You don't "ADJUST" spokes on a properly spokes wheel.
You'll reduce tension which lets the wheel go out of true.
Trying to compensate for that and you end up with a wheel with unbalanced spoke tensions and wanting to go out of true every time it takes a knock.

IF your spoke is too long, grind off the protruding part with a Dremel tool or similar.
Your spokes should all have the same protrusion per side. If they vary, somebody probably tried a ham handed truing job without seeing "the big picture".

Use your search engine for single wall & double wall rims.
IF yours are double wall, your spoke would probably run out of threads before it could protrude.

I once ran into an old tube that had tiny specks of what could basically be described as "carbon".
I'd patch a hole and when inflating, it'd produce another hole or 2 near the patch. After 4-5 patches, I tossed the tube for a new one.


You said the bike sat for 2 years, but how old is the tube?
