I had a bike with a full chorus groupo these came from. I tried them when I hurt my ankle and had issues with my Ultegras. I also tried some other old skool pedals, to no avail. As my ankle healed (again, BB high ankle sprain from decades ago) the Ultegras worked better again. The cleats have been used on maybe 5 rides, so the walking on them wear is superficial. $40 OBO, should outlast the human race, lol, not that that is a big deal anymore, what won't outlast the human race by now?
