“The main refinements to the pedals include sealed bearings, which Wahoo claims removes the need for regular maintenance; updates to the pedal body which are said to increase durability; and refinement of the spindle sees the removal of wrench flats in favour of hex key adjustment.”
Heavier, but no need to add grease.
They do look more durable to be fair.
Seems like the one to go for is the Speedplay Zero stainless and change to a Ti spindle (like before)
