Product Details

Overview & Technology

Wheels Manufacturing Dropout 65 is a precision replacement derailleur hanger made to mirror the OEM Specialized #65 dropout. Engineered as a direct-fit spare, this hanger restores correct geometry and shifting performance after impact, crash, or wear. The hanger is CNC-machined from high-strength aluminum and finished for corrosion resistance, giving you a lightweight part that maintains alignment and resists fatigue. Using a dedicated replacement hanger keeps your frame threads and derailleur mounting interface protected, making repairs quick and reliable.

Key Features & Benefits

Precision fit: The Dropout 65 reproduces the factory mounting pattern and hanger profile so the derailleur mounts exactly where the manufacturer intended. That keeps your drivetrain indexing accurate and reduces risk of dropouts or chain rub. Durable construction: CNC-machined aluminum provides an excellent strength-to-weight ratio and consistent tolerances. A corrosion-resistant finish helps the hanger stand up to wet rides and seasonal storage, while the lightweight design keeps unsprung mass low.

Fit, Compatibility & Installation

The Dropout 65 is designed specifically for Specialized frames that use the #65 hanger. Verify compatibility by comparing the shape, bolt pattern, and part number to your existing hanger or using Wheels Manufacturing's fit guide. If you're unsure, remove the old hanger and compare profiles or consult Forest Bikes customer support with your frame model and year. Installation is straightforward: align the hanger with the frame mounting bosses, install the mounting hardware, then torque to the frame manufacturer's specification. If hardware isn't provided, reuse the OEM bolt or choose the correct stainless fastener. After installation, check derailleur alignment and fine-tune indexing; use a derailleur hanger alignment gauge if the bike experienced a crash.

Who This Hanger Is For

This hanger is for riders who own a Specialized bike that uses the #65 dropout and need a reliable replacement after bending or breakage. It's ideal for trail and mountain riders who want a lightweight, precise spare that restores factory geometry quickly. Mechanics, home wrenches and bike shops will appreciate the straightforward direct-fit design that eliminates guesswork during repairs. Keep a spare Dropout 65 in your toolkit or kit bag to minimize downtime after impacts on the trail.

Frequently Asked Questions

How do I know if Dropout 65 fits my Specialized frame?

Compare your existing hanger to the #65 profile or consult Wheels Manufacturing's fit guide. You can also remove the old hanger and visually match bolt pattern and shape — if they match, Dropout 65 is the correct replacement.

Is mounting hardware included with the hanger?

In many cases the hanger ships as the drop-out only; mounting hardware may or may not be included depending on the vendor. If hardware isn't provided, reuse the OEM bolt or fit a suitable stainless-steel fastener sized to your frame's threads.

Can I ride with a bent hanger, or should I replace it immediately?

A bent hanger can cause poor shifting, chain drop, or derailleur damage. Don't ride on a visibly bent or cracked hanger — replace it promptly or straighten and check alignment with a gauge before riding again.

How should I torque the hanger mounting bolt?

Always follow your frame manufacturer's torque specification when available. If unknown, a conservative range for small hanger bolts is typically 4–8 Nm. Use a calibrated torque wrench and avoid over-tightening to protect frame threads.

Do I need a derailleur hanger alignment tool after installing this part?

Yes — after installation it's recommended to check alignment with a derailleur hanger alignment gauge. Even new hangers can sit slightly out of plane after install; straightening ensures crisp, reliable shifting.

What material is the Dropout 65 made from?

The Dropout 65 is CNC-machined from high-strength aluminum alloy and finished for corrosion resistance to provide a lightweight, durable replacement for your Specialized frame.

Buying Guide

When buying a replacement derailleur hanger, always match the OEM number or visually confirm the mounting pattern and profile. Wheels Manufacturing maintains a cross-reference of hanger numbers — use that resource or our product photos to ensure proper fit. Consider whether mounting hardware is included; if not, plan to reuse the OEM bolt or purchase the correct stainless replacement. Keep an alignment gauge and torque wrench at hand when fitting a new hanger. Correct alignment and proper torque are essential for reliable shifting and to protect both your derailleur and frame. For trail riders and commuters alike, keeping a spare hanger in your toolkit is a cheap insurance policy against a ride-ending impact.
