Is there much difference between Altus & Tourney?

So my front mech seems like it no longer wants to play. Regardless of the adjustments from tutorial videos I've seen it will not change gear. I've raised the mech, lowered it, pushed it to the side more, tightened cables etc and no joy. The only thing it will do depending of the position is push the chain onto the 2nd cog (triple front). I'm thinking to just replace the lot with a Tourney or Altus but in not sure if it's going to make any difference with either seeing as it's a Falcon system which I believe is very similar to the Tourney I performance.

A Tourney will be a definite upgrade vs Falcon.

Are you sure it's not the shifter?

If there's a frayed cable or kinked cable housing, then adjusting the DR won't help at all.

As far as Tourney vs Altus, it's more a feature thing. Altus can get you 9 speeds on the back though if you want that. Not certain, but between the Tourney shifter's and Altus shifters, one might be hold up better when ridden in really dirty riding conditions. But someone that mountain bikes will have to chime in on that.

Check to be sure the cable is routed correctly and clamped correctly. Makes a difference in shifting, front and rear. The clamp bolts will have a notch that tips us to how the cable should be run and clamped.

If your bike has Shimano RevoShift grip shifters, that's the next thing to check. They're all plastic except for a couple of springs, so the detents that hold the indexing will wear or break within a few years. Not repairable. A replacement set costs about $10-$15. Should include an entry level set of galvanized cables and cable housing to fit a typical hybrid.

Or get the SunRace SLM10 friction thumb shifters for the same money. They'll last for years. Various entry level trigger shifters will cost a little more, maybe $25-$35.

Altus derailleurs are fine. I have a set on my Globe Carmel errand bike. Cheap and functional. Durable too -- I've crashed on the right side a couple of times, no damage to the rear derailleur.

Trying random adjustments or parts swapping is inefficient. I would suggest removing the shift wire from the derailleur and checking, while applying tension by hand, to be certain that the shifter actually pays out and pulls in the wire when commanded. Then check to be certain that the derailleur cam be moved by hand while turning the crank; watch your fingers. Then adjust the derailleur in accordance with this procedure, not skipping any steps: https://www.parktool.com/blog/repair...eur-adjustment
