Less than two months after launching their cable-actuated Eagle 90 and Eagle 70 drivetrains, SRAM has rolled out an upgrade kit for riders that want to convert a cable-actuated Transmission derailleur to a wireless one. The kit comes with a wireless derailleur body, a wireless shifter, battery, charger, and PowerLock quick link. The kit uses an existing Transmission 90 or 70 derailleur’s lower cage and mounting bolt – it’s the body of the derailleur that gets swapped out for a battery-operated one.
Installation should be a fairly quick procedure, and it’s something most riders with a bit of mechanical know-how will be able to accomplish at home. Realistically, taking the old shifter, cable, and housing off a bike will probably take longer than converting the derailleur. “Old” probably isn’t the most accurate word in this case, though, since Eagle 90 and 70 drivetrains have existed in the wild for a fairly short amount of time.
It is important to note that it does not include the pulley cage or mounting screw, elements that must be reused from the previous derailleur.

While the $550 price tag of this kit is $126 less than you’d pay for all of the parts individually, it’s also roughly the same price as a brand new Eagle 90 cable actuated derailleur, cassette, chain, and chainring. At the end of the day, it all depends on weather you want to
