Do EZ Fire allow fine adjustment for the front derailleur?

Hello,

do "EZ Fire" levers allow fine adjustment for front derailleur?

I have revoshift levers on my old MTB (grip shifters), and the front one has "clicks" for fine adjustment of the front derailleur. E.g., if I shift from the mid to the outermost gear of the rear cassette, the chainline would move right and drag on the front derailleur, so I would go one "click" up in the front to re-set the front derailleur in the right position.

Is this possible with "EZ Fire" levers?

I think at least in the Shimano world they refer to that function as "Trim".
That might help find what you're looking for.

Thank you Barry for your help, indeed from what I reckon online, EZ Fire shifters have no trim function for the front derailleur. I wonder whether this means accepting some chain dragging in some gears, or maybe with the right derailleur and the correct adjustment, there's no chain dragging and no necessity to trim the front derailleur, differently than in my revoshift equipped MTB.

When I was mechanical, I used Trim to avoid chain / FD contact when cross-chaining a little more than I should.
I didn't need the Trim function during recommended operation.
Another way of explaining, when in the big ring, I could get to another larger cassette cog through the use of the Trim.

If you are cassette small cog and having to trim after changing to big ring, I'd say the adjustment is off.

MTB left trigger shifters don’t have any trim. I don’t think the flat bar road left shifters have a trim function, even though the same (Sora, Tiagra) STI do.

Traditionally longer chainstays, smaller chainrings, and shorter more curved FD cages on mtb’s made it less of an issue. Plus with the majority being triples, only the middle chainring would hit all the cogs.

Flatbar road shifters present a unique issue because it is possible to have a drop bar bike with trim and the same bike with a flat bar and identical drivetrain not have trim.

There is a simple old skool mod on older FD’s that might give a tiny bit more clearance. If the FD inner and outer cage plates have a screw at the rear to hold them together, you can unscrew it, put a small washer between the plates and screw it back together. It won’t solve it, but it might be enough to help on one cog.

I haven’t had any shifting issues and all my bikes have a washer.
