Tolles Schaltwerk zur angemessenen Preis. Als Ersatzteil für mein neues Fahrrad gekauft und bereits benötigt da das Original Teil nach kurzer Zeit bereits einen Fehler in der Kupplung aufwies. Sicherlich war das ein Produktionsfehler von Shimano. Sowas kann immer mal passieren. Das hier gekauft die Schaltwerk verrichtet nun schon seit mehreren 1000 km seinen Dienst zuverlässig.;

This is is the 8120 2x12 derailer and is not supposed to handle the 51 rear cog. It is exactly tje same as the 8100 1x 12; no difference! It works great on my 1x12, 51 tooth cassette! Less than half the cost!;

Bullet-proof design and flawless manufacturing combine to make this Shimano component a great 'bang for your buck' purchase. This is my second one of these (this one's for my new bike) and the first one I bought has 750 miles of trouble free performance.;

I upgraded my Kona from a 1x10 to a 1x12 drivetrain. The xt derailleur shifts smooth and does well when shifting while on an incline. Highly recommend the upgrade;
