75mi Grand Prairie Ride

Meet-up at Cadence for the weekly long ride. Attendees included:
Theresa (invisible), Steve, Kathy, Amanda, Sharon, Becky, Karl, Jim, Josh (Me), Mike.

We rode down across the Grapevine Dam, through the airport, looped around the Grand Prairie race track, then up through Irving (including Las Colinas and Valley Ranch), and stopped for lunch at Hard 8 in Coppell.

On the way through Valley Ranch, Mike bonked pretty hard, and we were worried he wouldn’t make it to lunch. He’d been off the bike for a few weeks, a little short on sleep, etc. However, after a Cliff Bar, he magically came back to life. Tired, but powered through just fine.

Amanda had an indexing issue on the rear derailleur. At first we thought maybe a bent hanger, or bent RD, but on closer inspection it looked okay, and the chain seemed straight. 2 twists of the inline barrel mostly fixed it. It probably needs a little more, or maybe just zero out the cable and re-clamp it. She was tuckered out and sagged back to a bike shop for adjustments.

Karl dropped the chain off the inside of the cassette. No spoke damage, and easy fix. He stopped pedaling really quickly, so it didn’t wedge in behind the cassette. KARL! REMEMBER TO ADJUST YOUR LOW LIMIT STOP SCREW!

At a couple of pauses, I had to check email for work, but things went pretty well. My shoulders are sore. My hands are sore. Need new gloves, because I buy cheap, and my right hand is getting a blister. I remembered to go fairly salty on my beverages and food. Need to remember more tonight, so I don’t cramp up on the airplane ride tomorrow night.

After lunch, we took Freeport/Lakeside/Garden Ridge, and then the Flower Mound trails up, came down Briarhill, and back through to Cadence. From my house to the second Cadence stop was exactly 73 miles, so the actual loop was 70.85 miles. Wheel calibration should be within 1%. Some of the others rode from further, so they had as much as +9.

Lots of good conversation, rambles, and not enough sprinkles. The humidity, and the wind from the south was pretty brutal, but we survived. Overall, it was a great ride.

Watts are complete guesses. If Calories are correct (FirstBeat/Garmin), then I averaged 195W. If Strava is correct, then 145W. If my calculator is correct, then 551. Nothing really factored in wind. So ready to have a wattmeter.

I checked on my Easton wheels, and they do have a squeak/problem. It’s been 3 weeks, so I’m a little antsy. The plan is to ship them off late next week, and will probably get a factory replacement. I said I’d follow up in a couple of weeks. Wattmeter ordered 2014-06-09, so that would be the same time I would check to see if it’s in (3-6 weeks).

Sat Krum Ride Plans

Riding HV, Argyle, Ponder, Krum, Denton, HV tomorrow morning. Water stops in Ponder and Krum. Food stop at Cartwright’s Ranch House.

I’m not certain about riders and winds, but I’m expecting to average 16mph on the way up, and 13.5mph on the way down.

I guess I should re-connect my front derailleur. :)

Cycle sensor batteries

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.

2013-10-30 Bike Cadence

Just putt-putting around with Mark. We visited Cadence Cyclery. Broke my headlight, and even so, it was vastly inferior. Some lag in GPS waking up both times.

Strava would not read this file off of my Garmin. It says “Error” for status. I had to export from Garmin then upload this file.
