Product Description

The Future of Derailleur Hangers Starts Here.

Most derailleur hangers are simply machined from aluminum.

ECCLOS CryoFusion is engineered differently.

Developed using BESO bi-directional topology optimization and manufactured from an exclusive CryoFusion αβ-64 Titanium Alloy, this derailleur hanger delivers an entirely new balance of strength, weight, stiffness, aerodynamics, and drivetrain protection.

Designed specifically for modern Specialized UDH-equipped frames, it offers superior impact resistance while maintaining exceptional shifting precision for demanding riders.

Why ECCLOS CryoFusion?

Unlike conventional aluminum derailleur hangers, the ECCLOS CryoFusion Series is built around advanced engineering rather than traditional machining.

Every curve, every transition, and every gram has been optimized through digital structural simulation.

The result is a derailleur hanger that is:

• Stronger
• Lighter
• More aerodynamic
• Better protected against impact
• Optimized for modern fully integrated cable routing

Key Features

CryoFusion αβ-64 Titanium Alloy

Manufactured using ECCLOS' proprietary CryoFusion αβ-64 Titanium Alloy process based on aerospace-grade TC4 titanium.

Benefits include:

• Higher tensile strength
• Increased fatigue resistance
• Exceptional corrosion resistance
• Outstanding durability
• Long service life

BESO Topology Optimization

Instead of removing material randomly, ECCLOS uses BESO (Bi-directional Evolutionary Structural Optimization) to digitally evolve the structure according to real-world stress distribution.

Advantages:

• Material only where strength is required
• Reduced unnecessary weight
• Higher structural efficiency
• Better stiffness-to-weight ratio

Ultra-Light Design

Every gram matters.

The optimized topology design significantly reduces weight while maintaining exceptional structural integrity.

Ideal for:

• Road Racing
• Gravel
• Climbing Bikes
• Lightweight Builds

Superior Frame Protection

The derailleur hanger acts as the sacrificial component during impacts.

ECCLOS has optimized deformation characteristics to help protect both:

• Your frame
• Your rear derailleur

from expensive crash damage.

Hidden Cable Routing Friendly

Specifically engineered to work with modern internally routed drivetrains.

Benefits include:

• Cleaner appearance
• Reduced cable friction
• Improved shifting performance

Precision CNC Finishing

Every hanger is precision machined and finished to ensure:

• Accurate derailleur alignment
• Smooth shifting
• Perfect fit
• Professional appearance

What Makes ECCLOS Different?
