Confused by shifters

Hi Folks...

I normally ride roadies but I recently got the idea to fix up my old Trek 820 to do some trail riding...

First thing I noticed was the grip shifter for the front was broken. Probably brittle from age...

I'd rather use trigger shifters but I'm a little confused as to what will work with my current drive train...

Right now on the back it's a shimano Acera X rear derailer and an SIS front derailer - triple and 7 speeds in back

The shifter were gripshifts 3x7 but as I said, they are in sorry shape.

I've used the trigger shifters before (Deore) and I liked it and I guess I would like to upgrade this bike to that...

so the questions are:

Given my drivetrain what trigger shifters do I need to buy? I want the shifters only, not an integrated brake/shifter pod. I don't want to mess with the brakes.

Also, if I decide to stay with grip shifts, what will work? Will the Sram stuff work with my gear?

I guess I'm just worried about the shifters (either style) having the correct spacing for my drivetrain.

I'm not looking to spend very much money at all on this.

Would something like this work?

thanks very much for any help

I'm with you on the trigger shifters; I don't like the twist type.

A few things:

The SIS on your front derailluer just means it is a Shimano derailleur (SIS being Shimano Indexing System so releavnt to any shimano component designed to be used with indexed shifters); since rear is Acera, best guess is that so is the front (although not necessarily).

Pretty much any shimano-compatible indexed shifters will work. 3 speed front and 7-speed rear shifters are widely available in both trigger and grip and SRAM shifters should work. The ones you linked to will work but since you say you want shifter only, this SRAM one or the Alivio you linked to would do.

Bikes: I never learned to ride a bike. It is my deepest shame.

The second one you linked are nice shifters and will last years and years.

Your old gripshifts cracked, not because they were old, but because they were crapola. I would guess that between a third and a half of all gripshifts sold on entry level bikes broke in some way. Crap-Ola.
