Hello there. Is anyone experiencing regular resistance spikes with the 2T using the Zwift Cog (latest version). I’ve just recently upgraded my 2T to use the Zwift cog and click controllers, which all connected fine and setup was a breeze. Whatever I’m doing in Zwift I seem to be getting very regul…

There’s some discussion about it over here [image] Virtual shifting and Neo 2T only partially working Bugs and Support I have had annoying resistance issues with my Neo 2 T: while riding with a steady cadence and power output, the resistance briefly jumps up a…

You are not alone. No Solution until now.. Look at: zwift-virtual-gearing-with-exaggerated-resistance-increase-when-changing-gears

Garmin have closed my case saying it is the Zwift cog at fault, I mean, yeah suppose it is but the Neo2T can’t not be at fault somehow. The problem is still driving me mad but I have no idea what to do.

FWIW: I use a Neo 2 with the Zwift Cog/Click (v2) and don’t have this issue at all. I presume you’ve checked to ensure your Clicks are on the latest firmware?

Yes, everything is fully up to date, reinstalled everything including cog, bike, software, etc etc etc. Nothing solves it sadly.

I seem to be having the same issue. Do you ever find out what was wrong?
