Review on 🚴 THINVIK Clipless Pedal Adapters for Shimano SPD-SL System Pedals - Universal Platform Converters for Road Bikes by Will Schimmel

I have Shimano SPD-SL road pedals - PD-R550 (black) on my e-bike and Shimano 6800 Ultegra clipless pedals on my road bike, both SPD-SL pedals. These Thinvik SPD-SL adapters are not compatible with Ultegra pedals. At least they came close to the PD-R550, but I pushed hard and couldn't get them to hook. If I pushed really, really, really hard I might be able to push them into the pedals, but I was afraid to push harder, afraid I'd literally never get them out. It's too late to bring back those pedals. but I ended up buying an Acacia Bike Pedal Clip Platform Adapter for Shimano SPD LOOK KEO (SPD, NOEMAL) contactless pedals. Acacia adapters fit perfectly on both pedals and require enough force to get out of both pedals. Acacia adapters are the winners. Those Thinvik adapters are useless.
