Today I rode my Cosmic Stallion (Bojack Horseman) with the new road plus wheels I built for it. WTB Frequency i23 650B rims with WTB Byway 650Bx47mm tires. I love the look and they rolled great. It will take more rides to fully assess how they compare to 700c wheels and tires, but the initial impression is good. FWIW, I had my second best times (out of 70) for two Strava segments along the way.
