The Box Four groupset is designed for riders who want less fuss. It features an 8 speed shifter and an 11-42T cassette, which offers a great range of gearing to meet the demands of your off-road adventures. Designed for smooth performance, its rear mech uses a Limited Slip clutch in a compact cage. A final highlight is its custom 8 speed chain that's built for abuse. This makes it a great groupset for riders that want strong groupset without all the frills and at a wallet-friendly price. Box Four 8 Speed Shifter 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. Features: Material: Glass Fiber / Nylon Composite, Steel Extruded Clamp 2 Piece Pull Lever / Up to 3 Gears Per Shift Resin Top Shell Fast Action Release Lever Not Intended for E-Bike Use Weight: 128g Box Four 8 Speed Wide Rear Derailleur Black 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. Features: Material: Aluminum, Glass Fiber / Nylon Composite, Steel Limited Slip Clutch Bearing Pulleys Nylon Composite Knuckle Direct Channel Cable Stay Die-Cast Linkages Stamped Inner and Outer Cage Compatible with Standard Derailleur Hangers (Non Direct-Mount) Weight: 328g Box Four 8 Speed 11-42T Cassette 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. Features: Material Cold Rolled Steel Steel Stamped Cogs No Spiders Wide Ratio & Consistent Progression ED Black Protection Compatible with HG Freehub Bodies Not Intended for E-Bike Use Weight: 473g Box Four 8 Speed 116 Link Chain Natural The Box Four chain employs an 8-speed platform in a similar strategy to the Prime 9 but at a great price point. The chain is polished and then chemically treated to achieve corrosion resistance. We engineered the inner link spacing to be a little tighter than other 8-speed chains and is optimized for use with our Box Four Wide/Narrow Chainring. Features: Material: Hardened Alloy Steel Durable Hardened Solid Pins Wide/Narrow 8 speed Specific Weight: 364
