I own anew 2022 Trek Domane AL 5 and purchase a Sarius M2 trainer and found it resistance was not right. Later I got a Garmin RK100 petals to hopefully analyzed why resistance was so bad. Sometimes I notice that I was getting resistance even going down hill, With the RK100, I thought the new Wahoo Rollr would be better. I call Wahoo and they thought Zwift could have conficts with Garmin 530 running at same time.
To me it seems like the Rollr made things worst or RK100. I got frustrated and decide to return and purchase a Rockr which has good repetition excepts for possible compatibility issues.
I am retired software engineer and iI believe Zwift has some bug with controlling smart trainer. I was on the downhill portion of Watopia map and was getting ton of resistance and previous I had speeds of 40 MPH. This is not right. This is area with Dinosaurs
I am hoping new adapters for new Rockr V5 purchase directly from Wahoo will make difference,
I debated switching petals to non-power petals,
PS I wish I could see in real time what the resistance and grade level is in Zwift.
-Ensure only one device is connected to Zwift…the M2 or the pedals. If you connect the pedals as the Power Source, connect the M2 as the Controllable.
For example: Connect the M2 as Source and Controllable; Connect the pedals to the Garmin and save data in Garmin Connect. Compare the power profiles.
-Why would a Rockr “fix” what you are experiencing?? No software in a Rockr…
-Depending on trainer setup in Zwift, will have resistance downhill. Zwift wants you to pedal as much as possible.
-Your M2-Bike interface needs to be setup the same everytime. Tighten only enough to prevent slipping. Do not over-tighten.
-M2 firmware needs to be up-to-date. Use the Saris app. DO NOT CALIBRATE IN ZWIFT! Only calibrate in Saris or Rouvy app.
“Why would a Rockr “fix” what you are experiencing?? No software in a Rockr…”
Rockr is direct drive to chain same as Sarius H3
Rollr uses external power source which is RK100’s I just think the M2 is unreliable on resistance
“-Depending on trainer setup in Zwift, will have resistance downhill. Zwift wants you to pedal as much as possible.”
That not logical, going downhill should have no resistance. I am ok with pedaling - it work one time and I achieving 40 MPH.
M2 was not tight - at one point too loose and going nowhere fast.
The Rockr is a plate with rubber balls. You have to supply the trainer. Not sure where you are seeing a “Rockr Trainer”.
In Settings you have the trainer setup to simulate the grades. So if it is a 10% grade, it will “feel” like 5%…but the Zwift response will still be a 10% grade. So you still have to put out the watts. For downhill, that “simulated” grade is further reduced by half. So a 10% grade downhill, at 50% setting, will react as a 2.5%. To get the maximum downhill, the slider needs to be at 100% but it will still “feel” like 5%.
In essence, it gives you more gears for uphills but limits coasting going downhill.
Can you please give us a rundown of your setup. Please give full model names.
Also can you post a picture of the pairing screen.
@Mike_Rowe1 He may think the Rockr includes the trainer…
Hi @Stewart_Hyde welcome to Zwift forums.
Shuji at Zwift HQ here. I’m looking through your server logs and see you have several smart trainers as well as the Garmin power meter pedals, and they’re connected to Zwift in different combinations. This is is one possible root cause of your resistance issues.
The other root cause is a third party app running on either your PC or your smartphone that’s hijacking your trainer’s Bluetooth signals. If you have Garmin Connect installed on your PC - either disable it from running at Windows boot up, or uninstall it for the time being to rule it out as the source of your issues. What happens then?
Next: try simplifying things for the sake of troubleshooting. Pick a trainer you want to use - doesn’t matter which - and disconnect the other one from AC power so it doesn’t get involved in troubleshooting.
Reboot your Zwifting computer - looks like a Windows 11 machine in your case?
If you have any other computers / mobile devices running the Zwift game app - power those off to eliminate interference from them.
Power off the bike computer on you handlebars so it is not bonding to your trainer. I agree w/ the Wahoo support folks that your Garmin 530 may be conflicting w/ Zwift. If you want to run a dual-power setup, there are ways to do that which don’t cause conflicts. We can get to that after you follow the steps below and get Zwift running as it should.
Power off your smartphone so any apps on it from Wahoo / Garmin / etc are not bonding to your trainer.
In the pairing screen:
Power signal of your trainer and pair to this first. Take note if it’s the ANT signal, or the BLE signal that has the lightning bolt icon). Try to stick with all BLE or all ANT for troubleshooting purposes.
Controllable signal of your trainer: If Controllable auto-pairs to your Garmin pedals - disconnect it and manually pair to your trainer instead. When using Bluetooth, your trainer doesn’t broadcast the Controllable signal until the Power signal is bonded, and even then, a 15 second delay is normal.
Cadence signal: Cadence is last. Again, take note of if it’s using BLE or ANT and use the same protocol as power and controllable.
Now start riding and see how the resistance behaves. What happens?
First of all, at no time did multiple trainers were on at same time. In fact, only the Sarius M2 can be used currently since I ship back Wahoo Rollr today. Wahoo Rockr was purchases because I did not like wheel on trainers - I was hoping the Rollr would be better option especially since I got the Garmin XK100 power meter to output from M2 - Zwift seems to be so unbelieved and for combination of indoor and outdoor biking ideal it would be nice to have same place.
Garmin is connected to Garmin 530 computer and monitor by my phone. Only thing connected though my computer is Zwift. Computer should not be an issue - it is a 2022 Dell XPS 15 with i7, 64G of ram and 3050 TI video. Only issue if Zwift has compatibility issues with 12th Generation Intel CPUs.
Does Zwift have combability issues with Power Petals?
Does Zwift have recommended setup using bike computer with smart trainer?
Shuj since it appears you work directly with Zwift, as retired software developer I would recommend option for uses to help track down issues especially related to connections and settings especially what is coming and going from devices.
Zwift will report the data that is sent so it will show the power value as measured by the trainer or pedals depending on what you select as power source.

Does Zwift have combability issues with Power Petals?
I use power pedals (assioma Due) and a saris H3 at the same time. I also used them with various other trainers.
Pair the power pedals as power source and the trainer as controllable.
Maybe Garmin has issues in Zwift. Another thought is possibility the latest update to Zwift is causing performance issues. This would seem logical time when issues started happening.
I have a few team mates that use the Garmin vectors and they did not report a problem.
I recently got a new Kickr v5 and it light and day difference over the Sarius M2. Sarius was all over the place on resistance and what was worst, it even had resistance going downhill. I am almost desiring to remove the entries before Kickr v5 (if possible)
Garmin Rally Rk100 is not active now, but now I don’t believe it was part of issue.
One concern is why others seem to go faster than me. Its possible Zwift has issues with internet speed which should be resolved in a month.
