The all-new SD B-85 Crankset is a BMX race masterpiece, engineered for athletes seeking an unfair advantage at the starting gate. Combining extreme rigidity with a lightweight hollow-arm profile, it maximizes the power transfer through your frame for instant acceleration. The B-85 features a unique direct-mount hardware system where hex bolts screw directly into the crank arm, eliminating the need for two-piece chainring bolts and ensuring a clean, sleek aesthetic.

With a 24mm spindle and a 112mm axle length, this setup provides a rock-solid interface with your bottom bracket, rivaling the stiffness of an elite fork and handlebar combo. The 104mm BCD spider is optimized for rapid gearing changes, allowing you to fine-tune your bike for different tracks. Whether you are sprinting on 20-inch rims or pulling on your grips for a holeshot, the B-85 ensures every pedal stroke is perfectly efficient.

• System: 24mm alloy axle for maximum torque and frame stability
• Interface: 104mm BCD diameter with "Hidden Bolt" direct-thread technology
• Finish: Stealthy matte black with glossy decals to match your stem and seat
• Durability: Built to withstand high-wattage chain tension and heavy landings
