Just reserved a pair (I’m in the US). Says they will be available for actual purchase in ~30 days.
Is that the reason why I just started hearing it when I was riding indoors? Is the pedals not the bike?
Headline from @dcrainmaker indicates that this is the future:
“unquestionably delivers the biggest bang for your buck for an SPD-based pedal power meter, or for that matter, any pedal-based power meter.”
Other media have said function is near identical to an XT pedal which would also mean a lot. Seems like Q-factor is identical but there’s some variation between stack heights, with Favero being lower than any Shimano option. I’m in a place with bad internet right now but when I get a chance will come back and edit this post with the list of stack heights for the most common Shimano options and the three spd PMs now on the market. (Unless someone beats me to it)
Seems like an amazing new product overall!

EDIT with specs (there’s some disagreement in the reviews and official specs - need more time to do a good comparison as this is a bit cobbled together. I think there might be two different zero points from which stack is measured…)
Assioma MX: stack 11.2mm; weight 192g; q-factor 53mm
Rally XC: stack 13.5mm; weight 224g; q-factor 53mm
SRM X-Power: stack 10.5mm; weight 194g; q-factor 54mm
XTR M9100: stack 8.4mm; weight 155g; q-factor 55mm (or 52mm?) (stack listed as 15.1mm by Shimano)
XT M8100: stack 16.5mm; weight 171g; q-factor 55mm?
M520: stack 17mm; weight 190g; q-factor 55mm
Based on my experience with garmin xc200s i see 2 issues;
The pedal shape is not suitable long endurance rides. Such often require a softer walkable shoe so the frame you get on shimano xt/xtr type pedals is a big. deal to prevent hot spot on non carbon soles.
Not another bloody rechargeable.
They are probably fine for folks riding 3-4 hours intense racing type stuff, but not all day
Selling my xc200 back to 4iiii, lessons learned

Peak Torque seems to like them to, looks like they hit it out of the park
The Road Assiomas have a claimed 50 hour Battery life, for my part they had no issues with 10+h rides and I would guess that they did 20+h without charge during training over 2 Weeks.
I did not have issues doing 10h+ Gravel rides on the Garmin xc100, but I used carbon soled shoes… If you need pedals with platform then yeah I can see that they aren’t for you.
From everything I have seen this is by far the best Pedal based power meter, I don’t see how Garmin can keep charging 300 Euros more for the XC200.
Doesn’t this mean you should check cleat/ shoe placement?
Only thing I get from this thread is I must have the 1 lucky pair in the universe of xc200s. I’m not trying to bash favero, I’m actually interested in these because of the price.
It looks as though they recommend the same torque specs for installation as garmin.

My XC200 did work good enough (Outside of iffy Battery status reporting) they also read about 15-20W lower then my Assioma (Look), but I don’t know which of them was more accurate. I would not throw them away and buy the Assiomas, but if you are in the market for a new one I don’t see why you would still choose the Garmins over the Assioma.
Yeah the pricing of the TACX Neo 3M is a headscratcher makes the new Kicker Move look like an absolute bargain, It also is interesting that they do not update their entry level DD trainer, since it is imo not competetive. But it seems they still sell well enough. I really like the 530 I have but their pricing in anything else is just super questionabl.
No. Its not a cleat position issue. Yes badlyplaces cleats can also create similar effects, but that is not what i am referring to.
I worked in Manchester with a notable bike fitter on this particular problem. On very long rides, notably ultras and long addax’s your feet will swell significantly. We even looked at riding for 3 hours before fitting. The problem comes that hard shoes (carbon soles) dont flex or expand, so if the fit is not 110% you will get constriction point. Often you can get more comfort from a 7/10 or 8/10 stiffness shoe. These shoes will also help with walking or any hikeAbike sections. However it it this flexibility that can create a pressure spot at the cleat if the more if the shoe is not supported. basically spreading the load.
The truth is somethings work or some people and not for others. Its great when they do work.

Continuing off-topic: the older Neo 2T is currently available in many places bundled with the Motion Plates (without any extra cost), which makes the 3M even harder to sell.
@gpl any idea if the pedal bodies will be changeable to road version like the garmin rally or if they have plans to do it down the line? Apologies if answered in review, I can’t view it at this time!
Each to their own I suppose - I’d pick rechargeable over coin-cell any day.
I’ve been on both sides of this over time and my ultimate conclusion is that it doesn’t really matter except in edge cases.
I have adhd and that means it’s a challenge to deal with anything that requires charging time but doesn’t need a charge after every use. Charging my head unit after every ride is easy because it’s habit. Replacing my HRM battery is easy because I know I need to keep spares in the house and whenever there’s an issue I just put a new one in - also I know to pack spare(s) on any extended trip so I don’t have to go find one if one dies in use.
Remembering to charge my Assiomas is another story, especially in seasons where that bike doesn’t leave the house. TR reminds me at the start of a workout but not at the end (like wahoo does) so I keep finding myself at the start of workouts having to wait 15 minutes to put enough charge into my pedals to complete the thing. And then I still forget to put them on charge when I’m done.
Beyond ADHD considerations though, if I rode more than 15 hours in a single activity more than a few times a year then the battery life of the wahoo head unit would be an issue. At the other end of the spectrum, an ultra endurance bike race is enough to push the limits of ~60 hour battery life (di2 or rechargeable PMs) which means you need to carry the charge cable. Thankfully neither gears nor PMs have big enough batteries to make that a major consideration in terms of how much powerbank capacity to carry, so in that case it’s just about the bulk of carrying any brand specific charging heads. IMO that’s not enough to make coin cell batteries any better than rechargeable.
With that I think it’s literally just down to how easy it is to keep up with semi-regular charging routines.
The issue i have with rechargeables is what happens a year or so down the road when the warranty expires expire and charge capacity is at 60% of what it was when new. “Sorry sir buy a new one”. If the batteries are replacible, at home or in the field” thats where I want to be. It your choice what you put in rechargeable or not. I have seen people sitting at check points waiting for a charge rather than riding. You just want to pop a new one in , ride, and recharge the old one later after the event.
I hear ya with the charging
We have to charge tail lights, computers, watches, phones, head phones, power meter pedals, di2s, headlights etc.
Not to get off topic but yes I’m over charging things, part of the reason I use corded headphones, one less thing to charge. Luckily a lot of them use the same charging cord but sometimes I take up all the outlets just to get my bike riding stuff charged up. (Not all the outlets but having 6 things charging at once sheesh)

Man, these look pretty great. I just built up a gravel bike this winter and went with a Spider-based SRAM Force PM, but if I had waited I may have gone with this. These have the benefit of allowing me to travel with them and use TR on vacation.
The night before a long ride I charge my head unit, tail light, headlight, watch, and phone. Sometimes my di2 batteries and pedals too. I understand the concern of people doing rides long enough to use the entire battery charge, but I don’t see any reason I would forget to charge one thing when I have to charge so many others. If I was really worried about it, I would create a checklist on my phone and run through it every time.
This is one reason I got the garmin edge 1040 so I rarely have to charge it.
Just to clarify, are we talking one of the coiled super long kitchen phone style cords, or just a short boring one?
