I have an old hand-me-down Roadmaster (I know...) MTB that I'm trying to keep running for a while longer. It's a 3x6, with front and rear derailleurs both branded TD-One, a TD-One twist shifter for the front and a SRAM Quick Shift twist shifter for the back.


The rear shifter-derailleur combo work surprisingly well.


In the front, the shifter needs to be replaced, and at the same time I would prefer to switch to a trigger shifter.


In a local community cycle shop I found a used Shimano Deore XT SL-M770 3 speed front shifter for a really good price. I've read that TD-One derailleurs are "compatible with Shimano". Would this combination work? Thank you for any info.
