Jenny M--may have to start watching The View!
Thank you for breaking this ground. Perhaps i am the first clutch lever-less darksider. I have just over 5k on the Exalto at 31 PSI. I love the following:
Slow speed heavy traffic, bike stays very upright.
Dirt and gravel: much improved
Rain (especially standing water common in Mojave with flash flooding): much improved
Mountain Twisties: handles wonderfully
Longevity/cost: expecting great things
I did notice on the 32 hour ITU when going to medium lean to heavy lean it takes a lot of grip input with increased resistance. This is a non factor for a day ride, but after many hours in the saddle, it is possibly fatiguing--hard to say after one rally. Also when passing up a mountain, some power is reduced. With a rally loaded bike I am in a lower gear for higher RPMs especially with CT.
I believe MPG is reduced if you are a deliberate or aggressive rider, especially if in mountains. May be negligible if you are slabbing down the interstate with a bigger tire. In my short experiment, riding aggressively I saw a drop in mpg. This makes sense to me.
I am very impressed.
