Felt fast... rode the Kuwahara for the first time in 6 weeks since the threat of rain is low today. So much lighter than my hybridized Hardrock. Weather was clear, lots of sun, little breeze, moderate humidity. I felt bad that I had to go to stop at work when I got there.
I heard a ping when accelerating from a stoplight... will have to investigate what broke, hoping it's just a tooth either on the cassette or on the crank, although the drive train is pretty new so any damage of that type would be mildly disappointing.
