Look Ma, No Hands!
I got to give props to Worksman Cycles for their 1/2" x 35mm pedal spacers. I was having troubles with my big old size 13 sneaker's heals hitting the chain stays on my 49 rollfast. These spacers are heavy! Solid stainless steel, not cheap amazon junk at $33 but worked the charm and will not break. I never realized truly how cramped I felt pedaling, now it is totally a much more free feeling. They are a bit funny looking with the pedals sticking out so far but when I motion I can't see it but the more relaxed feeling is real. I ordered another pair for my other 1/2 pedal bike (they do not make 9/16" as all their bikes are 1/2") Next is to find some larger bow pedals, these are eBay cheapies but all I could find easily in brown/chrome.
