The Federal Vice crank features a unique radius box section combined with a 24mm hollow 48 splined spindle to make these some of the strongest and stiffest bmx cranks on the market. The spindle and arms are both made from heat treated 4130 Chromoly and the spindle has been internally machined to reduce weight. The cranks are designed to take all the abuse of the modern street rider and the angular shape of the arms helps to make crank slides more stable. The braised logo gives the cranks a unique and distinct appearance. ###section### Product Specs Crank Type: 3pc Spindle Diameter: 24mm Includes BB: Yes Weight: 934g / 32.9oz ###shogun-image-section###
