Hello there! Congratulations on your purchase of the All-City Master Dropout, a sliding dropout system
consisting of replaceable dropout plates and fixing hardware.
With precise engineering and lasting quality baked into its DNA, the Master Dropout is not designed to be
disposable. Meant for use only with compatible All-City models, this support piece allows you to quickly switch
between a geared or single-speed setup without requiring additional chain tension adjustments. This makes it
possible to use a single frame for two equally excellent cycling experiences.
Once installation is complete, consider sending some photos of your stellar bike to info@allcitycycles.com.
From all of us at All-City Cycles, cheers!

Overview:
The Master Dropout allows the Super Professional to be setup as geared or single speed. There is a separate
slider for each configuration. The geared configuration has a threaded derailleur hanger, and the single-speed
configuration has no derailleur accommodation. The rest of the hardware is the same, however, whether the
setup is geared or single speed, and both configurations are designed to accommodate a 12x1.5mm thru-axle
and flat-mount disc brake.
