Scrod, I'm so sorry, that's terrible news. My thoughts are with his friends and family.
Today I am investigating the possibility of putting my
platform/clipless combo pedals on my SS and putting
regular clipless pedals that I already own on the commuter/touring bike. But that leaves me with no foot retention when I wear street shoes on the SS and no foot retention makes me sad. And I wear street shoes on that bike a lot. Hmmm.
