Ratings & Reviews
Quality fit and finish.

Fit and finish means it truly is an easy bolt togther change with no fuss. Slightly taper-shouldered screws also mean it's pretty much self aligning. I fitted this in a 30T (changing from 32T) to try and get better climb performance out of a 11-42 11-speed XT M8000 cassette on a 29er hardtail. While the climb gears do become easier - it's worth noting that the gear increments feel a lot larger when changing gears in the mid-range and drive gears. Consider the 11-46 cassette instead if looking to resolve a similar issue.
