Gravel bike to complement a decent road bike and 29” MTB in the UK - Yorkshire

Should mention the bike really but it doesn’t tick all your boxes but maybe a wild card.

Fairlight Faran 2.5 (partner has the also great Secan). This sits between my carbon weight weenie road bike and XC hardtail. It is somewhat utilitarian but the longer I own, the more I love it.

With chunky mezcals, it is supremely confident off-road and the current iteration (v3.0) allows for 180mm rotors to really push into mtb terrain. Front loaded, it is so confident and was fantastic descending some alpine roads recently.
