A versatile bike for all your drop-bar adventures. If you’re looking for 1 bike that you can take bikepacking, and you can use in the local Fondo, the Tambora G4 is your steed. Thanks to a clever bit of engineering, you can swap your Tambora from stability focused gravel geometry to nimble road geometry in only a few minutes. On-road and off, the microSHIFT 1x drivetrain gives you lots of mechanical advantage to smooth out the hills. And Tektro mechanical disc brakes keep your speeds right where you want them.
