Enduro Bearing 1-9/16" × 29/32" 543 2RS MAX Lefty
What Is It?
The Enduro Bearing 543 2RS MAX Lefty is a specialized sealed cartridge bicycle bearing designed primarily for Cannondale Lefty suspension forks and other specific high-precision MTB applications.
Unlike standard metric bearings, this one uses an imperial sizing format (1-9/16" × 29/32"), making it a purpose-built replacement part for specific fork and hub designs, especially Lefty systems where precision alignment and durability are critical.
The MAX design provides increased load capacity, while the 2RS sealing protects against contamination.
Key Features
