Specialized S-Works Epic 9 Ultralight LTD Full Suspension Mountain Bike Description:
The Specialized S-Works Epic 9 Ultralight LTD shows that it is possible to reduce the weight of a full suspension bike to the point where it is rivaling the lightest hardtail mountain bikes and still deliver a very capable bike with the durability to actually be used on the trails. Starting with the FACT 12M full carbon frame and swing arm, the engineers at Specialized replaced the integrated SWAT downtube storage from previous versions of the Epic with a removable SWAT Box and optimized the construction of the bottom bracket, seat tube, and linkages to shave weight where they could while actually improving the stiffness and durability of the front triangle. Leaving no stone unturned, Specialized applied a trick paint job to shave off more weight while still providing protection for the frame. They also refined the geometry to improve the rider’s ability to generate power and to create a balanced riding position. The suspension guru’s then went to work to revise the suspension kinematics to reduce friction throughout the system, which makes it easier for the Ride Dynamics optimized RockShox SIDLuxe Ultimate rear shock to match the buttery smooth suspension travel of the RockShox SID Ultimate suspension fork up front.
An amazing frame and suspension package deserves an equally amazing list of parts, and the S-Works Epic 9 Ultralight LTD does not disappoint. Fast, precise wireless electronic shifting is provided by SRAM’s flagship XX SL Eagle Transmission drivetrain which delivers a broad gear range so the rider has plenty of gearing for any trail. Lightweight Roval World Cup carbon fiber wheels have a combination of proven DT Swiss 180 hub internals (including ceramic bearings) and trick carbon fiber spokes to produce unreal speed and surprising durability, and they are wrapped in Specialized Fast Trak/Air Trak tires for predictable handling, speed, and traction. Exotic Trickstuff Piccola 2-piston hydraulic disc brakes deliver great lever feel, powerful braking, and add a beautiful accent to the handlebars. Speaking of the handlebars, a Roval Control SL integrated cockpit provides a great balance of compliance and stiffness, and finally, a Specialized S-Works Power Evo Mirror Saddle is perched on top of a Bike Yoke Divine SL dropper seatpost that puts the saddle in an optimal position for the given terrain with the simple push of the handlebar mounted remote lever. Combine the amazing frame with those incredible parts, and the result is an absolute rocket ship of a bike that is ready to deliver blisteringly fast lap times.
Features:
- Insanely lightweight carbon fiber full suspension XC mountain bike that delivers the ultimate go-fast suspension design and parts list
- Progressive XC geometry uses lessons learned through decades of biomechanical research, bike fittings, and the feedback from sponsored/professional racers to put the rider in a very powerful and balanced riding position
- Refined kinematics offers significantly less friction for improved efficiency, faster suspension bump response leading to improved capability, and more speed for each watt pushed through the pedals
- Optimizing the bottom bracket, shock linkage design, lighter hardware, and size optimized seattube designs contribute to removing approximately 206 grams off of an already lightweight S-Works specific FACT 12m full carbon frame and rear swingarm
- Trick paint job provides a more industrial appearance and removes as much weight as possible while still protecting the carbon fibers from the elements
- Removing the integrated SWAT downtube storage found in the front triangle of the previous generation further reduces the weight of the bike and adds stiffness to the front triangle for pin-point handling and better durability
- Included SWAT Box 2.0 provides cargo room for nutrition, flat repair material, or other essentials, and when bolted on it lowers the bikes center of gravity for better control and handling
- Attach the SWAT Box 2.0 when heading out for a fun day on the trails with friends, and then remove it on race day to lighten the bike for a competitive edge
- 110mm front and rear suspension travel provides smooth travel that operates independently of pedaling input, perfect for conquering XC/XCO race tracks and marathon endurance races
- SID Ultimate suspension fork is Ride Dynamics tuned, and the 3-position settings are controlled with the TwistLoc remote that simultaneously controls the settings on the front and rear shocks
- RockShox SIDLuxe Ultimate rear shock also has a Ride-Dynamics tune that offers 3 distinct settings: Wide Open for downhill schenanigans, Magic Middle for optimal efficiency and pedaling performance for most conditions, and Sprint-On-Lock for climbing and the sprint to the finish line
- SRAM XX SL transmission drivetrain provides very quick and precise shifts, even under load, and can be connected to SRAM’s AXS app for shifting performance customization and diagnostics
- TRICKSTUFF Piccola 2-piston hydraulic disc brakes paired with 160mm rotors front and rear are exceptionally lightweight and have plenty of modulation and power to control the bike’s speed in any trail and weather conditions
- Roval Control World Cup Carbon wheels combine a wide and shallow rim, trick carbon fiber straight pull spokes, and DT Swiss 180-based hubs to produce incredibly lightweight and fast rolling wheels
- Specialized Fast Trak and Air Trak tires have a supple sidewall and low rolling resistance that delivers confident speed over a variety of terrain
- Roval Control SL Integrated Cockpit combines the stem and handlebar together to produce an optimized balance of stiffness and comfort
- Bike Yoke Divine SL dropper seatpost can be raised for a stable climbing and sprinting platform or lowered via the handlebar remote to give the rider room to move around the cockpit when facing a technical trail section
- Premium Specialized S-Works Power EVO Mirror saddle delivers comfort, durability, and plenty of support for those long days in the saddle
