So after years and years of riding, it was time to strip it. Now it's down to the handlebars and frame.

The Project.

Buy a used hybrid from Craigs List with 24 speeds or higher (already have another 21, time for a change) and swap everything over.

The Question

Which bikes/models/years can be the perfect donors.

NOTE:
IF I CAN FIND A MODEL WITH 36 SPOKES WITH DOUBLE WALL RIMS, THAT WOULD BE AWESOME.

I need all the suggestions I can get Hybrid Kings...

You don't need to buy a whole bike to swap to 24 speed. Just need new wheels for 8/9/10 speed and cassette and shifter. Unless the other parts are worn out. Are they?

I agree, a whole new bike seems like overkill, unless you already know where you can get an old hybrid for like $25 bucks or something dirt cheap.

IMO, this really seems like a lotta trouble just for one extra gear cog. You could throw a rear wheel from an 8 speed road bike back there and use the same chain and rear tire that you're using now. Your old 7 speed grip shifter might work on 8 speed (sometimes there's an extra "click"). If not, 8 speed grip shifters are like $15 brand new.

I swapped almost everything over from a '97 GT RTS-3 onto a Marin Alpine Trail but there will always be parts you can't swap over, due to variations in sizing.

One i found was the bottom bracket - the GT had a longer tube so it used a 73mm BB over the Marin's 68. Then the steerer tube was barely long enough (i got away with it with no spacers). The seat post was no good, and neither were the cantilever brakes.

As some have said though, it depends what you want to achieve - if you just want to upgrade from 18-speed to 27-speed (or in-between) then all you need is a rear cassette and a shifter.

Not sure why you want 24 speed.
Anyway, all you need is an 8 speed cassette, and an 8 speed shifter to upgrade. Your rear derailleur should have enough adjustment to handle 8 speeds.
Much cheaper than buying a donor bike.
