Specifications

• Model: A-HG045

  • The A-HG045 is a derailleur hanger, designed to securely attach the rear derailleur to the bicycle frame. It ensures proper alignment and durability, allowing the derailleur to shift gears accurately and smoothly.

• Use: Derailleur Hanger

  • The A-HG045 is specifically designed to serve as a derailleur hanger, which plays an essential role in shifting performance by maintaining the position of the rear derailleur. It helps ensure that the derailleur remains in the correct alignment with the cassette, which is critical for proper gear shifting.

• Fastener Type: 3-Fastener Design

  • The A-HG045 utilizes a 3-fastener design, which means the hanger is secured to the frame using three bolts or screws. This design provides a strong and stable attachment to the frame, which is ideal for ensuring the derailleur remains precisely aligned, even under heavy loads or impact.

• Material: Alloy

  • The A-HG045 is constructed from high-quality alloy, which ensures a strong, lightweight, and corrosion-resistant hanger. The alloy material makes the hanger durable enough to withstand the stresses of regular cycling while keeping the overall weight of the bike low.

• Color: Silver

  • The A-HG045 comes in a sleek silver finish, which is not only aesthetically appealing but also provides corrosion resistance. The silver finish is designed to withstand exposure to various weather conditions, helping to preserve the hanger's performance over time.

• Brand: AltaLine

  • AltaLine is a reputable brand known for producing high-quality bicycle components. The A-HG045 is made to AltaLine's high standards, offering cyclists a reliable and durable solution for their derailleur hanger needs.

Key Features

1. Durable Alloy Construction:

   • The A-HG045 is made from premium alloy, which is known for its strength-to-weight ratio and resistance to corrosion. This makes the hanger highly durable, capable of enduring the forces experienced during riding without warping or breaking. The alloy construction also ensures that the hanger remains lightweight, which is beneficial for overall bike performance.

2. 3-Fastener Design for Secure Attachment:

   • The 3-fastener design offers a more secure attachment compared to single or double fastener designs. The additional fasteners improve the overall stability and strength of the hanger, making it ideal for bikes that undergo frequent shifting or are exposed to rough terrain. The use of three bolts ensures that the derailleur remains properly aligned with the cassette, even under heavy loads or impacts.

3. Silver Finish for Aesthetic Appeal and Protection:

   • The silver finish on the A-HG045 not only enhances the appearance of your bike but also provides added protection against rust and corrosion. The silver finish is durable, able to withstand harsh outdoor conditions, ensuring that the hanger maintains its functionality and appearance for a longer period.

4. Enhanced Shifting Performance:

   • The A-HG045 is designed to keep the derailleur in the correct position for optimal shifting. Proper alignment ensures smooth and accurate gear changes, reducing issues like chain skips, mis-shifts, or derailleur damage. This hanger is an essential component for riders who prioritize shifting precision.

5. Shock Absorption:

   • The A-HG045 helps absorb shocks during impacts, such as those encountered during off-road riding or accidents. The hanger's material and design are built to absorb impacts, protecting the derailleur and bike frame from damage that could result from falls or sudden jolts.

Applications and Compatibility

1. Road Bikes:

   • The A-HG045 is compatible with road bikes, providing strong support for the rear derailleur and ensuring smooth, accurate shifting performance. The 3-fastener design and alloy material make it a durable and reliable choice for road cyclists who prioritize performance.

2. Mountain Bikes:

   • The A-HG045 is ideal for mountain bikes, where the derailleur hanger is subjected to more stress due to rough terrain, jumps, and technical riding. The additional fasteners ensure that the derailleur stays securely in place even during high-impact riding, and the alloy material is strong enough to withstand the demands of off-road biking.

3. Gravel Bikes:

   • For gravel bikes that often encounter mixed surfaces, the A-HG045 provides the necessary durability and support for reliable shifting performance. The 3-fastener design ensures that the hanger stays securely attached, even when navigating bumpy or uneven gravel paths.

4. Commuter Bikes:

   • The A-HG045 is also suitable for commuter bikes, where reliable shifting is essential for daily rides. The alloy construction provides the durability needed for regular commuting, and the silver finish adds a touch of style while protecting the hanger from rust or corrosion in urban environments.

5. Touring Bikes:

   • Touring cyclists who require durable components for long-distance travel will benefit from the A-HG045. The 3-fastener design ensures that the derailleur stays properly aligned even during long rides, while the alloy material can handle the wear and tear associated with extended use.

Maintenance and Care

1. Check Alignment Regularly:

   • It is important to check the alignment of the A-HG045 periodically to ensure that the rear derailleur remains properly aligned with the cassette. If the hanger is bent or misaligned, it can cause shifting problems and damage the derailleur. Use a derailleur alignment tool to make any necessary adjustments.

2. Tighten Fasteners Properly:

   • Ensure the fasteners are securely tightened to the recommended torque specifications. While the 3-fastener design provides a stable attachment, over-tightening or under-tightening the bolts can lead to poor performance or damage. Use a torque wrench to apply the correct amount of force.

3. Clean the Hanger Regularly:

   • Regular cleaning is essential to maintain the A-HG045. Use a soft brush and mild detergent to remove dirt, grime, and moisture that may accumulate on the hanger during rides. Keeping the hanger clean will help prevent rust and extend its lifespan.

4. Inspect for Damage:

   • Regularly inspect the A-HG045 for signs of wear, such as cracks, bends, or other forms of damage. If the hanger is damaged, it should be replaced immediately to avoid affecting the shifting performance or causing further damage to the derailleur or frame.
