Instead, power is delivered through a metal cable that tensions as you squeeze the brake lever - similar to how many motorcycle clutches work.

Use the Right Screwdriver For the Right Screw Type!
What happens if the screw gets rounded down?
Each screw head has one or several edges designed for the corresponding screwdriver.
If you round these edges down, you’ll damage them – so much that you won’t be able to remove the screw.
It doesn’t matter if you switch to the correct type of screwdriver afterwards – once you round down these edges, it’s more or less irreversible.
Bottom line – just like you must use a correctly sized spanner or socket for a socket wrench, you must also use the correct screwdriver for the job.
