Question: On my r700 w/ the shimano r550 wheels, there is bearly enough space to mount the sensor on the inside of the fork which is heavily profiled to match the profile of the tire and wheel, (there is not enough clearance between the spoke and sensor) so how far to the front or the back can the sensor point before loosing effectiveness? Mine is about 2/3 the way up my fork and I would like to mount it closer to the hub but am worried about the sensors position.
