General Road
Planet X London Road Shimano 105 R7100 is an alloy general road road bike (2024), from Planetx, in the Planet series. This setup will suit a wide range of riders thanks to its fit flexibility, with a balanced riding position, and is well suited to rougher pavement and broken roads. Based on the metrics, key strengths are strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and a balanced aero profile for mixed road priorities. The trade-off to keep in mind is 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.
