It depends on how you make use of your time at these shows . . .
The info in link below is from last years SeaOtter. Same show/festival, I had a great in-depth discussion with Roval not just about their lineup, but about direction of the wheel industry. And tons of fun meeting up with fellow cyclists off the bike. SeaOtter is very special.
Just in NorCal, this clashes with Levi’s Gran Fondo. Which might not be of concern for people racing at Sea Otter, but is potentially for people doing / being able to do the non-race events.
