TOOPRE Bike Crown Race Setting Tool, 45# Steel & Aluminum Alloy Fork Crown Race Installer for MTB Road Bike 28.6mm 1.25” 1.5” Forks

The TOOPRE Bicycle Crown Race Setting Tool is designed for installing the headset crown race / bottom race onto bicycle front forks. It helps drive the crown race evenly and accurately into position, making fork and headset assembly easier, safer, and more professional.

Made from 45# steel and aluminum alloy, this tool combines strength, durability, and smooth operation. The 45# steel sleeve is CNC-machined and heat-treated for high hardness, long service life, and excellent impact resistance. The aluminum alloy inserts are lightweight and precisely shaped to match different fork crown race sizes.

This crown race installer is compatible with standard 28.6mm outer diameter straight fork steerer tubes, 1.25-inch non-standard tapered forks, and 1.5-inch standard tapered forks. The set includes both a 30mm straight tube insert and a 1.5-inch tapered tube insert, allowing one tool to meet multiple installation needs.

The arc chamfer design fits the crown race angle, helping reduce the risk of scratching or damaging the headset bottom race during installation. With a smooth polished surface and comfortable handling, it is ideal for bike repair shops, professional mechanics, and home bicycle maintenance.
