Adding in my recent experience. I recently switched from a Kickr18 to the Neo 2T. For the most part I am happy with the unit. Definitely quieter than the Kickr (pre-knocking noise too!). I have noticed some dropouts in TR when running TR via ANT+ alongside running Zwift via BT, although this does seem to be related to on-screen data as there is no drop in resistance and TR didn’t notice any official dropout in my data.
Biggest issue I have had though is that occasionally (1-2x per week) my resistance will lock up for no reason. This isn’t a virtual slip issue as it is not occurring when trying to mash the power/torque. Rather I can be spinning along at SS around 90 cadence and then the pedals just stop going. I typically backpedal for about 5 seconds and then get going again at the target power (I’m running ERG). I chatted with the Garmin folks today and they suggested this was a known software issue and that it is being worked on. I have switched to now running TR via BT, so hoping that helps and also solves the data blank/dropout issue.
Fingers crossed the lockup doesn’t happen on my next Ramp Test!
I remember having those high torque locks with my NEO 1, I solved this issue by using the Tacx Ant+ antenna, also the TR control was on point since then. Nowadays, I’m using the same antenna to connect TR with my Neo 2T, alongside with Zwift connected via Bluetooth. No dropouts whatsoever, maybe you’ll find something useful regarding those here or here
Unfortunately my 2T died after five minutes use from new. Have been in touch with others with the same problem. Garmin have been slow to respond with anything useful and its a big outlay so first impressions are not great! I’ll post again here with any progress on this.
I have the latest firmware on both, performed zero offset on the assiomas, and I see, in high power intervals (well, high for me), the assiomas read 10 to 15 watts higher than what the Neo 2T is reading.
It’s got me to the point that I have done the warm up with the Neo controlling it, but after the first real interval I switch back to the Assiomas controlling the trainer power.
How high is high power? Even if it’s 300W, then a 15W delta is still only a 5% difference - probably within the margin of error of each of the Neo and the Assiomas?
I’ve been using TR for a number of years using a set up of Stages Power meter + Elite Turbo Muin which has worked really well for me. I recently decided it was time to upgrade to a true smart trainer and so got myself a Neo 2T. I came off my first session on the Neo 2T absolutely wrecked and put it down to poor recovery etc on my part but the same thing happened after my second session too so I started doing a bit of research. First thing I did was check my kit : no cross chaining, chain on smaller front cog and larger rear cog, good Ant+ connection (using Tacx Ant+ antena) etc. The I did a workout with TR connected to the Neo 2T and my Garmin Fenix watch connected to the Stages power meter (having done a zero reset). Having completed the workout I then collated the 2 sets of data in .tcx format and plotted them on a graph in Excel looking at the first 3 step ups in power as part of the warm up you can see that the Neo 2T is consistently under reporting the power compared with the Stages by 5-10% (I’ve tried to paste a screen shot below).
I completely accept that there will be a variance between measurements and was assuming/expecting 2-3% but 5-10% seems over the top. Looking through this post and others it seems I’m not alone in seeing this - has anyone figured out what causes it - given that there are just as many who don’t have the issue?
Hi @brenph, I assume you mean using the TR power match functionality? It feels like a bit of a cop out to me given the supposed 2-3% accuracy quoted in various other reviews (eg DC Rainmaker and GPLama) but guess if it works then it’s one to accept/live with.
Yes it would be powermatch. I dont really think about it… it just works. And I know about the claims but I dont really mind too much as I (currently) have a single chosen source of truth.
Not very high. Spencer +2. 1 minute interval at 262 watts.
If I put the NEO to control it, it brings it to around 262, but the assiomas read btw 270 and 275.
You’re right, it is a 5% difference. but this is a Tacx Neo 2T, one of the top of the range trainers with precision of around +/- 1. For the money, it is unacceptable to be 5% off.
Hi, Spencer 2+ first 1 minute interval showed the difference. if I continue the full interval (3 mins at 120%, 260 watts), I would’ve cooked myself as I’ve been using the assiomas to control the power on my old vortex smart trainer.
so, it’s not 30 seconds, it’s more than 1 minute that you see difference.
and again, 5% may sound nothing, but we’re talking about a high end product with advertised precision of +/- 1%.
if 5% is the variance, it means that I will have different porwer zones for outside (assioma) vs what I train inside (Neo). Having a neo being controlled by the assiomas do not make sense to me for the money I spent on this trainer.
Yup. But… maybe our power meters are reading high rather than neo reading low (I dont think so in my case… I had 2x Flux/Flux S that read within error bars of my power2max). So without a 3rd (and maybe 4th) power meter to tell us which one is trending weirdly the test is incomplete.
I’m on my second one. The first one had a chunk of the light blue plastic shoot out across the room. When I flipped it over, there were something like seven cracks, and the huge hole where the piece shot out.
Tacx/Garmin replaced it with a new in box unit, and now it’s cracked too, same spot. Yikes…
