teams have adopted fluid, or shared team leadership at the Tour de France and the other Grand Tours. The 2017, 2018, and 2019 editions of the Tour de France all saw Sky – in 2019, changing sponsorship to become known as – successfully capture the yellow jersey, while a second rider from the team finished elsewhere within the top four: 2017 saw Froome win, with Mikel Landa coming fourth; in 2018, Geraint Thomas won his first Tour de France, while Froome finished third; and in 2019, Egan Bernal, who had himself served as a super-domestique to Froome and Thomas the previous year, subsequently finished first himself, with Thomas finishing second. This top-heavy strategy has also been a feature of other teams in contention, with mixed results. The for the 2018 and 2019 Tour's saw the deployment of the so-called 'Trident' of Mikel Landa, who had moved from Sky for the 2018 season, alongside long-term Movistar leaders and general classification contenders Nairo Quintana and Alejandro Valverde. This tactic was largely unsuccessful for Movistar, who experienced difficulties in coordinating their three leaders, none of whom appeared willing to sacrifice their own ambitions to serve as super-domestiques for one of the other two. Comparatively, a more successful and more hierarchical example of the super-domestique system featured at the 2020 Tour de France through having entered the Tour with shared leadership between Tom Dumoulin and Primož Roglič – both of whom were previous Grand Tour winners, alongside high finishes at the Tour de France itself – Dumoulin recognised that he would be unable to maintain his own general classification campaign, and voluntarily assumed a super-domestique role to Roglič. This allowed Jumbo-Visma to operate with similar tactics to those used by Sky/INEOS in previous years, by setting a higher pace throughout difficult climbs, buoyed by the fact that Dumoulin and other Jumbo-Visma support riders such as Sepp Kuss would remain present in breakaways and leaders' groups to protect Roglič, while the weaker support riders surrounding other contenders would be whittled away. However, their defensive tactics had the unforeseen consequence of Jumbo-Visma helping eventual winner and rival Tadej Pogačar of UAE Team Emirates. Nonetheless, the traditional domestique role remains an important one, and a 2020 poll of riders in the professional peloton by cyclingnews.com named Tim Declercq as the best domestique in the world, followed by Luke Rowe, Michael Mørkøv, Andrey Amador, Imanol Erviti, Michael Schär
