Gravel
Planet X London Road Shimano GRX RX810 is an alloy gravel road bike (2023), by Planetx, from the Planet lineup. This model is best for a wide range of riders thanks to its fit flexibility, with a setup that gives you a balanced riding position, with a surface profile that is a good fit for mixed paved-road conditions. Based on the metrics, key strengths are 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. The trade-off to keep in mind is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds.
