I have an issue with the pedals being connected to both my Garmin and TrainerRoad. They always fail. My calibration sequence is:
1 - Unplug my ANT+ USB stick.
2- Turn on both the pedals and my Garmin
3- Calibrate through the Garmin
4- Plug in my ANT+ USB stick
5- Verify everything is connected to TR
6- Ride
Hi,
I’ve just received the spindle today so haven’t had the chance to fit it yet.
I’ll let you know.
So now my left pedal is doing the same as what my right did a year ago - power drifting down throughout a ride. Replacement spindle on the way - assume it will fix it like the right spindle replacement did before.
Fully assume that this is a coincidence… but going to put it out there just in case it resonates with anyone else having issues… both times I’ve ran into this issue I had recently calibrated using trainerroad desktop via ant+ which is not something I normally do - I usually use either my Garmin or Android phone.
But it was also winter both times…
So, a bit of an update.
I received a new right spindle on Friday and went to swap it this morning.
The first thing that I found when I removed the spindle is that the bearing next to the oil retainer (pod end) was stuck on the spindle and it was dirty in there. The middle of the three bearings was really rough too. When I took the left pedal apart as a comparison it was much cleaner inside, the bearings weren’t stuck to the spindle and they were much smoother. Pedals are about 8 months old, c2600 miles.
I thought whilst I was at it that I’d replace the bearings so nipped out to a local dealer and bought a kit. When I got back I noticed that the oil retainer in the new kit was a different profile to the original and took an additional O ring. Here’s a profile picture. The original is on the left.
Speaking to the dealer they’d not noticed this difference before but said it wasn’t a problem and that either could be fitted as they had used the O ring type themselves on rebuilds. They didn’t think that there’d be any contact with the body and the O ring to make it a more effective seal.
Has anybody else seen the O ring oil retainer version in their pedals?

@Fritso. I have been using the same setup (Elite Direto, with Assioma dual-sided) since last September/October. Then in December and January the Assioma’s kept dropping their signal during workouts and my power readings would go to 0 even though the resistance was still there. I calibrate the pedals and the trainer before every workout. After a firmware update on the pedals, I am having exactly the same issue. I can nail workouts on just my Direto. But when I use my Assioma (dual-sided) and powermatch, on the exact same workout, if it’s a tough one, it will absolutely wreck me. I’m not sophisticated enough to really figure out how off the direto is. I guess for consistency sake indoors and outdoors, I need to do my next ramp test with power match on, and prepare my ego for the hit its going to take.
Yeah, that’s what I did too. Took the ego hit, retested FTP with Assioma’s and now I do all my workouts both indoor and outdoor with em. Kinda sucks imo, because the Direto was advertised as being very accurate.
But seeing as I’ve already had so many issues with the Direto, I’ve got way more faith in the accuracy of the Assioma’s. They’ve been tried and tested.
I have the Duo’s and i have consistently recorded different L/R balances when on the trainer (Kickr 17) v outdoor rides. On the kickr i am usually 50/50 or 49/51, but outside I am usually 53 or 54 L and 47 or 46 R. I usually clip out on the R, and thought that may contribute to the L dominance, but even when I deliberately clip out only on the L the L dominant imbalance remains on outside rides.
Anyone else experience this or can offer an explanation?
Interesting. Never tried with my Assioma but did test my Pioneer L/R against my Drivo. My imbalance is pretty consistent.
Maybe not just clipping in, but also if you go from coasting to pedalling again you tend to lead with the dominant leg? And with no coasting indoors, that goes away?
jazir1979, good point, its obviously an unconscious thing, but that may be it
Also may just have to do with how you produce power when the bike is stationary vs when the bike can move under you more naturally. Also depends on the power levels, I am almost 50/50 at threshold and above but i’ve seen as skewed at 60/40 on the trainer during the rest valleys after an interval
Elite Nero rollers 49/51, Tacx Neo 46/54
Same setup. Elite Direto and Assiomas, with power match for TR. I dual run Zwift sometimes from the trainer and found my Direto is higher by around 10W like you. I trust the Assiomas for TR, and an extra 10W for Zwift is fine with me.
I see similar with a KICKR Core where the KICKR is ~10W higher than my Duos. While I’d love the “extra” watts, I always pair against the Duos and just powermatch with Erg mode for workouts. If anything, powermatching to the pedals allows me to be a little more fluid than trying to ride against the trainer in erg.
My Assioma’s should be here on Tuesday. Anxious to get them installed as I’ve been training with virtual power for the last year.

Hope you are planning on re-doing the FTP test ASAP
I do the same for TR workouts. I trust the pedals to give me a truer wattage, so I’d rather have those dictating my TR workouts. The “extra” watts are just a bonus for Zwift rides, which are mainly to pass the time during TR workouts.

You CAN pair the pedals in both systems, I simply pair them as my power and cadence source in Zwift, and then pair them again to TR, this way the power even matches. It was interesting to see the differences between the trainer and pedals, but I just run everything on the pedals now for consistency.

Yup. I think I’ll do a ride or two still on virtual and just monitor the assioma, just to see the difference. But yes I plan on doing a ramp test to get the correct numbers. Hoping my virtual FTP is low but we will see.

I just got a pair last week, and one thing to note if you want cycling dynamics to work properly on Garmin head-units make sure to change the mode in the Assioma app to transmit both data sets. I was having issues was comparing it to a quarq which I know is reliable and finally decided to change this setting.
The pedals are great so far and track very well comparing to my quarq. Last workout overall averages were within 1 watt for 5, 10, and 20 minute times.
I would suggest loosening the tension screws a bit to allow easier release. I came from look max pedals with a pretty high release, and these at medium were harder. I think that I will tighten them back once they break in a bit. They were very hard to release and I have been riding for a few years I didn’t trust myself to ride outside.
Looking forward to riding with these more! Happy Training to All!
