Have always enjoyed their clear lenses and just noticed they're now offering tinted. Picked up a pair! Any riding below 50f and my eyes water quite substantially.

Hahaha I can see how it might seem like those two do look a bit underwhelming but I actually have trouble with overcooling and getting kinda chilly with them. There are times I have to lower it occasionally in the middle of a ride.

A bigger fan would just be more of a nuisance. Plus when I open those two windows behind a good amount of air comes in and then I don't even need the fan anymore haha.

Thanks for the compliment!

Thanks!!!

I was torn between the 2nd gen Kickr and the Neo. Rode both. Neo is the best, and by bike lengths at the end of a sprint for a visual comparison.
Oh and another big factor for me choosing the Neo is that it's almost dead silent. Which is helpful because there are people sleeping in the bedroom below me while I ride at like 6am and to date never had a single complaint about noise.

How are you liking the Neo? I just did my first Zwift session last night with mine and was pretty disappointed. It was reporting about 50 watts less then I was normally getting using a calibrated Tacx Vortex Smart. Going to do a direct comparison using P1 pedals tonight. I'll probably be sending it back if it reports significantly lower than the pedals.

50w seems a bit much but don't be in a rush to send it back. What is the difference in %? There are lots of variables that could account for the diff between pedals and a trainer power meter including different algorithms, different points of power measurement, etc. From what I understand it is normal for pedal based meters to differ more than crank based. My Vector and Kickr don't show the same power readings. If you want 100% comparable data use the P1s all the time.

PepeM 12-21-16 11:48 AM

If you have the pedals, why not just use those for power measurement?

At this point I have not compared it to my pedals. Going to try that tonight. Previously on my Tacx Vortex (regularly calibrated), I averaged about 210-220 watts on a typical Zwift ride. No way I could maintain that last night using the Neo. Ended up with a 157 average. That is about 25% difference.

I would expect the pedals to report a little higher, but no more than 5%. There are some people on the Tacx forums reporting similar issues, so that is why I asked.

Yes, that is an option. However I don't feel I should have to come up with a work around to get accurate numbers from a $1600 trainer. Also, I have a dedicated trainer bike so that I don't have to switch things out. The pedals are not normally on the trainer bike. Having to switch the pedals multiple times a week is not something I am trying to do.

I'll know more after testing with the pedals tonight. Maybe the Vortex has always been reporting high, and I am just really slow! :p

My Tacx Bushido definitely registers a bit lower than my P1s, but 50w seems really strange.

I'd wager your Vortex was even registering a bit lower than your P1s - that seems to be Tacx's thing, but 50w is a big difference.

PepeM 12-21-16 01:43 PM

How was your Vortex 'calibrated?'

I can tell you that my Genius is nowhere near my C1 chainrings. I just don't pay attention to it anymore.

The beauty of using different devices to measure power. The more you use, the more headaches you'll get.

There is a calibration tool in the Tacx smartphone app that uses a spindown.

PepeM 12-21-16 02:06 PM

Alright. Thought you meant calibrated with respect to your P1s somehow. Yes, I also calibrate my Genius before every ride. The numbers from the trainer are nowhere near those of my power meter. I wouldn't trust any numbers out of the Vortex to be honest, unless you have good reason to (ie, you have compared them the numbers from your pedals.) The Neo should be more accurate but I've never tried one so I don't really know.

How do the numbers the Vortex gave you compare to those you get outside with your power meter? If only I could put as many watts as the Genius thinks I can, I would be winning a lot.

SpeshulEd 12-21-16 02:59 PM

Another easy way would be to hook up the P1s and watch their watts via their app. Then watch the Neo (or Vortex) via the Tacx app, or Zwift or whatever.

The P1s should be accurate. If the Neo is drastically less than both, I'd say that has the issue.

That is my plan.

eric1971 12-21-16 07:39 PM

Ok, so I think I figured out what was going on with my Neo. I starting thinking maybe this was a Zwift issue, and not a Neo issue. One thing I was seeing is a huge spike in resistance during the "road feel" areas. I searched the Zwift forum and found some people reporting similar issues. Low power reporting and strange resistance issues. When pairing the power source, there were 2 options. "Tacx PWR" or "Tacx Neo". Naturally, I chose "Tacx PWR". This is wrong. "Tacx Neo" is the correct choice and this seems to have fixed my power issues. Only had time for a quick test tonight, but I was able to quickly bring it up over 200 watts even without a warm up. Full ride tomorrow will be a better test.

Woo, good to hear!

Loving it with Zwift and the training programs on offer (although I have a serious gripe with Zwift I will address shortly).
Still have not yet noticed anything with the "road feel" aspect with the NEO on Zwift even though I was supposedly riding bumpy looking roads on the London course once so we'll see. In terms of the numbers power wise it appears to be fine compared to the Computrainer I used to use a while back. Can't say for sure because I only currently have one device outputting power (i.e. the NEO) so you're probably in a better position and you seem to have noticed it actually might be Zwift.

COMPLAINT ABOUT ZWIFT:
If you're going to use Zwift note that if you don't upload your ride or training to their servers as soon as you're done it will never get uploaded to Zwift.
You have one window of opportunity to get it to them, miss this, and you can NOT later upload the .fit file to Zwift.

I learned the hard way. What happened was I started a ride at lets say 21:30 and they were running a maintenance on their servers from 22:00 - 23:00. My ride finished at 22:30. Exited and selected the upload function. No bueno. No communication message blah blah. Figure I'll close it, use my computer for life things and upload later as you can with Strava etc. Nope. When the server gets back online it's not an option. Search online forums and find out Zwift knows about this stupid issue but has not fixed it. Their Dev's just say something stupid like "it is a feature we hope to add soon etc etc" ... in a forum from mid-2015!

My tip, never ride around scheduled server maintenance; if your file doesn't upload, leave your computer alone and don't exit that upload screen until Zwift is back online. Also you'll know you're disconnected from the Zwift server when you're riding and suddenly every other rider disappears.
