Salsa Bucksaw Full Suspension Fat Bike Squishes Into Reality
Is it just us, or are we getting fat today? After seeing new (front) suspension ready bikes from Borealis and Rocky Mountain, both using the new Rockshox Bluto, Salsa cannonballs the party with the new full suspension Bucksaw.
And it’s not just a simple full susser. It takes the Split Pivot suspension design of their 29er mountain bikes, spreads the frame to handle up to 3.8″ tires and adds a custom tuned Rockshox Monarch shock to give it 100mm of supple, bump eating performance. Couple that with a 100mm Bruto up front, and you have the world’s first real production full suspension fat bike.
Look past the oversized balloons it’s riding on and you’d be hard pressed to tell the spec from any other mid- to high end bike…
The frames are 6066-T6 double and tripled butted heat treated alloy. Tubes are shaped, with a tapered head tube and oversized down tube for stiffness. In the back, it’s lightened up with carbon fiber seatstays. It’s laid out for full length cable housing, and there’s even routing for a stealth dropper seatpost and ISCG05 tabs.
Rear hub spacing is 177mm with frame spacing maxed out by a 3.8″ tire and 82mm wide rims. BB is Pressfit 41 (121mm, same as their Beargrease hardtail fat bike) and the front triangle has room for a water bottle.
Two models will be offered at launch, both with the new SRAM Guide brakes and Rockshox Bluto fork. Complete specs are:
Frames come in Small, Medium, Large and XL sizes, all with good stand over clearance.
The prototypes, shown above on the right, used parts modified from their Horsethief and Spearfish 29ers and Maverick DUC32 and Lefty Max forks to prove the concept. They ended up having a lot of fun on them, and after two+ years of testing and development (not to mention the very fortuitous timing of Rockshox’s Bluto launch, they’ve got something new to play on.
