1x drivetrains on mountain bikes just make sense. There's just too much gearing overlap on a 3x and 2x drivetrain and you simplify and lighten up. The Microshift Advent stuff is a solid bit of kit. I have the Advent 9 and 10 speed stuff on my bikes. Cheap on the wallet and the gearing range I could ever want. I bought them from Universal as well and got it within a week from the PA warehouse.
