My first post here, please excuse if the answer is obvious.
I’m looking simple how-to guide for those of use that have a fixed gear bike and how to get things setup and working correctly.
I think I need a method to set the cadence without gear shifting. Is there a control within the app to do this? For example if I want to train at 125w with a cadence of 60rpm can I adjust things to allow?
Thanks for any help
This is how ERG mode works, it automatically controls effort/power based on your target, so you can pedal any cadence you want and the effort will either be easy or hard. Now that said it’s possible that your fixie is not the perfect gearing so you can’t go easy enough but if you are reasonably strong then it’s unlikely that is a problem. Just notice if you have an easy target and it won’t go as easy as prescribed automatically then that could be the reason. I have never done the math and don’t know your exact gearing but I would not be surpirized if 50watts or something is not the easiest but for most, this is fine.
I am not sure how this works from a cassette standpoint meaning you need a cassette that will mount to your Saris but also has the same tooth size as the chain on your bike. Maybe this is not a problem in general. I know Zwift Ride solves this problem at some level but I don’t know if that works on the Saris.
Thank you Alex, I will give the ERG mode a try. The difficulty I am having with the workouts is mostly in the warmup mode. It gives me a very light target like 50w in my case. The result is hard to describe, almost like the flywheel is running too fast for the load and I get a “clunk clunk” as the pedal force engages the load, almost impossible to avoid even with very careful smooth pedaling. Not sure if i succeeded in describing?
Mechanically, connecting the Saris to the bike its just a matter of alignment with spacers, and using the same size cog as you suggest. Mine is reliable and strong.
So, yes try ERG and the white line should be at the top of the blue bars
It probably won’t be this smooth but something like this. If you are not seeing this then ERG mode is not working correctly. Let me know, there are a few things we can do to troubleshoot if there is an issue. I don’t know about the clunk, clunk. Looks like a great mount 
and the gear ratio looks like it should be fine.
