GT85 for stuck trigger shifters?

norakay

Hi. One of my trigger shifters is stuck. The advice I got online suggests first using a solvent to free up the shifter and then a lubricant.

What I'm wondering is if I can use only GT85 for this. I know it's a lubricant, but is it also a solvent?

Thanks for any advice.

cheers,
Nora

I would be opening them up and seeing what the problem is.

As if it is stuck I would guess it is something a bit more serious.

GT85 is the answer no matter what the question is.

As nicklouse said, open it up. It's only (usually) 3 screws or so.

I reckon you're more likely to find it's not the shifter that's stuck, and once you remove the cable it'll work fine.

I used WD40 for that exact purpose on a friends bike that had been stuck in a shed for years. Before starting there was zero movement in the shifter. Post application (and a lot of wiggling) they got full movement back.

When you say "stuck" do you mean won't move, or won't select a gear properly.
If the latter, I had similar problems. It was the ratchet which had stuck because the grease had hardened.
I took the cover off the bottom of the shifter (no springs under this bit) and freed it off with GT85. A drop of light oil and all was - and still is - well.
If it's the former, the other posts have covered this. Could it be that your cable has rusted up big time?
Good luck!

Yup GT will do the job and smells nicer than WD. Allow to dry then pop some oil or spray grease in there.

Also check, as above, the cable and give a once over to see if there is any other gunk in there that may be causing the issue.
