Warbird C GRX 820Description Warbird C GRX 820 is designed around the idea that the most comfortable gravel bike is the fastest one. Its carbon frameset, gravel race geometry, and Salsa's Class 5 VRS (vibration reduction system) soak up rocks, ruts, washboard, and more to decrease fatigue as the miles stack up. Cargo mounts on the frame and fork extend how far you can ride without resupply. Shimano GRX 820 components round it all out with a refined ride experience
