29mm Crank Spindle CNC Machined Splined Crank Spindle Black Bike Part

This cycle component is a black DUB29 crank spindle designed for EVOSID cranksets, with identification text printed directly on the part. Its 29 mm size and splined ends define the core interface, making the piece easy to recognize when matching drivetrain parts. CNC machining shapes the spindle shaft into a smooth cylindrical body with consistent edges and a neat matte surface. That careful construction supports an exact fit and helps the part look orderly once installed inside the crankset assembly. As a splined crank spindle, it is built around the connection points that are most important in the crank interface. The visible splines and labeled DUB29 marking make it straightforward to identify during setup, replacement, or part matching when working on an EVOSID crankset.
