Gravel
Planet X London Road Shimano GRX RX810 is an alloy gravel road bike (2024), by Planetx, in the Planet series. It suits a wide range of riders thanks to its fit flexibility, leaning toward a balanced riding position, with a surface profile that is a good fit for mixed paved-road conditions. On MatchBikes metrics, it scores well for strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and less emphasis on aero shaping than on comfort or versatility. That said, what it gives up slightly is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds. If this looks close to what you want, compare this bike on MatchBikes.com against similar models.
