Salsa Tributary 29er: 28mph Class 3 Gravel E-Bike Aluminum Frame

The Tributary Electric Gravel Bike is engineered for riders seeking to conquer rugged trails and remote routes with effortless power and confidence. This Bosch-powered e-bike merges off-road capability with everyday practicality, whether you’re tackling multi-day bikepacking trips or commuting through forested backroads. Its aluminum frame and carbon fork deliver a smooth ride over uneven terrain while accommodating tires up to 45mm wide—ideal for loose gravel or muddy singletracks.

Performance Highlights
– Bosch Performance Line Speed Motor: A class 3 mid-drive system (85Nm torque) boosts your efforts up to 28mph (45km/h), perfect for conquering steep grades or extending your daily mileage.
– 625Wh PowerTube Battery: Hidden within the frame for sleek aesthetics and 72-mile range on a single charge—enough for all-day adventures without recharge stops.
– 4 Assist Levels + 340% Torque Boost: Tailor power output to terrain or fitness goals, from gentle support on smooth paths to maximum assistance on technical climbs.

Build Features
The Tributary’s Shimano GRX RX812 drivetrain pairs with an 11-42T cassette for seamless shifting across varied gradients. Hydraulic disc brakes (Shimano RX400) ensure reliable stopping power in wet or dusty conditions. A dropper seatpost (TranzX YSP18DL) adapts your riding position on-the-fly, while WTB ST wheels wrapped in Teravail Ehline 2.3″ tires grip loose surfaces confidently.

Cargo-Ready Design
Salsa’s integrated mounts support racks and panniers for loaded touring—ideal for packing gear on multi-day trips or hauling groceries home from weekend excursions. The ergonomic drop bars and shock-absorbing grips prioritize all-day comfort during long rides.
