I do not have the rear brake, I do however own a pair of alternate GB brakes, but condition is not as good.
As i said in the listing the rear hub is flip flop so one side is currently fixed gear, the othe side is unassigned and can either have another fixed gear on it or a single speed cog, I also have one of these that I have not attached yet.
I will need to measure rear drop out tomorrow, as the bicycle is currently in my workshop.
wheels are 700cc, hubs are made by airlite
