The Box Three Crankset is a 2-piece powerhouse designed to maximize your frame stiffness during BMX racing. Utilizing a hollow-forged 6061-T6 aluminum construction, this set provides an oversized bottom bracket interface that rivals the rigidity of a pro fork. The 24mm Chromoly spindle is pressed directly into the drive-side arm for enhanced durability, ensuring every ounce of torque from your pedals is delivered to the rear hub.

Engineered for reliability, the non-drive side features a 2-bolt pinch system for even clamping force, while the 104 BCD spider includes a flex-resistant ring to keep your chain perfectly aligned. This setup ensures that whether you are pulling on the handlebars at the gate or carving turns on high-pressure tires, your bike maintains total composure. Steel inserts provide a bombproof connection for your pedals, supporting riders up to 115kg.

• System: 24mm Chromoly spindle with external BSA bottom bracket (included)
• Security: Dual pinch bolts and steel pedal inserts (requires washers)
• Geometry: 44.5mm chainline for optimal rim and spoke clearance
• Hardware: 104 BCD 4-bolt spider tuned for elite-level chainring performance
