Proper Derailleur for the old bycicle
I have a Fuji Sunfire hybrid bicycle. Long time ago the original derailleur was damaged and somebody in the bike shop told me to get Deore Derailleur because it is considered to be higher end. At that time I did not realize that the Deore is for another speed count and struggled for years as it did not shift correctly. Finally started to research and found the Acera is the one that fits my bicycle. Got this one, installed and suddenly the bicycle is shifting good, running good and does not make any problems anymore.

schaltet Perfekt
Ich habe die Schaltung in mein E-Bike eingebaut und gegen die alte Acera ersetzt. Einfacher Einbau, Schaltungsseil angeschlossen und Probegefahren. Die Acera mußte nicht eingestellt werden und ließ sich ohne Probleme in alle Gänge schalten. Ich kann die Shimano Acera auf jeden Fall empfehlen. Von mir die volle Punktzahl.

Ideal zum Upgraden von der Einstiegs tourney Schaltung
Habe vom tourney auf Acera rd-m3020 7 Gang upgegradet. Eine absolute Empfehlung. Schaltet die t11-t34 Kassette viel genauer und lässt sich auch besser justieren.
