@iceaxe you’re talking about lbs, @gpl is talking about kg.
@TimmyR I got a calibrated weight from https://www.scalesandbalances.co.uk/
Because I keep comparing data, I thought I’d share the results after a factory spin down on my KICKR Core. Previously my KICKR Core was reporting higher power than my RallyXC 200s. Today I did a factory spin down and then rode a 1-hour workout (Goat Citadel). Below is a link to the DC Analyzer. What I now see seems completely reasonable and consistent. I used Zwift to record my KICKR Power via Ant+. TrainerRoad recorded data via BLE on my iPad (PowerMatch enabled), and my Edge1030 recorded data via Ant+. At this point I’m still happy with what I am seeing on my set. I’ll have some more comparisons against my Tacx Neo next month FWIW.
Follow-up question. Is this a valid comparison? On anther Forum I am told that PowerMatch makes this an invalid comparison of data.
My thinking was that TR is reading the RallyXCs just like my Edge1030. Zwift is reading what my Kickr Core is producing. If it was a perfect world, all three would match perfectly. As it is not perfect, I assume that the Kickr Core and Rallys would have some inherent difference and thus it’d be evident by comparing my Zwift Power to my Edge1030 (or TrainerRoad). I assume someone much smarter than me here could shed some light on my thought process.
Perhaps @gpl or @dcrainmaker can tell me if my method is valid. Thanks!
If I’m understanding what you did correctly, it’s:
A) Zwift/data paired to KICKR via ANT+
B) Edge 1030 Paired to Rally via ANT+
C) TR paired to Rally but actually PowerMatch via BLE
So, in my mind, I’d throw out the TR data, because I’m honestly not sure which source it writes to the file in that case (Trainer or Pedal). But that’s fine, assuming you just kept it KICKR-only for the Zwift data, then you’ve got a valid data comparison between the Rally and KICKR.
If so, your data looks pretty darn good. Roughly 1-2% difference, with Rally being higher than KICKR (which is as it should be). Larger difference at under 10-sec on the power curve for the TR source, but again, totally normal - especially with different recording protocols too.
THANKS RAY! That’s exactly how my data is recording and exactly what I thought. My KICKR was reading much higher until I did a Factory Spindown and then recorded this workout.
I am involved in a discussion on the Garmin Forums where I was told (after I explained how I was recoding the data from the KICKR vs the Rallys) that it was completely invalid and there was no way to know what the Rallys were reporting because of PowerMatch. That didn’t make a ton of sense to me.
I really appreciate your quick response ad reaffirming what I thought was true.
Cheers,
Tim
Yup. Exactly what I see except RallyXC as source in my case.
There’s a great sale if anyone’s interested at Trisports.com
Came in my email today. Think you have to be a podium club member? I’ve only bought a handful of things there.
yup, I got the same discount from biketiresdirect.com for being a ‘Gold’ Member. I already have a set but a buddy of mine was happy to have me snag the deal for them. $899 is a damn good price on the XC200’s
I’m delighted to report that I have finally managed to obtain a refund. However, the entire experience was like pulling teeth and I can safely say that I will never purchase another product from Garmin. Definitely gets my vote for the worst customer experience I have ever had the misfortune to have been subjected.
Out of curiosity, were you dealing with Garmin U.S.? I’ve had great support with them in the past with a Fenix5 issue.
Fortunately I seem to still have a working set of RallyXC 200s.
Sorry to hear you had such hard time.
Same here US customer service has been top notch with my problems. My pedals have been great too that sucks you had a bad experience.
@bdb Thanks. I was just curious. @gpl’s review almost prevented me from buying these, however I had an opportunity to buy them at a large discount so I took the chance. I must have watched/read his review along with @dcrainmaker’s and @DesFit’s at least 5 times each. Feeling lucky they are still holding up well.
Hope your Quarq works out perfectly.
Cheers
New software update for rally pedals!
Not sure what it means but maybe @gpl can break it down one day for us if there are any significant changes?
Updated mine yesterday. Planning a ride on the trainer today. I’ll try to compare them to my KICKR if I remember. Hopefully they’ve sorted some of the issues that I’ve read about.
I tried searching what they wanted to update with the firmware, no luck. I have a long ride tomorrow so I’ll try and see if I notice any changes.
Anyone find any pedals with similar q factor/stack height to the Rally XC?
Got the left-side sensing ones and planning to move between 2 bikes, so was thinking I’ll have 2 right non-sensing ones and just swap the left one + have a left non-sensing one for rides where I expect rock strikes/don’t care about power. The official Garmins seem pretty expensive to me at $99 for one pedal.
I recently discovered that my Neo1 reported about 15W high at. 250W when compared to both a Power2Max NGEco and Assiomas all running at the same time. The P2M and Assiomas agreed with each other to within a couple of watts while the Neo1 was 15W high.
This is common for high fly wheel speeds. Mine does this and I use assioma duos for power matching to compensate for it.
