Kids today have it so good. They’ve got lightweight mountain bikes with high-end tires, fine-tuned suspension, and modern geometry. There’s only one thing they’re missing: a real drivetrain.
That’s where we come in.
Introducing Super Short
Real Mountain Bike Drivetrain for 20" Wheels
We started with the DNA of our ADVENT mountain bike group. Then we made every part smaller and easier to use. Lighter shifting, shorter reach, and more ground clearance, all with the same great chain retention, metal construction, and wide range.
LIGHT SHIFTING THAT'S EASY TO REACH

A REAL MTB DERAILLEUR
Most derailleurs don’t fit 20″ wheels, and the ones that do aren’t meant for real mountain biking.
Super Short has the same clutch and metal construction as our standard ADVENT and Acolyte groups, so the groms can ride as hard as they want without the chain falling off.
PLENTY OF
LOW GEARS


CLIMBING MADE EASY
To work better with small wheels and keep the ground clearance high, we designed Super Short to work with an 11-38T cassette. When you pair that with a 20” wheels, you get a gear low enough to scale mountains.
Gearing feels easier on a smaller wheels. Pairing a 38T cog with a 20″ wheel results in a low gear that feels like a 52T low cog on a 27.5” wheel bike.


NO CUT CORNERS
ADVENT and Acolyte are popular for a reason, so we didn’t remove any features when we made them Super Short.
- Reliable chain retention
- Metric hardware
- Durable metal construction
- Direct cable routing
- Evenly spaced gears
Basically, you can ride the heck out of them and they won’t let you down. No matter how big you are.
IN SHORT
IT'S AWESOME
Isn’t it time for every bike (and every rider) to have a drivetrain that doesn’t suck? Maybe you missed out when you were a kid, but it’s not too late for the next generation. Invest in the future, and check out Super Short wherever cool bike parts are sold.
