Product Details

Overview & Technology

DROPOUT-373 from Wheels Manufacturing is a precision replacement derailleur hanger machined from 6061-T6 aluminum and finished with a durable black anodize. The CNC machining ensures tight tolerances for accurate derailleur alignment, minimizing indexing issues and premature drivetrain wear after installation. The part is a direct match to Specialized Part # S162600004 and ships light at just 0.05 lb. It bolts to the frame using a single M5x10 socket head screw (fastener not included), making it a simple, serviceable solution if your hanger gets bent or damaged on the road.

Key Features

Durable, serviceable construction: Made from 6061-T6 aluminum for an excellent strength-to-weight ratio and anodized for corrosion resistance. • Precision CNC machining for accurate derailleur alignment and repeatable fit. • Black anodized finish for aesthetics and protection against corrosion. • Direct replacement for Specialized S162600004 — no modification needed when matched to compatible frames. • Mounts with one M5x10 socket head screw; fastener not included.

Fit & Compatibility

This hanger is designed as a direct replacement for Specialized frames that use part number S162600004. If your frame's replacement number or hanger shape matches the DROPOUT-373, it will provide the same mounting points and derailleur geometry as the factory part. Before purchasing, confirm fit by comparing the old hanger's profile and mounting hole spacing to DROPOUT-373 or by checking your frame serial/parts diagram. Note that the required M5x10 socket head screw is not included; use a properly sized, grade-appropriate fastener and torque to the frame manufacturer's specification.

Who It's For

Road cyclists, mechanics, and home wrenchers who want a reliable, OEM-equivalent replacement for a damaged derailleur hanger will appreciate DROPOUT-373. It's ideal for riders who prefer a lightweight, corrosion-resistant aluminum part that restores correct derailleur alignment without custom fitting. Shops and touring riders who keep spare hangers on hand will value its compact size and interchangeability with Specialized's S162600004, making roadside repairs quick and dependable.

Frequently Asked Questions

Is the mounting screw included with the hanger?

No. DROPOUT-373 ships without the M5x10 socket head screw. Use a grade-appropriate M5x10 fastener (stainless or alloy) and follow your frame manufacturer's recommended torque specs.

How do I know this is the correct hanger for my bike?

Compare the part number on your replacement diagram to Specialized S162600004 or compare the hanger shape and mounting hole spacing to your original. DROPOUT-373 is a direct match to S162600004; if those match, it will fit.

Can this hanger be bent back if it's slightly misaligned?

Minor realignments are sometimes possible, but aluminum hangers can fatigue. For best shifting performance and safety, replace the hanger if it is visibly bent or if shifting problems persist after straightening.

What tools and torque should I use when installing it?

Install with an M5x10 socket head cap screw and use a torque wrench to avoid over- or under-tightening. Typical M5 thread torque ranges 3-6 Nm, but you should follow your frame manufacturer's specific recommendations.

Is this the same as the OEM Specialized hanger?

Yes. Wheels Manufacturing lists DROPOUT-373 as the same design as Specialized Part # S162600004 and manufactured to match OEM geometry and fit.

What are the benefits of 6061 aluminum and anodizing?

6061-T6 aluminum offers a great balance of strength and light weight; CNC machining delivers accurate geometry. Anodizing adds a protective oxide layer that improves corrosion resistance and wear characteristics while giving a clean, consistent finish.

Buying Guide

When replacing a derailleur hanger, match the hanger shape and part number to your frame first. OEM-equivalent hangers like DROPOUT-373 ensure the same alignment and mounting geometry as the original, which preserves shifting performance and reduces the need for further setup. Consider material and finish: 6061-T6 aluminum offers a strong, lightweight option while an anodized surface improves corrosion resistance. Keep a spare hanger and the correct M5x10 screw in your tool kit for quick roadside repairs.
