Product Details

Overview & Technology

Wheels Manufacturing Dropout 94 is a direct-replacement derailleur hanger made to restore frame alignment and protect your derailleur after impact. Designed for GT frames, this lightweight hanger (part #270403 / DROPOUT-94) is CNC-machined for repeatable tolerances and consistent shifting performance. Manufactured from heat-treated 6061-T6 aluminium with an anodized finish, the Dropout 94 balances strength and fracture-controlled breakaway behavior: it absorbs torsional force in a crash, bending or breaking at the hanger rather than ripping threads out of the frame. Shipping size is compact (3" x 3" x 0.4") and it weighs approximately 0.04 lb — a tiny part with an outsized role in drivetrain protection.

Key Features & Benefits

Precision CNC machining: tight tolerances keep your derailleur alignment true for crisp, reliable shifts and reduced drivetrain wear. The accuracy of the Dropout 94 helps maintain derailleur hanger alignment even under load. Durable materials and finish: 6061-T6 construction with an anodized surface resists corrosion and abrasion from the trail. The hanger is designed to perform as a sacrificial component — protecting expensive derailleurs and frame dropout threads in a crash, while being inexpensive and easy to replace. • Exact GT frame fitment — replaces factory #94 hanger • Lightweight yet strong construction for real-world riding • Consistent shifting and easy swap without frame modification

Fit, Compatibility & Installation

The Dropout 94 is specifically made to fit GT frames that use the #94 derailleur hanger spec. This hanger is a bolt-on replacement and installs with a standard hanger mounting bolt; depending on your frame, you may reuse the original hardware or fit the included/aftermarket M5-style bolt and washer. Always check thread engagement carefully before final tightening. Installation is straightforward: remove the damaged hanger, clean the mounting area, align the new hanger to the dropout, and torque the mounting bolt to the frame manufacturer's specification. If your derailleur required hanger alignment before replacement, it's wise to check the hanger alignment with a simple alignment gauge or at a local shop after installation to ensure perfect shifting.

Who It's For

This hanger is ideal for mountain riders who own GT frames and need an exact OEM-style replacement. Whether you ride trail, all-mountain, or weekend singletrack, keeping a correct-fit hanger like the Dropout 94 on hand saves time and money when crashes or falls bend or break the original. Bike mechanics, home wrenchers, and shop techs will appreciate the precise fit and proven materials — a small, affordable part that preserves drivetrain integrity and gets you back on the trail with minimal fuss.

Frequently Asked Questions

How do I know if Dropout 94 fits my bike?

Dropout 94 is made to replace the GT-specific #94 hanger. Check your frame documentation or compare the damaged hanger to photos/spec numbers. If in doubt, send a photo of your hanger area to our fit help or bring the bike to a shop to confirm compatibility.

What material is the hanger made from?

This hanger is CNC-machined from heat-treated 6061‑T6 aluminium with an anodized finish. That combination offers dependable strength, precise tolerances, and good corrosion resistance for long service life.

Can I reuse my original bolt when installing this hanger?

Often you can reuse the original mounting bolt if it is undamaged and threads properly. However, if the bolt is bent, corroded, or stripped, replace it. Use the frame manufacturer's recommended bolt type and torque value to ensure safe mounting.

Do I need a derailleur hanger alignment tool after replacement?

It's a good idea to check hanger alignment after installation. Even a perfect new hanger can require minor adjustment to match frame tolerance. A simple alignment gauge at home or a quick inspection at a bike shop will ensure optimal shifting.

What should I do if the hanger strips the threads in my frame?

If threads are damaged, avoid forcing a replacement bolt. Depending on the frame material, a helicoil/insert or professional thread repair may be necessary. Contact a qualified frame builder or bike shop for safe repair options.

Is this hanger intended for road or mountain use?

Dropout 94 is intended for GT mountain frames and designed to withstand the demands of off-road riding while providing sacrificial protection for your derailleur.

Buying Guide

When buying a derailleur hanger, the most important factors are exact fit and material construction. Look for OEM-replacement dimensions and mounting patterns (hanger number or part reference) to ensure bolt hole spacing and mounting geometry match your frame. CNC-machined 6061‑T6 aluminium hangers offer the best combination of lightweight performance and controlled breakaway characteristics. Also verify whether mounting hardware is included and whether you'll need a thread repair or hardware replacement. For mountain riding, prioritize hangers made to absorb impacts and protect stronger, more expensive parts like derailleurs and frame dropouts.
