Experience incredible steering precision, small bump sensitivity, and absolute control with the new Onyx 38. A unique E-Designed chassis, wider-than-ever stance, and burly 38mm stanchions launch the Onyx into a new era of MTB Suspension. All new demands require all new thinking. The Onyx D1 38 sets a new standard in E-Designed suspension. What does it mean to be specifically E-Designed? For years, the market has taken “acoustic” suspension and made after-thought upgrades in order to make it “E-Bike Approved”. Bumping up compression damping, using a slightly thicker crown, or just saying “Add 10 PSI” isn’t doing it right. E-Specific design means we thought about these needs from day one. How can we make a fork flex equally as one unit? How can we achieve unreal steering precision without the harshness or deflection? How can we control the fore and aft flex issues the added weight of an e-bike puts on a fork? Questions like these were the foundation, the bones of this concept. After years of engineering, different thinking, and countless hours testing, we nailed it. The final result wasn’t only a fork that met all the requirements and needs of a modern, aggressive E-bike, but it directly translated to a regular bike. NOT ONLY IS THIS THE PINNACLE OF E-BIKE SUSPENSION, IT’S THE NEW STANDARD FOR SUSPENSION. - Burly fork designed for the rigors of E-Bike use, providing steering precision without harshness or deflection - OTT (Off The Top) is an adjustable coil negative spring that allows the rider to dial in initial compliance without affecting the mid and end stroke - The D1 damper features updated high-flow compression and rebound porting to allow a linear suspension dynamic. This initial damping support without any high-speed harshness paired with a 30% increased volume in the Compression Bladder System results in increased small bump sensitivity and damping consistency - High flow linear rebound update increases response without a loss of control or damping - A purpose-built crown increases drop for extra down tube clearance and features a dual hollow bore design with strategically varied wall-thickness for improved stiffness and strength

Ready For Rowdy The little brother to the Onyx DC, this is the Onyx SC D1. At 180mm of travel, this is our top-of-the-line enduro race fork. Featuring the proven D1 damper, high/low-speed compression, rebound, and externally adjustable OTT. With 36mm stanchions and our stiffest chassis yet, charge hard into the roughest sections with confidence. Six clicks of low-speed compression give quick access to firming up the fork for pedaling, opening up for descending, and mid settings for everything in between. Over thirty clicks of High-Speed Compression give precise control for support on big hits. Shim stack controlled rebound that is 100% dynamic. meaning, the rebound is controlled based on the speed at which oil flows through the system. The fork will react to what you throw at it and be ready for what's next. Our industry-exclusive OTT feature really sets DVO products apart from anything else. It allows you to perfectly fine-tune how the initial stroke feels without any mid/end stroke compromise. You really do the best of both worlds. Combining the stiff chassis characteristics with our exclusive features and damping design gives our forks a unique ride feel unlike anything else on the market. - D1 Damper - Compression Bladder - OTT Off the Top Adjuster - Shim Stack Controlled Damping

The new Super Record 12x2 Speed crankset: an intense concentration of innovation that results in the greatest possible stiffness and precision in derailing, whilst providing a dedicated aerodynamic “super design." The new carbon fiber Super Record 12x2 Speed crankset has been made lighter on the inside through Campagnolo Hollow Technology, which uses the Ultra-Torque bracket system with a titanium axle to transfer all of the force the athlete applies to the pedal to the drivetrain. The new Super Record 12x2 Speed crankset can be installed on any type of frame, whether or not it is being used with disc brakes because it optimizes the chain line on the frame with a rear hub flange measuring 130, 135 or 142 millimeters, without affecting the Q factor, which remains constant at 145.5 millimeters thanks to the new hand crank design. The use of ceramic Cult bearings leads to obtaining the smooth ride that the Campagnolo brand is known for. The innovative design of the outer chainring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chainring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimeters) combined with the eight fixing screws, optimize weight and stiffness through the increased use of carbon fiber. The varying number of pins for each of the three chainring combinations (34/50, 36/52, 39/53) facilitates upshifting due to the optimized free strokes associated with each combination. The special drains on the inside of the outer chainrings optimize performance when downshifting in dead spots.
