The SD Pro Bob is a high-performance BMX race component engineered for riders who prioritize a lightweight chassis without sacrificing frame stiffness. Designed to deliver excellent power transfer from the starting gate to the finish, these cranks ensure your pedal strokes are converted into pure forward momentum. The rigid construction rivals the structural integrity of a professional fork, providing a solid feel when pulling on the handlebars during an explosive sprint.

Equipped with a standard 24mm spindle and a 112mm axle length, the Bob 4-Hole offers a robust interface that integrates perfectly with the included Outboard (OB) Euro bottom bracket. The 104mm BCD spider is precision-machined to maintain chain alignment, ensuring smooth engagement with your rear hub and rim. Whether you are carving berms on 20-inch tires or stabilizing your stem through a rhythm section, this bike setup provides elite responsiveness.

• Interface: 104mm BCD 4-hole pattern with 4 black chainring bolts included
• Bottom Bracket: High-quality OB Euro BB for reduced friction and spoke-loading durability
