Box Two-Three Prime 9 X Wide MTB GroupsetAll set for hitting your favourite local trails, this groupset is available as a Single Shift option for electric mountain bikes (E-MTB) and a Multi Shift option for mountain bikes (MTB). Combining four trail-ready components from Box's Two and Three range, this model is simple to set up and allows you to upgrade your existing drivetrain for functional and intuitive shifting performance wherever your next adventure takes you.Did you know that you can mix and match Prime 9? Can't decide between the modern basics of Box Three and the long service life of Box Two? Well, you don't need to! With this pre-configured and pre-tested option, you'll receive a Box Three cassette paired to the durable Box Two derailleur, shifter and chain.Box Three Prime 9 Cassette 11-50TThe Box Three cassette draws from both of its Box One and Box Two siblings to create a sensible all-rounder. All cogs are stamped from steel. The main difference here versus Box Two is the use of additional weight-reducing holes on the cogs. This X-Wide version offers an 11-50T range.Features: Material: Aluminium, Cold Rolled Steel Finish: ED Black Gear Ratio: 11-50T Gears: 11 - 13 - 15 - 18 - 22 - 28 - 34 - 42 - 50 Box Component's Best All-Rounder Cassette Steel Stamped Cogs Ultra-Wide Ratio with Consistent Progression Prime 9 Technology Compatible with HG Freehub Bodies Weight: 660gBox Two Prime 9 Chain 126LThe Box Two chain's nickel plating adds both corrosion and wear-resistance. All Prime 9 chains have chamfered shifting edges, solid plates and solid pins to safeguard durability. The unique inner link spacing is engineered to grab those modern wide/narrow chainrings. Box chose to modernise the 9-speed platform due to the chain's spirited reputation.Features: Material: Hardened Alloy Steel Finish: Nickel Box Component's Most Durable Chain Nickel Plated Protection Durable Hardened Solid Pins Wide/Narrow Chainring Compatible Compatible with most 10,11, & 12-speed wide / narrow chain rings Prime 9 Technology Weight: 305gBox Two Prime 9 Shifter (Select Option)The Box Two shifter is the only shifter on the market (other than the Box One) that comes factory stock with a hinged clamp. Box Two is performance tier, so this shifter still maintains the durable cast aluminium 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. Available as a multi-shift option (pull several gears at once) or single-shift shifter option (a sound choice for e-bikes). Please select the option from the menu to suit your bike.Features: Material: Glass Fibre / Nylon Composite, Steel, Aluminium Alloy Finish: Matte Onyx Hinged and Extruded Clamp 2 pc Pull Lever / Up to 3 Gears Per Shift* (Multi Shift Option) Die Cast Top Shell Fast Action Release Lever Prime 9 Technology Multi Shift Option Not Intended for E-Bike Use Single Shift Option Recommended for E-Bike Use Weight: 135gBox Two Prime 9 X-Wide Rear DerailleurThe Box Two Prime 9 Rear Derailleur is very similar to the Box One version however, to be more wallet-friendly, it offers a nonadjustable Tri-Pack Clutch, bushing pulleys and some muted finishes.
