I find that these brakes adjust easily. Modulation is pretty good, a weaknesses in the mx4 is braking on longer decents tend to bother your fingers a little. These brakes are good if you're getting into disk brakes. Braking power isn't the best but I'm happy. If your bike comes with them they will serve their purpose. But on the upgrade list. I give 'em an 8 out of 10.
