Hi, how do I measure what brake reach I will need for new brakes on a new build?
Do I measure from caliper fixing hole on the frame to wheel rim?

    Reach is the effective length of the arms of a caliper brake. This is measured from the centerline of the center bolt diagonally down to the middle of the brake shoe. Reach is commonly expressed as a range (allowing for the fact that the brake shoes are adjustable, typically 10-15 mm.)
