Box Four 8 Speed Drivetrain GroupsetReady for blasting across the MTB trails, this 8 speed groupset delivers smooth and reliable performance on every mountain bike ride. It is designed for riders who want less fuss and 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 operation, 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 ShifterThe 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 Fibre / 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: 128gBox Four 8 Speed Wide Rear Derailleur BlackThe 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: Aluminium, Glass Fibre / 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: 328gBox Four 8 Speed 11-42T CassetteThe 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: 473gBox Four 8 Speed 116 Link Chain NaturalThe 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: 364gBuy Box Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Box Two Prime 9 Speed MTB GroupsetReady for fast and fun MTB adventures, this groupset offers incredibly smooth gearing and precise operation on your mountain bike. It delivers similar performance to the top-tier Box One without the costly features. You still get the Tri-Pack (TM) Clutch in the rear mech only it isn't adjustable. The cassette's 11-50T range is equally impressive and the action on the shifter is just as snappy although you don't get the rigid die-cast pull lever. Completing this groupset is its high-quality chain, which boasts impressive torque power and speed as you explore the trails on your mountain bike.Box Two Prime 9 ShifterThe 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 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.Features: Material: Glass Fibre / Nylon Composite, Steel, Aluminum Alloy with Matte Onyx finish Hinged and Extruded Clamp 2 pc Pull Lever / Up to 3 Gears Per Shift* ( two options available to select) 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 non-adjustable Tri-Pack Clutch, bushing pulleys, and some muted finishes. Box Two rear derailleurs are still optimized for 11-50t cassettes and offer durability and performance for the most demanding terrain, just at a lower price!Features: Material: Stainless Steel, Hardened Alloy Steel with Matte Onyx finish Tri-Pack Limited Slip Clutch Sealed Bushings Pulleys Nylon Composite Knuckle Pivot-Tech Cable Stay Durable 3D Forged Linkages Forged Inner and Outer Cage Prime 9 Technology Compatible with Standard Derailleur Hangers (Non Direct-Mount) Weight: 290gBox Two Prime 9 11-50T CassetteThe Box Two cassette was where Prime 9 started. Originally conceived as an E-MTB product to deliver long service life and extra range over fewer gears, we quickly grew to enjoy its abilities on unpowered MTBs. All cogs are stamped from steel and subsequently, the larger ones are pinned to alloy spiders. Due to its provenance, this is, without doubt, the most durable cassette in the range.Features: Material: Hardened Alloy Steel, Aluminium Cogs Pinned to Lightweight Spiders Ultra-Wide Ratio with Consistent Progression Prime 9 Technology Our Most Durable Cassette Compatible with HG Freehub Bodies Not Intended for E-Bike Use Weight: 645gBox Two Prime 9 126 Link Chain NickelThe 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. 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.Features: Material: Hardened Alloy Steel with Nickel finish Our Most Durable Chain Nickel Plated Protection Durable Hardened Solid Pins Wide/Narrow Chainring Compatible Prime 9 Technology Weight: 350gFAQSHIFTERDoes the Box Two Prime 9 Shifter come with a cable?
