in fact in the last 35 years of working on 100’s of bikes that’s the only time ive ever needed one.
The opposite happened with me 🙂
Just because I could,once I had the tool,I ended up checking all my frames( and the frames of club mates).
Most weren’t that much out,but some frames(PX) had a hangers made out of cheese.
It felt at times like a hard stare could knock them out.
Any shifting issues I now get,it’s nice to be able to quickly check the hangers.
@nickingsley I took the barrel apart and had access to a selection of steel shim to make it a tighter fit.
I know that the sloppy movement over the lever distance ,was not the end of the world, but it just bugged me that far away in some Asian manufacturing empire,they couldn’t be arsed using better fit/tolerances 😉
