I’ve never tried Speedplay pedals, but I know quite few people who ride, and swear by, them. They’re new, totally redesigned, and Wahoo is promising much greater reliably and durability compared to the original designs. That’s all good, but there’s also an integrated power pedal coming coming “Summer 2021”.
This is a nice video overview, but for those who prefer to read their news DCR also has the skinny.
UPDATE: DCR has a bit more detail around the power meter version.
