Description
2.5-piece cranks tested and approved by Bruno Hoffmann
The Spire BMX Cranks by Éclat are crafted as a 2.5-piece system. Although similar to a 3-piece system, the 2.5-piece system is simpler to install and is only adjustable from one side. The Spire features robust boxed arms that enhance both stiffness and resistance to dents.
Prior to reaching the retail market, the Spire underwent over a year of testing by the legendary pro rider Bruno Hoffmann, ensuring a final product that is both highly reliable and durable.
