Remco is a beast but Logic is underrating Primoz so badly in climbing TT skills based only on Plache de Belles Filles and Slovenian national from 2020 (where Roglic almost beat beat Pog riding the climb with the TT bike wich was a big mistake). Precisely, Primoz is knomw for his ability of pacing himself in hard TTs, he normallys never go full on the flats and then he flies in the climbing part. Example of this is Bergen 2017 when was the fastest in Mount Floyen, First TT of 2019 Giro where he also put the hammer down on San Luca, the second one in San Marino also was another example of Roglic killing even more the field in the last climb after a godd flat part. Then in The Vuelta you have also the Ezaro TT with Primoz doing the difference only there. In 2018 Romadie in Ollon sur Villars pure W/kg fests over 25 minute he started too slow but almost make the comeback in the last part on Egan (in one of the most explosive climbing version of the colombian ever in my opinion) with both doing around 6.7 w/kg at least if i remember correctly, and Roglic has improved a lot in climbing since them.
Then of course you have the Tokyo TT where he was crazy faster than anyone in the second lap climbs. Even we have mini exmaples of this capacity of Roglic in shorts time trials like the Basque Country one where he always delivers a super sonic last hill like in 2021 or 2022 winning there the TTs (but that were only little hills of course).
Monte Lussari is just a different beast in a TT, but also for Remco, so we wil see...
