THE HG400 MODEL IS REPLACING THE HG61
12 - 14 - 16 - 18 - 21 - 24 - 28 - 32 - 36 Teeth
Note: Shimano recommends that this cassette is only compatible with Shimano Shadow type rear derailleurs. We've run it successfully with a basic Deore (non-shadow design) with a longer (20mm) B-tension screw all the way in. You might have to reverse it for more adjustment.
If this cassette is being used on a 29er Mountain bike, it must be used in conjunction with the Shimano M629/M529 29er hubs.
Designed for 29ers but is also a new option for touring bikes!
No need to replace your double crankset when you have a 36t bailout gear!
This cassette will fit any Shimano 9-speed hub.
