These adapter brackets are designed to work with the Post Mount style brake mounts. Use the variant selectors to find the right bracket for your application.
Works perfectly so no spacers are needed for the 203mm rotors!

Post Mount Adapter
Exactly what was needed to mount my Dominion A4 brakes on my bike.

Post mount adapter
Nice package, works well. Necessary hardware included. Aesthetics could use some work, but at the end of the day it’s just an adapter.

Only way to go for fitting these giant calipers. Looks nice was well packaged with all the needed hardware.

Quick and Effortless
The new A4 Calipers are a chonky meatball of phenominal cosmic stopping power. As such they wont mate with standard Shimano brake adaptors. Pick one of these up so you can run your big fatty 223 rotor on your Zeb and save yourself 15 mins staring at your hands wondering if its you and not the shimano adaptor thats the problem.
