I’m trying to get Zwift Cog/Click setup to work but the resistance is super wonky when using virtual shifting.
My setup is a Canyon road bike mounted to a Tacx Neo 2T trainer, with Zwift Cog / Click V2 (trainer and cog / click setup purchased a couple months ago). Due to Click being bluetooth-only, I have everything running through Zwift Companion on my phone. I use a Windows PC to display the actual game. I’ve also tried running directly to bluetooth on my PC but the issue persists. I can confirm that nothing else is connected to bluetooth on either devices.
Tacx Neo 2T firmware is up to date. Zwift Click firmware is up to date. Zwift Companion + PC app are both up to date.
When I have virtual shifting enabled, the trainer will regularly (like once a minute) increase resistance by a lot, then decrease resistance by a lot, then return to normal. When maintaining steady cadence, there is about a ~150W swing in resistance. This happens very regularly.
I’ve pretty much tried toggling every single setting in-game, as well as in the Garmin Tacx app, but nothing helps.
I’ve noticed that even with trainer difficulty set to 0, the trainer still randomly oscillates resistance… by my understanding of how trainer difficulty works, shouldn’t the resistance be steady and only change when I shift? Something is really wrong here.
When I disable virtual shifting or unpair the click controllers, the trainer resistance is very steady. I think I’ve narrowed it down to the Zwift Click system, but not sure what to do at this point - what am I missing here? I’ve spent all week debugging and am honestly about to just toss these things in the trash and go back to a traditional cassette.
I have the same problems. I am using zwift ride with neo t2. It is all ok on the beginning of the ride bit i am getting random resistanc spikes after one hour of riding. Also tried different conection configurations. I turned off race mode, connecter power with ant+. In the end the only bluetooth connection i had was a resistance.
i used zwift play/neo t2 setup before purchasing zwift ride and everithing worked as it should. For the last two/three weeks resistance spikes started to happen woth zwift ride.
This can be from not using a high enough gear ratio. You should have between 2.5 : 1 & 3.0 : 1.
I had the same when I first started with virtual shifting. I was using the 34 in front & 21 in the back. In ERG mode I was fine, but with virtual shifting I got power drops/spikes.
When I went to 34/13 (Zwift Cog) I was fine, also with 50/17 (had a little more flywheel effect).
I uploaded my latest log to TrainerDX, which shows “no disconnects/resends/resets” under the Bluetooth section. I used a log from a ride that I did with direct bluetooth connection to my PC to rule out any connection issues with my phone. Because I have the same exact issues via both direct bluetooth to PC and bluetooth via phone, it doesn’t seem to be a connectivity issue.
Your ratio may be fine, but you may get more flywheel effect.
Personally, I don’t like that, so I found the lowest ratio that worked. I like to mimic hills, where there isn’t much flywheel effect, but for someone who rides fast on flatter terrain, flywheel effect is beneficial. It’s just personal preference.
Found something at the bottom of this thread: forums. zwift. com/t/virtual-shifting-and-neo-2t-only-partially-working/656568/38
(sorry can’t post the actual link to the thread because Zwift doesn’t trust me yet)
Looks like a user was experiencing very much the same thing as me and seems to have solved it by “extending” their crank arm with a piece of metal so that the Tacx Neo cadence sensor is actually able to pick it up. I am using pretty short cranks (160mm) so it could be the same issue. I’ll test this out and report back.
