The Shimano Alivio RD-M3100-SGS rear derailleur is perfect for 2x9- as well as 3x9-speed MTB riding. Its low profile Shadow RD design avoids not only damage from rocks, but also improves shifting performance. The Top Normal rear derailleur accepts cassettes with a maximum range of 11 to 36 teeth. The guide and tension pulley of the long SGS cage feature 11 teeth each.
With their sophisticated technology, Shimano Shadow RD rear derailleurs are especially intended for more aggressive riding style. Their super low profile design carries many benefits. Thanks to the low profile and a single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
