recovery ride. left gps at home. Used phone. Garmin is imported from the Strava TCX export, missing laps and pauses.

Power data is broken, with more drops than connections.
Not sure why, if that’s a Stages BTLE issue, or if my phone couldn’t catch the data from my back pocket.

Also, no HRM data because I only had an ANT+ strap.

My right shoulder is in pain, and very sore from HH100. I had a massage today which helped my legs a bunch, but my shoulder is from a pinch/abrasion in my neck. Low back is sore too. Need more stretching. I haven’t taken NSAIDs yet, because that reduces rebuild based growth/improvements. Maybe tomorrow.

Not sure if I’ll ride Tuesday.

Cycle sensor batteries

Posted by xaminmo

Today, the black-bike started auto-pausing and ate lots of my track. I played with sensor alignment, but realized it was a failing battery.

At home, the multimeter showed 3.065v for that one’s original battery, and 3.05V for the white bike’s once-replaced battery.

I can’t remember when I changed the batteries last. My internet searching indicates that I failed to post about it. In theory, I should get 1.4 years or 500 hours. The best I can tell, I’m getting 400 miles or so.

I replaced them both with fresh, 3.30v CR2032 cells. Unfortunately, these were bulk batteries, and I actually threw several away as being faulty in storage.

I may also need to adjust the wheel magnet, so I can be spaced a little closer, but I’m using monster magnets which trip the sensor from 2″ away.

I thought I might be leaving the magnets such that they intermittently trip the sensor when not in use, but maybe not. The HRM (heart rate monitor) sensor has been replaced, and is down to 3.01v. For good measure, I replaced it with a new 3.31v cell. I think I got 65 hours out of the last one, but it was in the 2.7 volt range when I was losing signal from it. Obviously, it’s much closer to the cycle computer than the speed/cadence sensor.

Anyway, there’s not an easy reminder system for battery replacements, so I’m going to set up a reminder to swap all of the batteries every 5 months.

That’s a little too often, but it’s much better than getting into a ride and having half of the track missing because it keeps auto-pausing.
