The Box Two groupset delivers similar performance to the top-tier Box One without the costly features. You still get the Tri-Pack (TM) Clutch in the rear mech only it isn't adjustable. The cassette's 11-50T range is equally impressive and the action on the shifter is just as snappy although you don't get the rigid die-cast pull lever. Completing this groupset is its high-quality chain, which boasts impressive torque power and speed as you explore the trails on your mountain bike. Box Two Prime 9 Shifter The Box Two shifter is the only shifter on the market (other than our Box One) that comes factory stock with a hinged clamp. Box Two is our performance tier so this shifter still maintains the durable cast aluminum top shell but trades out the Box One's 1-piece pull-lever for a 2-piece resin and steel variant. All Prime 9 shifters take advantage of the 9-speed's inherent durability, simplicity, and reliability. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. And the best part is? Prime 9 is also terribly forgiving so you won't have to constantly adjust your set-up.

Chainset Features: Material: Aluminium (chainring), 7000 series Aluminium (crank arm) Bottom Bracket Interface: SRAM DUB Chainline: 49mm Bolts: Direct mount Recommended Chain: SRAM Eagle Compatibility: All Eagle drivetrains Weight: 705g (175mm, 32T ring) SRAM NX Eagle DUB 12-Speed Shifter Despite the NX model falling under the “entry level” category, SRAM has still managed to pack in some of its best technologies. These include ZeroLoss™ and X-Actuation™ technologies, which combine to offer instant shifts and sharp shifting across the full cassette range. Shifter Features: Material: Aluminium/Plastic, Stainless Steel hardware Compatibility: All Eagle drivetrains Matchmaker compatible for dropper remote and brake lever integration Weight: 112g SRAM NX Eagle DUB 12-Speed Rear Derailleur As seen on the top-of-the-line XX1 and X01 models, the NX Eagle rear derailleur also adopts SRAM’s 1x specific X-Horizon™ cage design. This carefully engineered mechanism ensures capacity for the huge 11-50T cassette and compliments the smooth Performance of an Eagle 12 speed system. This derailleur also boasts SRAM’s Type-3 Roller Bearing Clutch™ for unrivalled durability and quiet consistent performance. Features: Material: Aluminium (cage), Steel (spring, pulley), Stainless Steel (hardware) Max Tooth: 50T Compatibility: All Eagle drivetrains Weight: 339g SRAM 12-Speed Chain At the core of all Eagle drivetrains, the 12 speed Eagle chain is designed and manufactured with SRAM’s Eagle™ architecture. This ensures perfect compatibility with all of the other components in any Eagle ecosystem for highly efficient, smooth and quiet shifting that you can take for granted each and every time you hit the trails. Features: Material: Steel Rivet Type: Solid pin Compatibility: All Eagle drivetrains Weight: 278g (126 links) SRAM NX Eagle 12-Speed Cassette SRAM designed its NX Eagle cassette to provide riders with the option of upgrading to 12 speed, but without the need for a hub or wheel upgrade. Ready to fit straight onto standard “splined-drive” freehubs and offering a massive 11-50T range, this cassette gives you the climbing range you need to attack the climbs and the smooth performance to get the most out of your other Eagle components. This cassette is also designed to be durable enough for the extra demands and abuse of E-MTB use. Features: Material: 8 lightweight, stamped steel cogs and 4 high-strength steel cogs pinned onto an aluminium spider Recommended Chain: Eagle chain only Compatibility: All Eagle drivetrains Weight: 615g Technologies: X-Sync 2: X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology. The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-Sync Eagle design reduces friction and the accumulation of mud, grit and grime. DUB Technology: The relationship between the bottom bracket spindle and bearing is the core of DUB™ technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler, by better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance. Zero Loss: The gear cable is engaged instantly with zero loss of movement when you press a shift trigger, every gear change is instant and precise. Matchmaker X Integrated: You can put everything from your XLoc suspension lockout, your SRAM shifters and brake levers as well as your Reverb XLoc remote, all on two clamps. It's the ideal way to put everything within easy reach and tidies up your bike's cockpit. Cage Lock: With Cage Lock technology in the rear derailleur, wheel removal and installation, as well as chain installation, becomes faster and simpler. Just push the cage forward to create slack and lock it into place Roller Bearing Clutch: The Roller Bearing Clutch delivers maximum drivetrain stability even through the most punishing terrain. This stability benefits the drivetrain dramatically, as derailleur bounce and chain slap are eliminated without sacrificing precision X-Actuation: Developed specifically for SRAM 1x drivetrains, X-Actuation keeps shifting sharp and consistent across the entire cassette. This makes gears easy to index and provides exceptional performance. X-Horizon: The X-Horizon ‘straight parallelogram' design limits all movement on the horizontal axis, which makes ghost shifting impossible while also reducing shift force. The large upper pulley offset design maintains a constant chain gap across all gears and guarantees faster and more exact shifting. Flow Link: Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile and a flatter outer plate that can withstand greater shifting angles. This means more consistent chain riveting and enhanced overall strength is achieved. PowerLock: SRAM chain engineers developed PowerLock as a tool-free and consistent way to connect mountain bike chains. While PowerLock does not require special tools for installation, the especially tight tolerances of 10, 11 and 12-Speed drivetrains mandate that each PowerLock is good for a one-time application only. X-Glide 2: This optimised cassette technology, which has been custom designed for the Eagle drivetrain is the next generation of X-Glide shifting. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.

With its new design as well as a plethora of useful and innovative new technologies, this small component improves the EPS experience in a big way. Improved integration, facilitated and nofuss charging, improved led diagnostics and wireless technology that allows for increased interaction with the groupset are just a few of the improvements housed in its tiny structure. Enclosed and protected in the Power Unit and interface, ""Digital Tech Intelligence"" transmits, receives and processes data thousands of times a second. An electronic brain which instantaneously synchronises all the functions requested by the rider. With just a simple click of the controls, D.T.I transmits the corresponding signal instantly, accurately and reliably to the rear or front derailleur, for levels of performance and control feel never experienced before with a conventional drivetrain. But as well as all this, the D.T.I. system also monitors the entire drivetrain and each of its components, continuously checking battery level and functionality, and checking that the rear and front derailleur are working correctly. The procedures to reset the rear derailleur and derailleur to zero are essential for the system to function.These procedures allow the system to learn the reference positions of the chain on the sprockets and chainrings, which will be used to calculate the positions that need to be used in all operating conditions. During the resetting to zero phase the movements of the rear derailleur and derailleur occur continuously, and not through set movements as during adjustment, and they depend on the pressure time of levers 2 and 3. The client can adjust the reference position of the rear derailleur and/or derailleur using the adjustment procedure known as Riding Setting. The adjustment of the rear derailleur is designed especially in case you change the wheel for one with a set of sprockets that are positioned differently with respect to the drop out.It is possible to start the procedure for either the rear derailleur or the derailleur from any chainring. Every time either keys 2 or 3 is pressed, the system performs a set displacement of 0.25 mm if you act on the rear derailleur, and approximately 0.1 mm if you act on the derailleur. When you have completed the adjustment phase, the system will correct the established positions of all chainrings based on the new settings. The EPS system is capable of automatically detecting a whole range of malfunctions.If a malfunction is detected, the EPS system turns on an RGB led located on the power unit. Depending on the area where the malfunction has been detected the led takes on different colours, as per the table below. Being that in some situations the cause of the malfunction making the led light up on the power unit may be temporary, a number of operations are recommended to the end user depending on the colour of the light that appears on the PowerUnit."

Excellent sealing and reliability have been proven through repeated field tests in various riding conditions, including extreme temperatures, rain, mud, and cobble stone roads. Using a hard wired battery system which is both light weight and accurate compared to current wireless technology (as a wireless system would require 4 batteries: one for the RD, one for the FD, and one for each shift lever). The use of a single small and discreet battery is light weight, efficient and creates a robust and reliable system. One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain).
This unit easily plugs into Shimano’s E-tube wiring system and is powered by the same battery that powers the Di2 system. Connect and Monitor This unit offers both ANT+ connection and Bluetooth connection, so it can connect to compatible cycle computers to enable you to monitor gear position, battery life, and other rider data functions. Mechanics can use the e-Tube Project wireless app to connect via a tablet or smartphone to change shifting preferences to suit the rider or the type of road/terrain.
