All cogs are stamped from steel and subsequently, the larger ones are pinned to alloy spiders. Due to its provenance, this is, without a doubt, the most durable cassette in the range and perfect for any E-MTB.

Our Box Four tier is for those people who just want less fuss! You're fond of Prime 9, but know 8 is enough, and surely 11-42T is plenty of range for an 8-speed cassette. Our derailleur still has the Limited Slip clutch but now arrives with a more compact cage. The custom 8-speed chain is built for abuse, although it's sophisticated enough to have its own Wide/narrow chainring. Push through fewer gears with a no-nonsense shifter. This combo will transport you to 1 by territory for less than $200.

Our Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform. Cassettes are accessible at 11-46T or 11-50T and fashioned with steel spiders. The derailleur exploits our Limited Slip clutch technology without the Tri-pack features. Shift easily with a comparable mechanism, although you'll forgo the hinged clamp and die-cast structure. And lastly, string it all together with a Prime 9 chain but without extravagant coatings. If you're looking to bring your 2/3 by bike into the 21st century, then level up with this group!

All Box One forks are engineered and crafted using our Oversized Technology. These forks are the most important component in the quest for bike control. We’ve moved carbon from areas of low stress to areas that handle high loads. Those muscular shoulders aren’t just for looks as they are integral to achieving superior steering stiffness. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: This particular model fork is tailored for larger-sized racers. It also takes our application of Oversized Technology one step further as it includes a tougher 1-1/8 inch chromoly steerer tube and stiffer 20mm through-axle cold-forged dropouts. Weight Limit: 115kg (253 lbs) with limitations per Category 2 of EN 16054:2012 Standard. FEATURES - Oversized Technology™ - Chromoly Steel Steerer Tube to Accommodate Larger-Sized Racers - 20mm Through Axle to Increase Responsiveness - Internal Butterfly for Added Durability at Steerer Tube and Fork Crown Interface
