You’ve started a 1x10 build with a big ol’ range on your rear cassette. Now you’re looking for a simple, beefy rear derailleur. Opt for the Shimano ZEE RD-M640 Shadow+ 10-Speed Rear Derailleur. With it's low profile design, the RD-M640 slides in below the cassette, and can handle up to a 36t cog in the Freeride option (28t for the DH option). Fight chain slap and rule the downhills.
Shimano Shadow Plus Technology – Proven to reduce chain slap, drop and impact noise.
