GX DH 7 speed rear derailleur

We understand that knotty line requires a lot more focus than a supermarket tour. That's why we've packed the GX DH 1x X-HORIZON™ rear derailleur with world championship-winning features and priced it more in line with the Wednesday night championships. This is a DH derailleur that's easier to shift, incredibly precise, and keeps unwanted chain slap noise to a minimum, so you can focus on the smooth feeling of nailing your line. GX DH - Get some.
