Let's say the gear shift stick is in 3rd and you wanna downshift to 2nd. Now, you can go:
- pull the lever down to neutral;
- palm left;
- pull down into second.
There's another way though which I usually go for:
- palm left third;
- pull down to 2nd directly.
The same pretty much applies when doing 4th->5th where you'd palm right and push up.
However, I have lately been wondering if this may be of harm (especially when done quickly e.g. on hills or fast downshifts) because, in my humble knowledge, I pictured the selector fork having to follow unusual (forced) paths and thus cause wear and/or issues. Could that be true?
