Well, actually, I don't know if they were a NAPA shop officially. When in Bend, I broke my Crankbrothers pedal JRA. The spring that holds the wings gave up, so I thought I'd have to buy a new pedal.
Not so. This solution, thanks to an auto repair shop and $1, works great. Sarah and I cam up with it collaboratively (I executed the solution on the trail with zipties from my rear brake line, but they proved not to be strong enough, she suggested a hose clamp). Of course, you only get a single clip-in side, rather than 4, but it's surprisingly easy to get into anyway, since the hose clamp tends to hang straight down and put the good side up.
I was pretty pleased with my cleverness, and it allowed us to ride for the last 2 days of our trip, without buying any new pedals.
