Product Description

A Next-Generation Titanium Derailleur Hanger for Giant TCR, Propel & Defy

Most replacement derailleur hangers are conventional CNC-machined aluminum components.

TiNE ECCLOS CryoFusion is engineered differently.

Developed specifically for selected Giant TCR, Propel, and Defy road bike platforms, this premium rear derailleur hanger combines advanced BESO bi-directional topology optimization with ECCLOS CryoFusion αβ-64 titanium alloy technology.

The result is an ultra-light, high-strength derailleur hanger engineered for:

• Precise rear derailleur alignment

• Exceptional structural efficiency

• Outstanding fatigue resistance

• Superior corrosion resistance

• Premium biomimetic aesthetics

• Long-term drivetrain reliability

This is not a generic replacement hanger. Its geometry is developed around the rear dropout architecture of compatible Giant road frames for precise fitment and clean integration.

Designed Specifically for Giant TCR / Propel / Defy

Compatibility

Compatible with selected:

• Giant TCR

• Giant Propel

• Giant Defy

Please confirm your exact frame model and model year before ordering.

Because Giant has used different derailleur hanger designs across model years and frame generations, compatibility should always be verified before installation.

If you are unsure, please send us:

• Exact bike model

• Model year

• Clear photo of the original derailleur hanger

• Clear photo of the rear dropout area

We can help confirm compatibility before shipment.

Why ECCLOS CryoFusion?

Unlike traditional aluminum derailleur hangers, ECCLOS uses digital structural optimization to determine exactly where material is required.

Instead of relying on conventional geometric machining, every structural curve and transition is developed around simulated load paths and stress concentration points.

The result is a hanger designed to be:

• Lighter

• Stronger

• More structurally efficient

• More fatigue resistant

• Highly corrosion resistant

• Precisely aligned for consistent shifting

• Better suited to premium performance road bikes

CryoFusion αβ-64 Titanium Alloy

ECCLOS CryoFusion αβ-64 is based on premium TC4 titanium alloy and uses a proprietary low-temperature αβ phase optimization process.

Compared with conventional aluminum derailleur hangers, the CryoFusion titanium structure provides an excellent combination of:

• Ultra-high tensile strength

• Excellent fatigue resistance

• Superior corrosion resistance

• High stiffness-to-weight efficiency

• Long-term durability

• Premium metallic appearance

Engineered for riders who want more than a standard replacement hanger.

BESO Bi-Directional Topology Optimization

ECCLOS uses BESO — Bi-directional Evolutionary Structural Optimization to refine the hanger according to simulated load conditions.

Rather than simply removing material to reduce weight, the structure evolves according to where strength is actually required.

Benefits

• Reduced unnecessary material

• Optimized stress distribution

• Improved stiffness-to-weight ratio

• Reinforced critical mounting areas

• Lightweight biomimetic structure

• Higher overall structural efficiency

Biomimetic Topology Design

The distinctive ECCLOS shape is not purely cosmetic.

Its organic geometry is generated through topology optimization, allowing material to follow real structural load paths rather than relying on conventional straight-line CNC geometry.

This creates a unique technical appearance while maintaining reinforcement around critical interfaces between:

• Frame dropout

• Derailleur hanger mounting area

• Rear derailleur

The result complements the clean, lightweight performance design language of the Giant TCR, Propel, and Defy platforms.

What Makes ECCLOS Different?

Ultra-Light Performance

Every gram matters on a premium race bike.

ECCLOS removes unnecessary material while preserving structural integrity, making it ideal for:

• Lightweight road builds

• Climbing-focused setups

• Aero race bikes

• Endurance road bikes

• Premium custom builds

• Performance-oriented riders

For Giant riders, this makes the hanger especially suitable for:

• TCR — lightweight race and climbing builds

• Propel — aero road race builds

• Defy — premium endurance road builds

Precision Rear Derailleur Alignment

A derailleur hanger directly affects shifting quality.

Precision manufacturing helps maintain:

• Correct rear derailleur positioning

• Accurate indexing

• Smooth gear changes

• Stable derailleur alignment

• Consistent drivetrain performance

Ideal for modern mechanical and electronic drivetrain systems.
