'Some more feedback from the Aggregate 100 in North Yorkshire. The Rad8s again performed admirably. The course is 100km with about 1700m of climbing, so a grand day out (grommit). Vision was again much improved over contact lenses, one highlight being the first off road descent. This is steep, rocky and with many small drop offs. Normally vision on this sort of riding would be very bad, it is almost as if my contacts bounce about, remember I'm on a cross bike. With the Rad8s my vision remained sharp, allowing me to pick better lines and increase my speed. That my brakes weren't coping is another matter😀' Peter
