@slipdog, I thought about that, and after I saw your reply at the beer-break point of our ride, I had a serious look at the other bike: I don’t think the universal mount will fit. The electric SRAM shifter (AXS) is as long (parallel to the chain) as the universal mount offset, i.e. the vertical arm of that mount -which would probably fit above the shifter, maybe after some rearrangement of the bottle cage- would run right smack into the rear of the shifter battery compartment. One could try a direct derailer mount with a ziptie, or maybe try to use the simple arm that ships as a third option under the derailer on the seat tube, but the owner of the bike is also not as gung-ho on getting more data as I am. He was humoring me by riding along and letting me readout the SRAM Quarg power meter, but he did not seem enthusiastic about bolting/ziptie-ing some brandnew-to-the-market gizmo to his fancy bike. So, probably not going to happen. He’s more the cautious-conservative kind of engineer.
I was able to record about 80 minutes of SRAM Quarg vs Cycleclick power meter data, in two separate sections. The first look inside the BikeOn Power app makes me cautiously optimistic: the raw integrals differ by 4% and 2.4%, respectively, before any data cleanup, and, while riding, the smoothed data (5 second option inside the app) seemed to match nicely when we were riding alongside at a steady pace. Now I need to get motivated to pull the data into Excel, and then start the tedious work of defining good matching sections. I’m not sure what match I expect, because I definitely have more cross section and wind resistance…
Access to DCR Analyzer (v2 beta) and DC Rainmaker Analyzer still not working. Account seems to exist, but in limbo. When I try to login, I still consistently get that server error, when I try to reset the password, no email ever arrives, but when I try to register a new account, the system at least acknowledges that my email address already has an account. I guess that means back to the old Excel…
Thanks! I keep trying occasionally, from the link in the confirmation email, and today I get ‘network error’. Maybe they have all the users they want or need…
I tried compare-the-watts, and it’s nice, but to get more than a few data points (at different power levels, hopefully), it makes more sense to define data ranges in Excel and do the analysis there.
It’s really simple. Send the PM to trusted reviewers like DC rainmaker and GPlama. Shut everyone’s mouth. No barking in the forums. Cyclist and tech nerds are different breed we need proof that this works. If you want our money better have good reviews from the top dogs. That’s how you should do it. I think they abandoned the project. No argue in the forums with nothing to back you up. If this works for gravel bikes I am a buyer.
If you have a garmin intervals.icu has added support for the extra sensor connect iq app. That should allow for easy comparison of dual recorded activities.
Still would need to compare to a known good power meter to validate it but would allow comparison between the two you have to at least see how closely they align.
