I must be the odd ball here, I disagree that the center of the lane has (functionally) reduced traction. At intersections and parking spaces, yup reduced traction, but in between intersections or on highways and freeways not anything to worry about.
When changing lanes, we have to ride across the center of the lane(s) right? Have you ever lost traction because of that? I never have.
On curvy roads I'm an outside - inside - outside kind of rider. Never lost traction on these kinds of roads either.
Are there times when the center should be avoided...sure. After heavy winds and / or rain, certain roads have gravel problems. But on 101, 280, 880, 17...nope, I'll use the center when traffic dictates it (safer to do so).
I usually avoid the center in traffic because I want to use the space between lanes for an escape route, and riding on the side of the lane makes it easier to get to, plus it's easier to see hazards ahead, but not due to the theory of reduced traction.
. Still works though so that's cool. Probably take it to the track in the next few weeks to see if I can blow it up finally. If it lives after a couple passes on the 350 pills i'll up it to 450 and see what happens. Thing just won't die.
