Fulcrum | Campagnolo Hub Axle Adapters Rear HH12 To QR

Fulcrum & Campagnolo KITFCRAQR

Rear Hub Conversion Kit – Thru-Axle (HH12) to Quick Release (QR 10x135 mm)

Product Description

The Fulcrum / Campagnolo KITFCRAQR is a genuine OEM conversion kit designed to transform compatible Fulcrum and Campagnolo rear hubs from a 12 mm thru-axle (HH12) configuration to a 10 mm quick release (QR) standard with 135 mm spacing.

Engineered for seamless integration with Fulcrum’s modular hub systems, this kit enables compatibility with traditional QR frames while maintaining correct hub alignment and bearing performance.

This conversion kit is intended to be used in conjunction with the RM16-TA12135 adapter, which defines the required 135 mm hub spacing.

Key Functions

1. Axle Type Conversion

Converts: 12x135 mm thru-axle (HH12) → 10x135 mm quick release (QR)

2. Modular System Integration

• Works as part of Fulcrum’s interchangeable axle system
• Interfaces directly with: RM16-TA12135 (135 mm adapter base)

⚠️ Important Compatibility Note

KITFCRAQR does NOT define hub spacing on its own.

• Requires: RM16-TA12135 for 135 mm configuration
• Not compatible with 142 mm setups unless spacing is first converted

Equivalent Campagnolo Wheelsets

Because Fulcrum is a subsidiary of Campagnolo and shares hub architecture and engineering platforms , the following Campagnolo wheel families use functionally equivalent hub systems and are typically compatible with the same axle/end-cap standards:

High-End Alloy / Performance Wheels

• Shamal / Shamal Mille
• Eurus
• Zonda

Mid-Range Alloy Wheels

• Scirocco
• Khamsin

Carbon Road Wheels (Hub Platform Shared Concepts)

• Bora One / Bora Ultra (selected generations)
• Bora WTO (hub architecture lineage, verify axle standard)

⚠️ Campagnolo Compatibility Notes

Fulcrum and Campagnolo share engineering DNA but are not always 1:1 interchangeable

Compatibility depends on:

• Hub generation
• Axle system (modular vs fixed)
• Bearing type (cup-and-cone vs cartridge)

Always verify the specific hub model before confirming compatibility on Campagnolo-branded wheels.

Compatibility Summary Table

Installation Overview

1. Ensure hub is configured to 135 mm (RM16-TA12135 installed)
2. Remove thru-axle end caps
3. Install KITFCRAQR components
4. Insert QR skewer (not included)
5. Verify alignment and secure fit

Engineering Notes

• Converts axle interface only, not hub geometry
• Maintains correct bearing preload and hub alignment
• Designed for Fulcrum hubs with modular end-cap architecture
• Enables compatibility with legacy QR frames

Summary

The Fulcrum KITFCRAQR is a critical conversion component that allows modern Fulcrum hubs to be used with quick release frames, when paired with the appropriate 135 mm adapter. It is essential for riders transitioning between axle standards or maintaining mixed bike setups.
