The measurement offset is a measurer’s good friend. Sometimes it is necessary to ride a course with traffic instead of against. Of course we all use offsets to maneuver around parked cars. Yet, an offset to move the bike across the road, while freezing the front wheel, is really very helpful to avoid those heavier and unsafe traffic situations. The measured distance is always the same, but without the fear of oncoming traffic. Have found that too many offsets are a little tricky when using Neville’s cyclocomputer measuring.
