I know they exist. I have seen them in the corners of the internet, but they don't seem to be as prominent for traveling over seas for cycling. I prefer SPD style petals to go touring and cycling in general. Touring shoes, which basically snap into the bike gives me twice as much power going into a session. However, shoving my bike into the suitcase and needing to unscrew them carefully so that I don't strip the teeth on my crankset. I have nightmare of stripping them on a road side or just before a tour and screwing myself because taking things apart and putting them back together for a ride bothers me. So, I see these SPD clip in petals that are quick release and you can easily click them into place from storage to on the go. It's thoughtful, but so far I never hear any review on these spd quick release petals. How do they fair? Are they worth it? Are they cheeply made? Retailers are usually chinese, which tells me that they aren as in demand globally for the cycling traveler. Obviously, the flat petals are easy to find with quick release, but this is something that has been raking my brain, whether to trust this and go out of my way to get them or stick to my old spd petals and hope an unfulfilled technical nightmare
