We noticed excessive wear on the downward-facing sections of our own chainrings during descents. The chain drops off the bottom of the chainring, slaps back up, and chips away at the teeth. This causes unnecessary noise and accelerates component wear.
Now you can download the file and print your own Side Quest Under Guide that plugs directly into a OneUp Bash Guide. When printed in a flexible material, it keeps your chain aligned, reduces drivetrain noise, and extends the lifespan of expensive components.
