For those with Serious issues. The all-new F-Si.


Obsessives unite. We’re constantly striving to go faster and perform better. That’s what we humans do. We push everything. But when it comes to today’s XC, this is especially true. XC riders put an unbelievable and unprecedented amount of focus, discipline and training into their pursuit, and they’ll do anything to get an edge. And with how heavy courses are these days, they need more edge than ever. Steep. Rough. Full of lung-busting climbs, angry rock gardens, jumps, even drops. Leaving XC crazies in need of a bike that can climb like a homesick angel, and descend like the devil himself. A bike with power and precision. With prowess and agility. To take them as far as their obsessions demand.


Meet the ultimate race hardtail. For those with Serious issues. When the original F-Si hit back in 2015, it changed the game. Pushed the limits. Changed peoples’ idea of what an XC hardtail could do. Well, surprise, surprise…the new F-Si is even F-Si-ier. It’s even lighter - the lightest MTB frame we’ve ever made. Shorter Ai™ chainstays for more traction and kick on the climbs. Slacker head angle for even more OutFront™ control when things get dicey on descents. Improved stack and reach numbers for amore optimized rider position. Precise compliance tuning throughout the frame for more comfort, seated or standing, all while still having power transfer you need for full-gas efforts. And of course, leading things off, the stunning new Lefty Ocho. It’s a whole new level of XC capability, tailor made to feed the needs of the XC obsessed.


Lefty Ocho OutFront. The all-new Lefty Ocho rewrites the book on XC performance. The smoothest, stiffest ultra-light XC fork ever made, it floats through chop and steers through the choss like nothing else. Silky smooth and unfazed no matter how hard you push it. Happy to get in as deep as you dare. Its extra-long fork offset pairs up with the F-Si’s new, slacker 69° head angle to create OutFront geometry, giving you extra stability to charge the downs, with full XC agility on the ups. Helping the F-Si track perfectly through whatever you throw it into.

Ai party in the back. Short chainstays do wonders for traction and nimble handling, but they usually come at a cost. Ya gotta give something to get something. Not so with Ai. Ai is our proprietary Asymmetric Integration drivetrain offset. By moving the gears and rear triangle over 6mm, we double the amount of space that boost provides. This enables us to shorten the stays AND still have clearance for big tires and room for 2x drivetrains if you want. It even creates a stiffer, stronger rear wheel by evening out the dish. Smart, right?


The machine to match your obsession.


A deeper look at the details. BallisTec Carbon

Hidden seatpost collar

Our proprietary BallisTec Carbon construction lets us push boundaries and tune rigidity throughout the entire frame – for stiffness where you need it and compliance where you don’t. With so much durability, we back it with a lifetime warranty.

For seated comfort, designing the F-Si with a 27.2mm seat post was just the start. Our collarless seat post clamp takes it even further, lowering the clamping point so that more of the post can flex. Put the power down all day long, without the punishment.

SAVE Micro-Suspension

Speed Release Thru-Axle

SAVE Micro-Suspension tunes the overall compliance of the frame. Rear triangle flexes vertically for shock absorption. Directionally optimized carbon layup in the seat tube allows controlled fore/aft bowing. Better traction, higher speeds and drastically minimized fatigue, whether seated or standing. Go faster longer.

A faster kind of thru-axle. Slotted dropout design lets the axle stay in the hub for quicker, easier wheel changes. Compatible with standard 148x12 hubs. It’s a better way thru.
