Durable smooth derailleur.

Shifts smooth even under load on uphill climbs and durable. Mine has taken some hits, but still functions perfectly.

ENSOR XT SHIMANO

PERFECTO EL ENVIO LLEGA EN SU CAJA ORIGNAL MUY PUNTUAL. DE LOS MEJORES TENSORES EN EL MERCADO. SUAVE ESTABLE. PRECISO. ESTOY PROBANDO CON UNA PACHA NX DE SRAM Y UN SHIFTER OPALANCA DE SRAM GX VA BIEN AL MOMENTO. NO LA HE PROBADO EN MONTAÑA COMO DEBE SER PERO AL MMOENTO SE DEJE CONFIGURAR PARA HACER LOS CAMBIOS FLUIDOS EXACTOS Y SIN RETRASOS. SI HAY ALGO DE ERROR LA ESTARIA CAMBIANDO POR LA PALANCA XT.

Strong, precise and reliable

Shimano's quality on this XT derailleur is simply excellent. Very precise, smooth and strong...I'd say that it takes much more abuse than the XTR ones. the only thing is that you have to do some maintenance on the clutch, make sure to clean it once in a while and put some waterproof grease on it (Check out for the instructions on Youtube).

Great drivetrain, plan ahead, finicky

I updated from SLX 11-speed to XT 12-speed. When it's dialed in, it's fantastic: fast and crisp shifts, great gearing on the 10-45. But it's finicky. Make sure to follow setup instructions carefully. Chain length, b-screw adjustment, hanger alignment, and cable adjustment are very important. Maybe it's just cable stretch and break-in, but so far it requires way more adjusting than my previous 11-speed setup on the same bike.

Xt, nice extras over slx

The Shimano derailleur is easy to set up and this one is too. Nice having bearings instead of bushing in the jockey wheels and an external clutch adjustment is nice. Flawless out of the box, highly recommend.
