The Assiomas will pair with the iOS TrainerRoad Application via ANT+, allowing you to see the Cycling Dynamics mid-workout 
.
I hate to be the bearer of bad news, but we don’t have any plans to include Cycling Dynamics moving forward. 
Developing support for CD would take a lot of development resources that we can’t divert from work on our current roadmap
One major problem with increasing our level of Cycling Dynamics support is that it would take a lot of legwork to build out the post-ride analysis sections to view and understand the data recorded. This has implications outside of just the apps; this would need to be integrated into the web side of things as well. Data analysis tools would need to be built to understand and utilize the data. All of these processes would need to be updated to make sure they work with all available CD devices on the market.
It would be a very large-scale project if we wanted to fully and properly integrate Cycling Dynamics into TrainerRoad and, as a company, we feel our Development Resources could be better spent on some very important projects in our pipeline.
Sorry for the inconvenience. The good news is, you should continue to be able to record CD on your Garmin head unit in parallel with TrainerRoad, so if that info is important to you, you can still record it and use it in your training.
