Supply of Bonk Breaker products had always been spotty. I get them from that link above: The Feed. They used to be local to me in Hermosa Beach.
PSA: Pump your tires up on 5/1. I did some dirt/gravel climbing repeats this weekend and being careless, as is my style, I pinch flatted with 60 lbs. in my 32mm GKs on my Nova bike. At 155, I will have at least 75-70 front and rear. And on my Eroica bike with 26mm GKs I had 100psi front and rear with out a problem today on the same gravel climb/descent (other than being a tad freaked out in toe clips and straps while climbing in the loose stuff).
