The Box One chain is protected by our dual-coating. We start with Nickel plating which aids in corrosion resistance and then top it off with the "Diamond-Like Carbon" layer. The DLC is as fancy as it sounds; a synthetic diamond nano-coating that turns up the volume on hardness, wear-resistance, and slickness. All Prime 9 chains have chamfered shifting edges, solid plates and solid pins to safeguard durability. Our unique inner link spacing is engineered to grab those modern wide/narrow chainrings. We chose to modernize the 9-speed platform due to the chain's spirited reputation.

All Box headsets are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars, through the stem-to-bar interface, we arrive at the headset focal point. Since any steering stiffness can easily be lost to headset play, we have concentrated our attention on manufacturing tolerances and quality of materials for the bearing, CNC bearing cover, and crown race. Now that this junction is steadfast you can rest assured that your cockpit’s steering stiffness will transfer onto the fork. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: In this particular model headset we’ve gone to a 1.5” bottom race to fill a tapered head tube. This mates with our oversized X5 carbon fork. Larger and smoother contact areas spread the load effectively and counteract flex. FEATURES - Oversized Technology™ - Massive 1.5” Diameter - Massive Sealed Bearings - Star-Nut Compression System - Includes 1-?” Reducer Race for 1-1/8” Steerer Tube COMPATIBILITY - Box One X5 Fork - Box One X2 Fork - Box One XL Fork - Frames with an Integrated NON-Tapered Head Tube

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. Available as a multi-shift (pull several gears at once) or single-shift shifter (a sound choice for e-bikes).
