Cold Winter Air Temps and Power Performance?

Thanks for the input. I have been completing a bunch of sweet spot workouts indoor on the Kickr and going to complete my own real world test soon. Who knows how accurate my power meter is vs the Kickr, but I will find out!

Bugeye72, I am located in Portland, but ride all over Maine, NH, and VT. I am pretty much 100% MTB and try and avoid the dangerous Maine roads.

Kuttermax, did you just swap the left arm for a stages gxp mtb? I am actually running a crazy setup right now. 29+ bike with 27.5x3.8 tires on 50mm rims. This lets let keep the narrow q factor and decent float. I have been struggling with knee pain due to weak hips and even with PT the fatbike bothers my knees. Running the new Raceface Cinch meter and it seems to work well at cold temps.
