Discussion of This Ride’s Results
We decided to do a short ride after dinner as we were both recovering from the Wausau 24Hr Endurance Mountain Bike Race from the previous weekend. Using Cykelstrom during that race taught me a few things about my racing. To see the video and read about the race please visit Cykelstrom Mountain Bike Power Meter App Test Ride – Wausau 24.
Back to this ride’s results, we can see that out of all of the combinations of using external sensor to not using any external sensors that the worst case scenario is within 14% of the standard power meter for this ride. The best case scenario was within 5% of the standard power meter. The surface of the road was fairly smooth. The mountain bike used was a Trek Top Fuel 8 with the suspension locked. With the suspension locked there was still some movement of the suspension so it was not like riding a hard tail or road bike. I believe the results of this ride reflect the moving suspension.
