I have not used Miche 11 speed, but have used numerous 9 and 10 speed cassettes. They always shift fine and seem to be durable. The ones I have used all had individually mounted cogs, which makes it easy to customize. If I needed and 11 speed cassette, I would not hesitate to purchase a Miche. I just ordered another 9 and 10 speed Miche cassette to have on hand.
