Before you buy anything,make sure the shifter is adjusted corectly. Put the bike on a stand or whatever it takes to allow the pedals and the rear wheel to move freely. The adjustment should be made from the second highest gear (the second smallest Which is the second from the outside). Tighten the adjuster until the chain makes noise trying to shift into the ...

A couple of things could be the reason of your derailleur shifting on its own. I assume that both the derailleurs and the shifters are in good working order, that you washed and lubricated them and correct adjust them with the respective screws. Please refer to Park Tools repair help guide to correctly set all these adjustments. You can find it here and ...

If you take this bicycle to an LBS asking them to fix this, chances are they will try spraying the guts of the shifter(s) through every opening using something like WD-40. Since WD-40 gums up after it dries, I'm not sure I'd use that; maybe this video will be helpful. You can also try lubing the cables by squirting lube into the end(s) of the housing. I ...

Ghost shifting is generally caused by the frame flexing, not by friction in the cables. Other causes can be a poorly fitting or too short cable housing. Something is causing the length of the cable between the stops to change. Cleaning the cable run and using a teflon coated shift cable won't hurt and might alleviate the problem if it's a combo of bottom ...

SO I recommend working on your Secondary Problem first! :-) NOTE: Allow plenty of time for fiddling with your gears. Do it in a warm dry place when you have time so you can learn how ...

You probably have the right drop out width. Unless it has down tube shifters you have cable routing. The chain size must match (e.g. cassette number of gears) and chain ring width. Your existing chain rings are probably too wide. But I think you would be better off finding a newer used bike with the stuff you want. If you stay with the same number of gears ...

Thanks for posting this problem. I have exactly the same with my Cannondale Synapse alloy 2009 (Tiagra triple). During every ride I have to tighten the micro-adjuster. After renewing cables, housings, bottom bracket guide etc several times I have finally reached the conclusion it's the barrel adjuster itself.
