I get the impression that Ineos/Sir Jim Ratcliffe are less bothered about the team being British than Sky/Sir Dave Brailsford were. So, okay, he bought a British-registered cycling team and is sponsoring the British effort in sailing. But on the other hand, he owns Swiss and French football teams and sponsored the marathon world record attempt by a Kenyan. I would go so far as to say that if Sir Dave left, it's doubtful that a new regime would really care about British riders. Sure, they'd probably want to keep Rowe, Hart and the incoming Pidcock, but they'd want them just the same if they were from Malta. I don't think Ineos is necessarily going to be a long-term pathway for British riders in the future.
If you look at their best climbers, the top 5 or even 7 are probably all non-British except maybe Thomas is borderline and he's getting old, and maybe Hart just about squeaks in there. So I don't see how post-Sky Ineos is really responsible for making the United Kingdom a cycling superpower. So far their contribution to British cycling is for Chris Lawless (booted out of the team for next season) to win the much-watched Tour de Yorkshire, Owain Doull to win a super prestigious stage of the Tour de la Provence, Ethan Hayter to win the mighty Giro dell'Appennino and Tao Hart to fluke (until further notice) a Giro.
I would argue that their contribution to Colombian, Ecuadorian and maybe even Italian and Russian cycling, is more valuable than their contribution to British cycling has been since May 2019. Their contribution will be smaller again next year as they lose three Brits and only bring two in. I could argue even more audaciously that there was (maybe is) a gap in the market for a new, British-focused team in 2019 or 2020, with Froome, Carthy, Hart, Yatesx2 and Pidcock as the stars, and let Ineos focus on South American riders.
