General Road
Planet X London Road Shimano 105 R7100 is an alloy general road road bike (2023), by Planetx, from the Planet lineup. It suits 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 well suited to rougher pavement and broken roads. Standout strengths from the metrics include 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 main trade-off is less emphasis on outright speed than speed-focused builds. Compare this bike on MatchBikes.com to similar general road models.
