The Box Four shifter's main features aren't strikingly different from Box Three's. The key difference is its 8-speed platform. We've chosen to modernize the 8-speed in much the same way we did the 9-speed for Prime 9. Just like the Prime 9, the Box Four shifters take advantage of the "less is more" theme and exploit durability, simplicity, and reliability. Available as a multi-shift (pull several gears at once) or single-shift shifter (a sound choice for e-bikes). -Our 8 is Enough Shifter -Lightweight Extruded Clamp -Responsive 2 Piece Pull Lever -MTB Style Release Lever (V2) Weight: 128g/4.5oz

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 Three E-Bike Cassette offers high gears with more teeth to withstand the rigors of modern E-Bike riding. Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! The Box Three E-bike cassette draws from both of its Box One and Box Two siblings to create a sensible all-rounder. All cogs are stamped from steel and subsequently, the larger ones are pinned to steel spiders. The main difference here versus Box Two is the use of additional weight-reducing holes on the cogs.
