The set is rounded out by a Selle San Marco Shortfit 2.0 Carbon FX Open-Fit saddle and high-quality Schwalbe G-One RS Performance TLE 45-622 tubeless-ready gravel tires, including tubeless sealant. Of course, the package also includes the SRAM AXS battery with a USB-C charger, the matching DUB T47 Road Wide bottom bracket, and all the brake lines, small parts, and installation hardware needed for assembly.
