With huge carrying capacity via abundant braze-ons, and space for 4 full-size panniers, the Salsa Blackborow GX Eagle fat bike makes those "it sure would be awesome to" expeditions feasible.

  • Features

    • Perfect for long trips when resupplies are few and far between, or when you want to incorporate backcountry skiing, fishing, trailbuilding or camping into your journey
    • 6066-T6 aluminum frame has better strength and fatigue characteristics than 6061 and 7000-series aluminums, allowing for a strong, light frame
    • Rooted in the same established fat-bike geometry as the Mukluk and Beargrease models; even when fully (and sensibly) loaded, the bike feels well balanced
    • 27.5 x 3.8 in. wheel and tire size, with the ability to accommodate multiple other wheel and tire sizes
    • Salsa Kingpin carbon fork features lowrider rack-mounts and dual sets of Three-Pack bosses on each leg to mount bottle cages or Anything Cages (rack, accessories not included)
    • Suspension-fork compatible
    • Full-length internal housing cable routing
    • Frame accommodates internal routing for a dropper post (not included)
    • Rear rack included, with a capacity of 110 lbs. of cargo; can fit up to 4 standard panniers (sold separately)
    • Multiple accessory frame mounts—3 bottle mounts per frame (S/T front, S/T back, D/T) and 2 accessory mounts per frame (D/T bottom side, T/T top side)
    • Salsa EXP series frame packs, top-tube bags and the Anything Cradle (all sold separately) fit the Blackborow straight away
    • Pedals not included; specs and images are subject to change
