is this for a 7300 FX ?

not familiar with this bike - but familiar with similar bike (FX 7.3 with a triple) ...

if your current shifters / shifting is fine - I would be hesitant to change from a triple to a double ... not sure how much is to be gained in this particular application ... ? ...

you could possibly convert to a poor man's double ... ? ... remove the small ring - adjust / block the derailleur from moving to the small ring ? ... again - I don't know how much is to be gained in this particular application
