Microshift Announces Drivetrain for 20" Wheels

The goal for Super Short was simple: make a real, fully featured mountain bike group for smaller people. It had to be easy to understand and operate, while providing better shifting response and durability than the stuff that normally comes on 20" bikes.
So, we took the DNA of our Advent 1x9 and Acolyte 1x8 groups and rengineered things to be smaller. The result is a drivetrain that delivers big performance for little proportions.
The shifting throw is also shorter than our competitors by over 40%. That doesn’t just help people with small hands – it helps anyone who wants a quicker, easier shift. Even the index-thumb style shifter configuration is a plus: it allows the levers to get closer to the bar and also makes it easier to remember which lever makes it harder and which lever makes it easier.
The rear derailleur is made to be as short as possible. The 100mm cage is about 50mm shorter than standard ADVENT, meaning it will fit on a 20" wheel with plenty of ground clearance for irresponsible cornering.
To play nicely with 20" wheels, we opted for a cassette range of 11-38T. Smaller wheels make gears feel easier; a 20" wheel with a 38T cog feels the same as a 27.5" wheel with a 52T cog. That gives the rider plenty of range to take on anything the rest of the family can climb.
