Subrosa Big Bitchin Cranks

Introducing the larger and tougher evolution of the original Bitchin cranks named the “Big Bitchin” cranks.

The Big Bitchin cranks utilize a hollow, 22mm, 48 splined spindle, and 100% Death Proof post-weld heat treatment on the arms for increased stiffness and strength.

The custom forged Subrosa shape tubing flawlessly wraps the spindle boss and the square design offers stability on crank arm slides, which was a feature the Subrosa team insisted on keeping. They also rounded the front of the spindle boss to reduce ankle damage and increased the crank arm angle for a wider stance while riding, and to easily clear any BMX frame.
