The S1000 Eagle Transmission derailleur is your wireless entry point to the Eagle Transmission ecosystem. Utilizing the same striking architecture as our GX Eagle Transmission derailleur, the Full Mount design mounts around the wheel axle itself with no hanger required, bringing strength and durability to any bike. Cassette Mapping, a marriage of the derailleur’s firmware with the hardware of our T-Type cassettes, helps deliver the best shift under load, even under the added power of an e-mtb. And like all Eagle Transmission derailleurs, it’s rebuildable, with replaceable skid plates and two-piece outer link, and a removeable cage assembly that simply rotates off. Featuring a sleek black on black appearance, this derailleur can be mixed and matched with all other T-Type ecosystem components for total customization of your bike. The S-1000 Eagle Transmission derailleur also features our new Drag Spring Cage Damper for reliable chain retention and long-term durability.
