OK so I have a strange observation and I wonder if anyone else has experienced something similar. The group I ride with do weekday rides following the exact same route every time. I recently upgraded from a 26 inch bike to a 29 inch bike and my ride distance, measured by a Garmin Edge 820, changed from 15.13km to 14.94km. That's 190m less and is a 1.3% difference.
Now I thought it was a new downhill section that may be shorter, but looking at the map, both rides I'm comparing used the same route! Could it be possible for a Garmin mounted on the handlebars to measure a difference in how I track through corners on these new bigger wheels and could it be that big a difference? It seems so crazy yet I can't (yet?) see another explanation??
So, am I crazy or what?
