Nice pics:)
I want to put on a break as well but Maguras are too pricey for me:(, so I’d like to get one like yours.
Did you just mount that break into one of the Magura mounts or did you have to use an adapter (if so where did you get it)?
What is the make and model of that break (since some have more, some less clearance)? What’s the max tire you can run w/ that setup?
But I noticed them first
