Salsa Tributary C GRX 820 Description:

The Salsa Tributary C GRX 820 is the best option for riders planning on long scenic routes connected by rugged, unpredictable terrain, by providing a lightweight carbon frame, dotted with ample cargo options, and the intelligent design of Bosch’s Performance mid-drive E-Bike assist system for a rugged-road adventure bike that’s ready to take riders from their front door to far-out. Tributary C carbon frames inherently reduce vibration and reduce weight through a custom-tuned blend of stiffness and compliance; Tributary C incorporates Salsa’s Class-5 VRS seat stays, increasing comfort by allowing more outward flex on impact, while maintaining efficiency. Bosch’s Performance Line Class 3 motor delivers loads of torque and range, and keeps the motor’s weight low and centered on the bike for neutral handling that complements Tributary’s gravel geometry, adding comfort and control in even the most unpredictable of conditions. Bosch’s PowerTube 625 battery offers enough range to get lost on your favorite forest roads and is fully encased in the downtube for added stiffness and a nice, clean look. The minimalist Bosch BRC3100 system top-tube controller displays assist mode and battery charge level, letting users quickly choose an assist mode — all without cluttering the cockpit.

Clearance for up to a 29 x 2.6” tire (29 x 2.4” with fenders) enables the traction and compliance of larger tires on rugged roads at the higher speeds E-Bikes allow. Tributary fits two bottles inside the frame on all sizes and offers plenty of frame bag space; users looking to take on even longer hauls can employ the dual Three-pack mounts found on Tributary’s fork for additional hydration, direct mount packs, or any other handy bikepacking cargo accessory. Rack and fender compatibility for both the front and rear keeps Tributary C at the front of the line for your next bikepacking adventure, or at the very least your go-to year-round commuter. Salsa Tributary C rides and hauls expertly, and thanks to Shimano’s GRX 1 x 12-speed mechanical drivetrain, users will experience consistent, gravel-focused shifting that affords a versatile range for every descent and climb.
