Rowing had the sliding rigger boat which was banned in international competition within a year of first being used.

(In a normal racing rowing boat, the athlete sits on a sliding seat, while their shoes and the rigger with the oarlock are fixed to the boat. In the 1980s, boats were developed that had the shoes and rigger as a unit that slid, while the seat was fixed, which was more efficient as it meant that the boat hull and the athlete's mass moved together.)

On the other hand, first carbon-fibre oar shafts and later asymmetrical "hatchet" oar blades were adopted near-universally within a few years of their invention.
