It's going to be a great exhibit. About two dozen bikes. NorCal focused. There are about 10-12 truly great/important bikes, 6-8 "nice examples", and about 6 decidedly "meh" (the modern stuff and more mass-produced stuff -- but they wanted to show where we are today with MTB's). I'm sure curating this was very, very difficult (Joe Breeze was instrumental in helping the SFO Museum folks).
I was there on Wednesday hoping it would be fully installed -- but at that time it was only about 75%. It's displayed mostly chronologically, and it was the newest stuff that wasn't yet up.
