Box Components Quick Release Seat Clamp

Box Two™ Quick Release Seat Clamps are cold-forged, and CNC machined from 6061-T6 aluminium alloy. Weighing in at just 28 grams/ 0.95 ounces in the 31.8 size, they are as lightweight as tough. The head of the quick-release lever and the face of the clamp are given a proprietary low-friction surface treatment that ensures smooth lever action for the life of the clamp without the need for a bushing. Meets or exceeds ENM standards

Box Components Hex Lab Carbon Rim - 20"

All Hex Lab rims are engineered to be front and rear specific and crafted using Oversized Technology. Box have carefully studied the load paths from the bars through the stem, headset, fork, axle, hub to the spokes and into the rim for steering stiffness. The same approach was taken via the pedals through the cranks and other components on the way to the rear rim for pedalling stiffness. That extra stiffness will net you more power to the ground out back, and upfront, you'll feel in control. When combined with Box's other Oversized components, you'll experience heightened responsiveness and reduced latency. Due to their compatibility with tubeless and tubed configurations, these rims have a broad range of tire options and setup possibilities, making them perfect for any track. The Hex Lab Carbon BMX Rims are the only rims in the Box line-up to be blessed with Oversized Technology. They are also the only model to use Ultra High Modulus Carbon Fibre (stiffer than other carbons variants). Take notice of the unique Symmetrical Dihedral Angle Stabilizers. Yes, it’s a mouthful but each of those words carries meaning. The sculpted bullet-shaped spoke beds are designed to bridge the angle between the rim's angled flanks and the vertical plane. With that, we achieve the stability, stiffness, and durability of a much broader rim profile without actually taking on most of the extra material.

Box Components Four 8-Speed E-bike Cassette

The Box Four E-Bike Cassette offers high gears with more teeth to withstand the rigours 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! Box Four adapts our Prime 9 philosophy of durability, simplicity, and reliability at a great price point. All sprockets are stamped from steel, given our durable black coating and then the larger sprockets are pinned to each other with spacers for easy installation.

Box Components Three Prime 9 E-Bike Cassette

The Box Three E-Bike Cassette offers high gears with more teeth to withstand the rigours 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 its Box One and Box Two siblings to create a sensible all-rounder. All sprockets 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 sprockets.

Box Components Two Prime 9 E-Bike Cassette

The Box Two E-Bike Cassette differentiates itself from its non-e-bike sibling by offering the 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! All sprockets 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 and perfect for any E-MTB.
