Conversion kit for upgrading a classic Leleu 100 mm hub from loose ball bearings with cup-and-cone system to sealed cartridge bearings.

This solution provides improved operational reliability, reduced maintenance requirements, and more stable bearing play.

By converting to fixed cartridge bearings, the need for cone adjustment is eliminated, and the system becomes more tolerant to load variations.

Performance:

• Designed for 100 mm hubs
• Engineered for press-fit installation in the existing hub shell
• Intended for use with standardized sealed cartridge bearings
• Improved radial and axial stability
• Sealed bearing solution to reduce dirt ingress
