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

The Box Three shifter makes good use of nylon composites in both top and bottom shells as well as the levers. Box Three is our performance and value tier. So this shifter sheds all the fancy trappings of the top 2 tiers but maintains their shifting characteristics. 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).

The Box One Disc Brake Adapter is designed to improve braking control on frames where disc brakes were not standard. Compatible with 2 types of dropouts and 3-10mm hubs, the Box Disc Brake Adapter goes over your hub’s axle and mates with the frame’s dropout in the right configurations allowing mounting of a standard post mount disc brake caliper. Please note this product is NOT universally compatible. We strongly recommend reading the Compatibility and Installation instructions for details before purchasing. FEATURES - 3-10mm hub - 6061-T6 aluminum - 140mm Brake Rotor Only - Post Mount Caliper Compatibility - 150lb Rider Weight Limit

The Box Four cassette adapts our Prime 9 philosophy of durability, simplicity, and reliability at a great price point. All cogs are stamped from steel, given our durable black coating and then the larger cogs are pinned to each other with spacers for easy installation. - Compatible with HG freehub bodies - Steel stamped cogs - No spiders - Wide ratio and consistent progression - ED black protection

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.

The Box Four Rear Derailleur is the base of Prime 9 Technology that offers an affordable clutch based 1 by 8-speed derailleur that is simple and light; this makes it a perfect candidate for every entry-level bike that traditionally has a 3 by drive-train that is neither durable nor user friendly.

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.
