Your cart is empty.We've all been there, grinding slowly up a never-ending climb as our cadence slows to a high-torque, barely moving crawl, fruitlessly clicking the shift lever in hopes that an ethereal body will drop out of the sky and deliver an extra cog to lighten the pressure. All jokes aside, SRAM swoops in with its top-spec XX1 Eagle 12-Speed Rear Derailleur. It's situated as the lightest mechanical rear derailleur in the line, and utilizes top-tier materials for an impressive strength to weight ratio. The titanium spring and carbon fiber outer cage deliver precise gear changing across the entire cassette. The Roller Bearing Clutch, long revered for its nearly unbeatable chain stabilization, gets an update with a repositioned upper pulley and larger lower pulley to accommodate the extra chain length needed to run such a wide range of cogs. With SRAM's Exact Actuation technology, each gear shift requires the same amount of cable pull, resulting in a predictable click and shift no matter where the chain sits in the cassette. SRAM's nifty lock pin design also makes it easy to lock the derailleur in place with the chain slacked out to make it easier to pop your rear wheel on and off.

I bought this as a replacement for a circa 2016 version of the same product. The installation and tuning was smooth and reliable. I've been using it about 6 months in harsh conditions and the performance is on par with the original. Good product.

Amazing amazing 6 stars out of 5...I have used electronic shifters and this is almost as smooth when it comes to switching gears on the trail. An absolute must buy and the gold adds some solid (but not over the top) bling to your bike. So happy its like a have a new bike after upgrading from sram sx.

Recibo el paquete y la caja es de xx1 eagle negro 12 v y me mandan un eagle gx...lo he devuelto en cuanto lo he abierto, menuda decepción. Y el tornillo que sujeta el cambio a la patilla tiene el contorno algo rayado y ha perdido parte de la pintira original negra.

I cannot say enough about this 12 speed system. I love it. I have used many different mtb configurations in the past 3 x 10, 2 x 10, 1 x 10, 1 x 11, single speed and I love the simplicity of having just the rear derailleur and this derailleur shifts so nice and quick and gives me a great range for going fast on the flats and spin up the steep climbs.

Inner cage (forged aluminum) bent when rear wheel spoke broke. Replaced cage and all works as designed.
