💡 What causes wandering handlebars and grinding noises on rough trails?

A displaced crown race forces the lower bearing to tilt and grind under pressure. Upgrading old rings keeps your ride handy and predictable:

- Hardened metal surfaces maintain perfect roundness after thousands of hits

- Straight bearing alignment delivers sharp turning response on steep descents

- Consistent seating depth prevents unwanted play inside the bottom bracket shell
