A winning machine for everyone? With the Specialized Gravity Team, the new S-Works Demo 11 has already banked a stack of World Cup results in downhill. Its technical arsenal, headlined by the HighGear drivetrain and the OBB suspension linkage, is Specialized's attempt to rewrite what a downhill race bike can be. The thoroughbred is finally available to everyone, and we headed out to test what it delivers on the trail. **Specialized S-Works Demo 11** | 7.9 inches (f/r) | 29"/27.5" | approx. 42.1 lbs in size S5 | $13,499 | Manufacturer's website Five years in the making, the new Specialized Demo 11 is finally reaching the public. Loïc Bruni, Finn Iles, and Jordan Williams have spent seasons testing it on World Cup tracks around the world, and that work has now filtered down into the production bike. It runs 7.9 inches of travel front and rear and a mullet setup, a 29-inch front wheel paired with a smaller 27.5-inch rear, and tips the scales at 42.1 lbs in size S5. The HighGear drivetrain and the new OBB rear suspension headline the rest, though more on those shortly. All this bike comes at a serious price. For now it is offered only in the S-Works build at $13,499, with the frameset alone commanding $7,999. But must you be racing the clock to have a ridiculous amount of fun aboard it? ### Exciting Facts About the New Specialized Demo 11 **Highs** - High-gear system - Highly adjustable thanks to flip chip and reach adjustment - Premium paint finish and looks **Lows** - High price **Key Facts** - Full-carbon frame - 7.9 inches travel (f/r) - OBB suspension - 3 sizes (S3 to S5) - 42.1 lbs in size S5 ### The New Specialized Demo 11 in Detail Unlike the version Specialized tested extensively on the World Cup circuit, whose machined aluminum lugs and carbon tubes gave it a distinctly Atherton-like look, the production Demo arrives with a conventional monocoque carbon frame. The frame shape and paintwork catch the eye immediately. Organic lines are set off by an elaborate lavender and purple marbled finish called Satin Powder Indigo, with a more understated black and grey marbled option alongside it. The premium paint finish of the new S-Works Demo 11 is a real eye-catcher. The shock sits low in the frame, which is meant to ensure a low center of gravity. The chainstay protector is generously sized to keep chain slap at bay, and the frame features integrated bump stops to prevent the fork crown from hitting the downtube in a crash. ### HighGear Drivetrain: A Game-Changer? One of the most talked-about features is the HighGear drivetrain. It's a sealed gearbox system that replaces the traditional derailleur and cassette, offering a cleaner look and potentially less maintenance. The system uses a belt drive and a 7-speed internal hub, which Specialized claims provides a wider gear range and faster shifts. We found it to be smooth and quiet on the trail, though it does take some getting used to if you're coming from a conventional setup. ### OBB Suspension: What's the Big Deal? The new OBB (Optimized Balance Beam) rear suspension is designed to keep the bike balanced under braking and pedaling. It uses a linkage-driven single pivot with a floating shock, which Specialized says improves traction and reduces pedal kickback. On the trail, the suspension felt plush and bottomless, soaking up big hits while remaining active under braking. It's a marked improvement over the previous Demo's suspension design. ### Who Is This Bike For? At $13,499, the S-Works Demo 11 is undoubtedly a boutique race bike aimed at those with deep pockets and a need for speed. But is it for everyone? If you're a privateer racer looking for every advantage, or a well-heeled enthusiast who wants the best of the best, the Demo 11 delivers. However, if you're on a budget, the frameset at $7,999 might be a more attainable route to building your dream downhill rig. In the end, the S-Works Demo 11 is a testament to Specialized's commitment to pushing the boundaries of downhill technology. It's a race bike at heart, but one that offers a ridiculous amount of fun for anyone lucky enough to swing a leg over it.
