Any luck?

Thanks for the reply. spoke to Paligap UK, and they said it would need to go back to be recalibrated again.
They mentioned that it seems to be an issue between the Garmin 800 and Powertap when calibrating. And suggested not calibrating before each ride as I have being doing and making sure the auto zero setting is on.

I'm gonna pm you but basically I don't think there's anything wrong with your Garmin !

Does anyone switch between a Shimano and Campy freehub on your PowerTap? If so, how difficult/bothersome/etc. is it to switch? I would be switching over and back maybe six to ten times a year if I went this route.

I recently purchased a G3 through WheelBuilder and am using it with my FR310XT. Is there some sort of Getting Started documentation? Specifically, I'd like to know:
1) Should I update the firmware or should it be good to go out of the box.
2) Do I need to run through the calibrate step before every ride?

A lot of the posts in this thread make sense but I feel like I'm missing the first basic steps. I've tried to google this subject as well as search the forum but I'm coming up empty.

One thing that has me puzzled is that I compared two rides over the same 46 mi route, one week apart. My avg power onthis week's ride was 27 watts higher but I was only 2 minutes faster. There was more wind which could have accounted for this but I'm not sure.

Thanks!

Hey Jesse,

I am happy to say that I went ahead and purchased the newer g3, I also purchased the Joule-non-GPS and some sensors and a powercal, The powercal is working great, one of the sensors is working-the other one is not. The hub is working great, however, the Joule started acting up. I cam home from my first ride with it, and as I was coming in the door ot showed the low battery symbol, I said fine, I'll put in a new battery, I did that-it was still having the same issue, I pressed AC, i tried reset a/l bootloader, but it could not find the device. To top that off, it is now showing Memory full, I have it cleared, there are no rides on it. it is showing up in poweragent as having 25.5 hrs of rides, when I go in to download-there is nothing there, I thought maybe if I went in there it would give me the option to clear it that way, no ride showing up.

I cleared it from the Joule itself, but it still shows up on the screen as memory full.


I am very frustrated, I do appreciate the customer service ye offer, but to ring from Ireland, costs a lot and I was on to Jamie in Tech support for nearly 2 hours trying to locate files that were not importing into the new version of poweragent, he was able to get me sorted, but what am I gonna do about this Joule now? I have a race tomorrow and was hoping to use it.....I see there were a few other people with similar issues, were they able to sort it? I really don't want to be without a computer.

Hello,

I would need a replacement for the battery holder of my wired PT.
From the website it looks like I cannot use one of the newest one (for SL+ etc).
Could you please let me know what is the model and where I can find it?
Thanks in advance

I have the generation before the current G3 generation and I do it all the time. It's much easier than taking a cassette on and off. Just remove the end cap, slide the cassette+freehub off, slide the new one on, and pop the end cap back on. Rock and roll.

I have a 2 month old G3 hub that I've been riding paired to a Garmin 910. It had been working without issues. This morning, I attempted to ride and the calibration screen came on like usual, and the calibration was around 506 like usual. However, no power was ever displayed or recorded when I attempted to ride. I tried again at re-calibrating, and no change. I also moved the Garmin around just to make sure it was close enough to the hub. I still could not see power on the Garmin. I've attempted hard resetting the Garmin, but that did not resolve the issue. Is there another step that might fix this problem?


I've searched the thread & the web, but I haven't seen an answer to this.... If i missed it, just point me to the right post. thanks

New battery for the hub.

Very easy, 20 seconds! Pull out the freehub and replace the other.

Not sure if you ever heard back on this but you should be good to go out of the box. People can get a little crazy with the firmware updates. I mean, it won't hurt anything if you do it but I've had mine for well over a year now and haven't updated it yet. Should I? Maybe. But if it ain't broke. I also have a PT Pro that I can not update myself. It is working fine too.

Regarding calibration, I calibrate mine before every ride. Why not? It takes 30 seconds and you can make sure everything is working.

Zeroing, which makes sure only that 0 torque is 0 torque. That isn't everything. =)

Updating your firmware would help make sure more things are working though!

thank you. that was it. With it being so new and still alive enough for the Garmin to see it, I didn't even think of a battery being the issue.

I have been having trouble with my g3 readings on my joule, today I did a race and the average wattage was 233 on one joule and 212 on my joule GPS, that's quite a difference...... anyone know why this would be occurring? I was wearing a powercal HR strap, and the HR readings were fine, I checked that the power averaging is every 5 seconds on both joules....... anyone? thanks......

Did you upload both rides and look at them closely?

Without doing so myself, I'd guess that the lower wattage unit has some missing data points and more zero readings, probably an interference issue.

Yeah it has some missing data Alrite- good thinking, thanks. Any idea what would cause it to miss from one computer and not another?

I'm only guessing here but it may have to do with where its mounted on the bike. Some guys say that a 910xt has problems receiving data when its worn on the wrist and not mounted to the bars.

Mine was in my rear pocket..... I'll try again tomorrow, may have been overhead lines....???

Hi Jesse,

I changed my batteries in my PT Elite + because my Garmin wouldn't pick it up when I went to calibrate it. After changing the batteries the first time I calibrated it my PT read 490, thought I was okay. As I was riding the power #'s didn't correlate with my ride. At the top of the first hill I recalibrated it and it then read 390, at this point I new something was wrong. Any ideas? Do I have to send it in for service?

Thanks,
Chris

We are currently testing this, should be out in a week or two at most....

If you haven't already, you should arrange a return.

If you're not already aware we have some new hub firmware for the G3 and GS that should solve this:
