciated.
Thanks.

Can you name the shifter (alivio, acera, deore etc) and the FD (tourney, claris, Sora etc)?
Also how did this bike end up with an FD that's incompatible with the shifter? Are you saying that in came this way stock?

The front derailleur is a Shimano Tiagra Triple and the shifter is Deore. The previous owner modified the Sequoia and I don’t have the replaced parts.
I last rode in the 80s and my last bike was an 80s Rockhopper so my knowledge is way dated. I live near Placerville CA where it is way hilly so I use the triple. My first bike is a Tricross so I prefer an inexpensive fix on the Sequoia.
Thanks.

Shimano produces a flat bar indexed front shifter control that is road bike der compatible. If I follow the issue correctly this would be the slickest solution, other then gong friction for the control lever. One could use a Micro Friction Grip Shift too if grip Shifters are your bag. Andy

Do you think you could do some Google-fu and find out the exact model of the FD? It's either 4500, 4600 or 4700 I would say. I believe there was a change in pull ratio for 4700 so unless you have 4700 I would go for something older/lower like sora.

Road shifter has been replaced with mountain shifter which is incompatible with factory FDER.
Shimano has a FDER that matches them up.
Something like an FD-R453?

The issue is road & mountain shifters pull a different amount of cable.

- "Designed to be used with SL-R440 or SL-R600 shifters only"
- Those are flat bar road shifters, not mountain bike shifters

I think we're overcomplicating this. We just need either a matching mountain FD or a matching flat bar road shifter. Those are both dime-a-dozen for like $30. This should be very, very simple if we can just get an exact model # for either the shifter or the FD.

I installed the Deore XT fd and the indexing seems right so I’m going to leave it at that. Thanks for the assistance.
I created another problem as I changed cassettes on the same bike. I went from an 11-28 to an 11-36 for the local hills and for therapy on my gimpy knee. Now the rd idler interferes with the largest two cassette sprockets. Don’t know what to do except to go back to the 11-28. I’m enjoying learning this stuff so I’d welcome assistance on how this should be addressed. Thanks.
