Hmm... impressive!
Also impressive, ie., that the Panasonics will climb ANY gradient.
The thing is: Any gradient comfortably?
Or any gradient, but leaving the rider in a pool of sweat on the worst hills?
No, any hill comfortably. The problem is I always want to press on. Also the worst hill for me goes from one lane to three and then the left lane filters off left. Now would you rather do that at less than 9 mph - I can promise you that you will feel like a sitting duck? Personally I feel safer going as fast as possible as you stand a chance of getting into the middle lane without being run over.
