Front/Back Motion and Slosh

This is a silly nerdy question... I run two tall bottles on my frame. I have the impression that it might make a Tilt difference in how I drink bottles empty. On rides where I drink first the front bottle and then the back bottle (I don't switch front to back when empty), my Analysis Tilt Chart seem...

Low battery on the Garmin gsc-10 will show cadence but no speed. Battery can fail overnight if left with the magnets over the gsc-10 sensors.

Re: Scan for sensors

As long as you make sure to tighten your Newton on to your mount, water won't leak into the USB port (we've tested this!). So, I would not worry about replacing the cover; you can rip it off if you wish. I have an intact USB port cover (which can be hard to open with short finger nails). Today's ri...

Re: Cadence data sent out under the umbrella of GT key?

No. GT enables iBike power sending information. It has nothing to do with cadence. I disagree! I have had a low-voltage gsc-10 which would detect cadence but not speed. This is a known result of gsc-10 low battery where the gsc-10 will continue to report cadence but fail on speed. I set my Edge 500...

IF you happen to see a big change post analysis for whatever reason then you would want the iBike data. That said, it's not like you're using Strava for detailed analysis so the FIT file sh...

This has to do with how much time passes between when the cyclist stops pedaling and when the elapsed time counters stop accumulating. Apparently, the Garmin is different from us.

With the latest firmware (4.0) and Isaac (2.1.0) loaded for today's short 13 mile O&B ride, there is still a variance between what Newton reports and the reporting by Isaac and Garmin Edge for average speed (0.1 mph less on the Newton).

On import from Newton, Isaac 1.0.10 now scrolls the lap window (left lower pane) so Lap data is not displayed.
Seems like it does a Page Down/End. To correct it and see laps, you have to scroll the window to top.
