Camera damage in handlebar-mounted phones?

[Stefan Mikes]

How do I get rid of that green GPS staus tab blocking my bottom 2 (clock and battery) data fields? I think it stayed there during yesterday's test ride.

It will disappear as soon as you press the Start button.

Please detect HRM from the ACE device. Disconnect the Specialized App connection (forget sensor there). Bluetooth usually can serve one channel only.

Thanks! Correct.

My cheap HRM may be at fault here. Connections to the Specialized app were getting intermittent pre-ACE, even with a new battery and cleaned electrodes. The Wahoo app pairs with it (after unpairing with the Specialized app) but can't hold a steady connection.

Guess it's time for a new HRM. Any advantage to the Wahoo HRM?

It's a little big for an implant...

Morning, Jeremy!

I think I know how you can determine your true FTP! As you know, Wahoo app synchronizes with ELEMNT post ride. Please watch your completed ride in the App carefully. There is a Power Curve chart. Just have a look at your leg power after 1 hour: that is what you can use as your FTP. It is the most depressing in my case as my bad legs can produce just 60-70 W!

Sometimes, the Wahoo Cloud experiences a hiccup. In such case, you'd get your ride synchronised only after several hours (it has happened to me twice). Eventually, all will be sorted (the older app/device didn't depend on the Wahoo Cloud).

Guess it's time for a new HRM. Any advantage to the Wahoo HRM?

I have used a Polar OH1+. It is one of very few reliable HRMs that takes a form of a wristwatch and provides the data online (ANT+). However, I haven't used it with the ACE as I don't need an HRM. I can test it for you today (I meet Tommy on a group ride and he's wearing my Polar). Now, I know nothing about the Wahoo HRM.

Thanks! It'll be interesting to see how that FTP estimate compares with the 2x8-minute test result of 185W I'm using now. Given the great variation in my rider power over a typical ride, and the near-zero chance that I'd ride an hour without stopping, hard to see a credible estimate coming from your method.

What's the evidence for it? The 2x8-minute FTP test can't give more than ballpark estimates but some online coaches find uses for it.

CTS Field Test: Why Two 8-Minute Efforts Are Better Than A 20-Minute or 60-Minute Time Trial? - CTS

Some athletes and coaches ask me about the rationale behind the two 8-minute efforts that make up the CTS Field Test. My field test is unique in its brevity; it’s not a 60-minute or even a 20-minute time trial because I’ve found that I don’t need to put athletes through such an effort to gather...

Realistically, it's the best of the shortcut tests that I can actually perform outdoors from home.

Sticking with a chest strap, so dithering between the Polar H10 and the Wahoo Trackr.

Similar cost. Both can hold 2 or more Bluetooth connections at once. Cyclingnews and similar online reviews give both high marks, but both get spotty Amazon reviews — especially on reliability and longevity.

 

[Stefan Mikes]

I know very little about the cycling performance. Just looked at the result of my friend Marek S (age 54) who works hard on a cycling trainer under the supervision of a coach. His latest 1 h 18 min indoor ride gave the average power of 172 W. His average power on a real group ride he lead gave his average power of only 130 W. I think 185 W is a lot...

I respect your choice of a chest strap HRM. Just want to tell you my friend Tommy used my Polar OH1+ on both Garmin 540 and Wahoo Roam 2 yesterday on two separate rides and it worked nicely. The OH1+ was also detected by my Wahoo ACE as an ANT+ device.

 

[Jeremy McCreary]

I think 185 W is a lot...

I also think it sounds high, but that's 90% of the better of the 8-minute averages from the SL's built-in power meter. At my weight, that comes out to a semi-plausible 2.1W/kg.

@mschwett , who's had a lot of power meter experience, once said that his Specialized built-in power meters tended to run a little high. I think he said by 5-10%.

Taking the more pessimistic 10%, that'd drop my 2x8-minute FTP to a more plausible 168 W or 1.9 W/kg.

 

[Stefan Mikes]

Jeremy, I'm still thinking... Wahoo doesn't by default include zeroes in the stats, and the Auto-Pause is reliable. If your rides extend past one hour net, the Power Curve should give your 1-hour power (FTP). If that figure is lower than you thought, you might still accept is as your FTP.

The reason I think so is I looked at the performance of strong riders I know well. Jacek rode as a "horse" on a group ride yesterday, and his power was estimated to just 158 W... I wonder if you could ride gravel for at least 1 hour (net) at an average speed (net) of 15 mph unassisted?

 

[Jeremy McCreary]

I wonder if you could ride gravel for at least 1 hour (net) at an average speed (net) of 15 mph unassisted?

Absolutely not. But none of the FTP methodologies you mentioned strikes me as more reliable than a recognized FTP test that I performed as directed with my SL's power meter.

You should read up on the metabolic meaning of FTP and the nuances of measuring it. None of the many sources I read would measure it as your're recommending.

Thanks! Correct.

I've had both Garmin and a Wahoo Tickr chest strap HRM's. All the Garmins died eventually. To be fair, they were used year round for training and racing by someone who sweats profusely. The Tickr has been working just fine since I bought it about 10 years ago. It's been through about a dozen batteries. It transmits both BTLE and ANT+. The chest strap isn't as good as the Garmin strap, so when that died, I replaced it with a Garmin strap. It's been fine ever since. I highly recommend it.

Very helpful! Any thoughts on my other contender, the Polar H10?

 

[stompandgo]

Polar has been in the HRM business longer than both of them, as far as I know. I don't like wrist sensors at all.

 

[Stefan Mikes]

Jeremy, did you turn the sound off on your ACE? Why?

I've found it useful to listen to the voice navigation. No need to stare at the screen for most of the ride!

 

[Jeremy McCreary]

Jeremy, did you turn the sound off on your ACE? Why?

I've found it useful to listen to the voice navigation. No need to stare at the screen for most of the ride!

I ride from the house 98% of the time. No need or desire for turn by turn navigation on most of these local rides. And I certainly don't want to get beeped with silly notifications about things like climbs ahead.

Also keep the nav voice off in the car. No desire to listen to all that kibbitzing for the few turns where it might actually be useful.

For one thing, I seldom ride pre-planned routes beyond the first target, which is often still TBD when I leave the driveway. Generally follow my nose from the first target. This usually results in longer rides and more climbing than I initially had in mind.

If I don't know the way forward at any point, I stop, pore over the map — especially the contour layer, studying the terrain and roads around me — then memorize the next segment and proceed.

Good way to learn the county and its complex topography and geology up close and personal. Besides, love maps, and no better place for map study than on scene. If that adds a few extra stops, so be it.

 

[Stefan Mikes]

I use the navigation for many reasons, mainly because it is the only way to stay in on a group ride but not only!

Today, I planned an unusual route in my near neighbourhood. I was zooming along a railroad and overshoot a turn! Why didn't Wahoo "Gizela" snap "RROUTE!" at me? That worried me. I looked to the Settings on the device and found out I had turned the audio off by mistake Audio on and no worries.

Jeremy, there is an update waiting for you (I think). Go to the utility screens on the device (short push of the ON button). Scroll the first screen (the one with Display) all way down to Device Settings then to Check for updates. The current is WG77, published today. You need a WiFi connection to do the update.

I'm sure the day will come when I'll be happy to have the Wahoo's voice nav. Till then, it's off.*

Why didn't Wahoo "Gizela" snap "RROUTE!" at me?

Gizela, eh? Are you at liberty to divulge the kind of woman that name evokes in your mind?

.Jeremy, there is an update waiting for you (I think).

Thanks for the heads-up! I think I have WG76 now.

*ADDENDUM: Just struck me that I might have more use for Wahoo nav if I did as much utility riding as you do.

The SL does very little utility, as I still can't bring myself let it out of my sight. The old hub-drive does all that, but only within a totally familiar 10-mile radius.

It can be any German female name starting with a G Wearing a uniform and a necktie

P.S. Hilda would do as well

Might've been a little too quick to kick Gisela off my bike.

I see now why you like voice nav so much.

OK, you fantasize about the Helga behind the voice, and I'll see if Gisela will take me back.
