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!
