Specialized S-Works Epic Hardtail Frame
$2,599.99
The S-Works Epic Hardtail is the lightest and most capable carbon hardtail frame ever created. Need we say more? While that does a great job of summing things up, if we're being honest, we're still a bit too proud to leave it at that. An impressive 140 grams lighter than the already "how'd they do that"-light Epic Hardtail frame, the S-Works frame makes use of our FACT 12m carbon to cut a figure that'll make any gram-counter swoon, while still offering riders enough capability and composure to wring out extra seconds on any section of course, not just the groomed bits. Working towards the lightest bike possible has long been the race within the race, but at what cost? The battle of the grams certainly hasn't been without its casualties, with hardtail XC race bikes coming to stand for a harsh, twitchy ride at the expense of capability and versatility. But who said fatigue from fighting against your own bike makes you any faster? Instead, recognizing that the fastest bike is more than simply the lightest bike, we said out with the "jarred-to-death tail", the "measure-your-posterior's-sorrows-by-the-yard tail" and in with the "avant-garde tail". The ridiculously capable, mystifyingly comfortable, head-shakingly light and all-around fast, Epic Hardtail. Sure, we optimized every inch of the Epic Hardtail frame to achieve the lightest production hardtail frame in the world anyway, but we also prioritized our commitment to creating an Epic Hardtail that's as capable as it is comfortable with aggressive singletrack-inspired geometry, increased tire clearance and a frame obsessively engineered for increased vertical compliance, all while creating a bike that lives and breathes the fundamentals of fast. - Ridiculously capable and refreshingly compliant with a weight that'll make most road frames jealous, the FACT 12m carbon S-Works Epic Hardtail frame isn't just light, it's the lightest production hardtail frame ever produced.
Specialized S-Works Stumpjumper Frame
$2,999.99
When we say "The Ultimate Trail Bike," we mean it—the all-new Stumpjumper is everything you could ever ask for in a dirt-shredding steed. Want a bike that climbs with ease? The Stumpjumper delivers, with the help of a ground-up suspension re-design and a lightest-in-class frame weight. How about something that's ready to shred when the trail turns against you? That suspension re-design, paired with new Trail Geometry and a Rider-First Engineered frame that's the perfect blend of stiffness and lightweight, turns the Stumpjumper into an absolute monster descending. Point the front wheel where you want to go and be ready to party. THE TRAIL BENCHMARK When we set out to design the all-new Stumpjumper, we pursued some hefty goals. We went after the lightest-possible weight that sacrifices nothing in terms of durability, a stiff chassis that corners on rails, and a geometry that everyone can enjoy, all with the best suspension kinematics we know how to design. Turns out, you can have your cake and eat it too with the new Stumpjumper. THE SWEETEST 130MM OF TRAVEL YOU'LL EVER RIDE We massaged the kinematics of the Stumpjumper suspension to bring out the very best all-round performance possible in a 130mm package. Countless hours of suspension lab development and field testing created a refined mid-travel ripper that eats big terrain like a gravity fed beast, handles like a dream everywhere, and climbs like it has a motor. PROGRESSIVE GEOMETRY The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. It's long, low and slack, with a short offset fork and a steeper seat tube angle. These numbers combine to make your ride more stable, more carvealicious, more comfortable climbing, more better everywhere. With FlipChip adjustability you're able to further fine-tune your fit, ensuring that your new Stumpjumper performs flawlessly on whatever terrain you choose. RIDER-FIRST ENGINEERED Rider-First Engineered frames use a size-specific approach to ride characteristics that ensures every frame performs flawlessly. So, whether you're a Grom riding an S1, or in need of the lengthy S6, you'll experience the same ride characteristics—on-rail cornering and balanced front and rear stiffness, all at the lightest-possible weight: 2,250 grams (S-Works, Medium, with rear shock). SWAT When we introduced the SWAT door on the Stumpjumper in 2016, we increased pocket space, and added room for those “oh s**t” pumps and flat accessories. With the new Stumpjumper, we've kept those same design hallmarks that you know and love.
