Re: Which side of the fork does the Sturmey Archer XFD brake arm go?
I generally orient the wheel to where the cable and lever are in front of the fork. Members have told me that I can reverse the wheel if it provides more braking power.
Experiment to see if the brake is more powerful in one direction over the other. If braking power is the same, mount it however it fits best.
