Ritchey's history with cyclocross runs long and deep, sort of like the mud sections of your favorite 'cross course. The WCS Carbon Cross Disc Fork is designed from the ground up to manage the unique stresses a disc brake demands – including a carbon layup that resists twisting under hard braking. Decades of experience between the course tape, and building the bikes and components designed to win, inform the performance and design details of this fork. It employs a monocoque construction, it's compatible with standard and integrated headsets, and features carbon dropouts and disc mount. - Blade: Carbon - Crown: Carbon - Steerer: Carbon - Steerer Length: 300mm - Steerer Diameter: Tapered 1-1/8 – 1.5-inch - Rake: 45mm - Blade Shape: Curved - Drop out: Carbon - Rotor size: 140mm (160 w/ adapter) - Crown Diameter: 45mm - Integrated 45-degree crown race - Axle-to-Crown: 395mm - Finish: Matte UD carbon - Weight: 440g (w/ uncut steerer) - Compression plug included

The new Record 12x2 Speed crankset: a new hole-free design for the right-hand crank that optimizes aerodynamics. The new carbon fiber Record 12x2 Speed crankset with unidirectional finishing guarantees continuity with the finishing of the entire groupset, whilst maintaining the Ultra-Torque bracket system on the steel axle to ensure perfect transmission of power. The new 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 that remains constant at 145.5 millimeters. 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) enable reducing the weight through greater use of carbon fiber. There are eight fixing screws for increased structural stiffness. 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.

The new mechanical Ergopower Super Record 12x2 Speed Rim Brake controls ergonomics, comfort, control, precision. The new mechanical Ergopower Super Record 12x2 Speed Rim Brake controls offer an important new feature: two brake lever positions that allow riders to choose the lever-handlebar distance that is most suited to the size of their hand. It does so whilst keeping braking efficiency constant the new angle of the up-shifting lever that prevents any possible contact with the curve of the handlebar. The position of the lever is adjusted by acting directly on the controls in a simple and safe manner. The Vari-Cushion technology offers ergonomic, comfortable and safe support and grip, ideal for riders who are in the saddle for many hours. The internals of the controls boast a concentration of technologies and experience, starting with the “one lever, one action” feature that assigns one function to each lever in order to prevent shifting errors when tired or distracted. This is followed by the option for multiple shifting that enables upshifting up to 3 sprockets at a time and downshifting up to 5 through the Ultra-Shift mechanism. The new Super Record 12x2 Speed Rim Brake levers introduce a double curvature to improve grip, which is lightened by three slots.
