The Box Two Square Taper Cromo Bottom Brackets are the best option for young BMX racers and other users of three-piece cranks in search of an affordable, high-performance square taper bottom bracket. Each bottom bracket is hand assembled with a chromoly spindle, sealed bearings, forged and CNC-machined alloy cups and a composite centre spacer/seal.
Extruded and CNC-machined from 6061-T6 aluminum, Box Two™ Stem Spacer Kits feature an ultra-minimalist design that is super lightweight. Weights range from 0.02 to 0.14 ounces (0.56 to 4 grams), depending on the size. For the best performance, stack the spacers so the vertical supports are in alignment. Sold in packs of five, each set provides spacing adjustments from 1 to 20 millimeters.
Designed by the late Rich Lee, Box Two plates feature colour-fast, 3D injection molding, making them some of the most intricate and stylish plates available today. Each plate includes hook-and-loop closures secured with custom Box rivets and silk-screened graphics. Airflow ports improve aerodynamics, reduce weight and add style. Box Two plates are the official number plate of the UCI/GSX Super Cross Series.
Box Two Hubs feature cold forged and CNC-machined, 6061-T6 aluminum shells fitted with precision sealed bearings and 20mm, 7075-aluminum axles and axle nuts. Besides 100mm long front and 110mm long rear spacing, they also feature oversize, 32mm dropout interface washers, which further increases the stiffness of the wheels. ###section### Product Specs HUB TYPE:Cassette AXLE:20mm DRIVER:Sold Separately SPOKE HOLES:36h WEIGHT:479g/16.9oz
Classed as Box's most durable shifter, this 9 speed model features a hard-wearing two-piece resin and steel lever construction, which makes it more than capable of handling all the intensity from exploring the MTB trails. 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 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.

The Box Two groupset 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.
