Brake Lever Right 8-Speed Microshift

I've lot the count of the amount of time I've spend trying to re-index my gears and asking myself why the hell the chain was going down 4-5 cogs with a single shifter click. By the time I opened the shifter lever to see its internals I finally noticed the spring/cog system completely opens and jumps multiple steps with a click. So it is faulty. Then I come here to try to replace it and find that: 1) There are plenty of reviewers that ended here after having the same issue. 2) Microshift has some sort of global shortage and this lever is not available on Decathlon or anywhere else, making the replacement impossible. The only good thing is that is Shimano compatible, and that MicroNew versions are available from China. So here I am, buying a chinese knockoff because I cannot even buy this piece again, even when knowing it is faulty. Why does Decathlon keeps using this faulty shifter?

Bon remplacement du levier sur mon vélo, assez rapide.

Marche très bien
