Substance VR-FB
Vitus
Gravel
Substance VR-FB is an alloy gravel road bike (2023), from Vitus, in the Substance series. This bike is aimed at a wide range of riders thanks to its fit flexibility, with a balanced riding position, while being ready for gravel routes as well as pavement. Its profile is strongest in areas like strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and all-round climbing capability rather than a narrow specialty. 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.
