Lock the crank to lube chain - tool

[Stefan Mikes]

@fooferdoggie suggested it so i got it I guess it's standardized for most e bikes.
I use it once a month to check tourqe specs on my drivetrain and suspension.
Mainly on chain ring bolts and brake components rotors calipers etc.

How odd... do they unscrew themselves?

I only use the torque wrench to tighten components to the spec when they are being installed on the bike.

Nothing wrong with that. Especially with the safety check.

No they don't and not supposed to.
It's good habit to check
for peace of mind..

yep. They’re not supposed to.

until they do - usually due to vibration over time.

never hurts to check torque on critical stuff
