I was juct thinking the whole 6800 crankset for a double sided output is $999 that is more than double. Power meter City has the 6800 left crank for $300. Some one give me a thought on what they use or if I am going up the tree correct?
I felt like a single sided PM was too much to spend to still not know my power. I don't stray too far from 50/50, but it varies from moment to moment. If I'm doing 45/55, a left only meter will be off by 10% at that moment.
