:exclamation: Hint: Crank extractor tool required for beltwheel set installation!

Looks like only the last one has belt guard on the inner side.

Btw, do they make rear freewheels for strida?

On the first type the belt guard is realized via one “guard tooth” per tooth of the wheel on the inner side.
(Please refer to pic 7)

I’ll ask for it…
Guess your wish is a steel freewheel?

Thank you, I’ve overlooked that. Such guard teeth might be good in helping preventing belt twisting…

Thank you.

Or at least an aluminium one with hard anodizing.
