Endurance
Planet X Kaffenback SRAM Rival 1 is a carbon endurance 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. The main strengths in the metrics 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. That said, compared with more specialized alternatives, the compromise 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.
