The Sunday Spline 19mm Crank Spindle is specifically designed for Sunday Saker v1 and v2 3-piece cranksets, but is also compatible with most OEM-style cranks that use a 19mm diameter and 8-spline (48-spline) interface. With a total length of 149 mm, it fits standard Mid BB bottom bracket shells, ensuring proper chainline and crank arm spacing.
Crafted from heat-treated, precision CNC-machined chromoly steel, the spindle offers excellent torsional stiffness, making it highly resistant to flex under heavy loads and long-term use. The finely machined splines provide a tight and secure fit with crank arms, minimizing play and maximizing power transfer.
This spindle is an ideal choice if you're rebuilding an existing setup or sourcing a reliable component for a fresh drivetrain build. The universal 19mm spec ensures compatibility with a wide range of 3-piece cranksets, making it a versatile replacement or upgrade.
Please note: Spindle bolts are not included and must be purchased separately.
