The top of the line SRAM XX1 Type 2.1 rear derailleur features small improvements over the previous model, to give you smooth, precise shifting and ultra-reliable performance with your SRAM 1x11 drivetrain. With its "horizontal parallelogram" design and pulley offset, the SRAM XX1 Type 2.1 11-speed Rear Derailleur keeps the chain gap constant across all 11 gears, providing fast, precise shifts. By limiting all movement to the horizontal axis, this design is faster, reduces shift force and eliminates ghost shifting. Roller Bearing Clutch technology reduces bounce and chain slap, while Cage Lock technology makes wheel removal and installation easier than ever before. Paired with the XX1 shifter, the X-Horizon rear derailleur forms the backbone of X-Actuation technology for unbelievably smooth shifting action.

Campagnolo Chorus HO 11 Speed Road Rear DerailleurCampagnolo's Chorus HO Rear Mech features a carbon fibre outer plate and jockey wheel cage and offers you shifting performance that's comparable to their higher spec Record and Super Record models. One of the stand-out features is the “Embrace” technology, which ensures an ultra-efficient chain and cassette interface, secure chain grip, increased durability, and excellent power transfer.Disc Brake Frame SpecificThis HO (hydraulically optimised) version is specifically designed for use on disc brake frames that feature the wider 12x142mm rear dropout spacing. It features an adapted mounting link for easier thru axle removal and larger teeth on the upper pulley for precise shifting at more extreme chainlines.Features: Material: Anodised Forged Aluminium (upper body) Carbon Fibre (outer plate and jockey wheel cage) Multi-shifting technology allows you to upshift up to 3 gears at a time Embrace technology for better drivetrain efficiency Parallelogram with 11x geometry Lightened special rubber pulleysMaximum Cassette Capacity: 11-29T (short cage), 11-32T (medium cage) Weight: 183g Technologies:Ultra-Shift: This control system by Campagnolo is regarded by everyone as the fastest and most precise out there. With this system, you can move the chain simultaneously up 3 sprockets and then 5 down. Furthermore, the lever design allows for an ever lighter shifting, whilst maintaining the "click" sound featured on all Campagnolo controls.Embrace Technology: This technology increases the number of sprocket teeth wrapped by the chain, allowing smooth, fast, and prompt shifting. Proven to optimise the functionality of the rear derailleur even when using extreme cassettes such as 11-32T.

The Campagnolo Chorus EPS groupset takes a great deal of its DNA from its mechanical counterpart as it represents a more accessible version of Campagnolo performance, quality and attention to detail but delivers it in the laser-like precision package of an EPS drivetrain. The shifting performance of the Chorus EPS groupset is exactly the same as its lighter weight siblings, Record and Super Record, making for a transmission fit for professional racing. Shifting even under heavy load is no problem for the Chorus EPS transmission and mud, grime and debris have met their match against such powerful motors. The EPS rear derailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a derailleur rod/parallelogram/derailleur cage, of a worm screw enabled by an electronic actuator. As with the derailleur, the electronic rear derailleur actuator is composed of a gear motor and a sensor, the built-in resolver, that reads its movements. The geometry of the parallelogram has been made more rigid and optimised to promote interaction with the electronic parts. The rear derailleur is also equipped with a play recovery system using a helicoidal spring that optimises stability and precision and keeps operation and performance constant over time, even after many kms have been covered. As with the mechanical rear derailleur, it is possible to optimise its position with respect to the frame and chain by acting on two adjusting screws: the screw that adjusts the mechanical end stop and the screw that adjusts the distance between the upper pulley and sprockets. By using these screws it is possible to optimise the installation of the rear derailleur and increase the precision of its operation. DTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operation. Multi-Shifting There are no longer any limits to multi-shifting and the choice is at the fingertips of the cyclist. Ride back home The uncoupling mechanism of the rear derailleur is useful if the battery runs out ""on the road"", allowing you to manually ""uncouple"" the rear derailleur to position it on which ever sprocket you require. Waterproof In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes.

Redefine Your Comfort Zone. To make a DH-certified full face with the ventilation and fit of a half shell our development team took a fully integrated approach when creating the Gambit. Every component was engineered utilizing a comprehensive approach resulting in truly breakthrough performance where the Gambit delivers more than the sum of its parts. Combines a lightweight carbon fiber shell structurally specific polycarbonate backing and five optimized pieces of targeted density foam (patent pending) for reduced weight optimized fit and increased ventilation. ASTM DH (1952) certified. Tune a more precise personalized fit thanks to Gambit’s adjustable Integrated Fit System that accommodates variations in head shape and occipital base. Occipital base adjustment personalizes fit for comfort and allows you to tune helmet angle to ensure that your helmet and eyewear stay perfectly synched. 4-position adjustable cheek pads provide fit refinement for any head shape. Integrated fixed visor with a breakaway feature provides a wide field of view while protecting against trail debris. Average weight: 640 grams (medium). Increased airflow and improved ventilation from the SBC Integrated Fit System does away with the excessive padding of a traditional full-face friction fit. MIPS SL with our exclusive perforated backing integrates MIPS technology within the helmet padding and reduces moisture retention while increasing breathability. Computational Fluid Dynamic design integrates the maximum volume of internal channeling for optimal airflow through the helmet. 4D brow cooling provides a gap between the helmet and forehead drawing airflow into internal air channels at every speed. This helmet is ANGi ready with a fit system mount designed for easy integration with our ANGi crash sensor.
