Product Details

Overview & Technology

DROPOUT-323 from Wheels Manufacturing is a precision replacement derailleur hanger designed as a direct-fit solution for select Specialized frames. Machined from 6061-T6 aluminium, each hanger is CNC-cut to tight tolerances to restore derailleur alignment and protect your frame in a crash or impact. The black anodized finish increases corrosion resistance and wear life while preserving a clean factory look. Wheels Manufacturing includes M3x6 socket-head screws and supplies both left and right hanger halves as a pair, so you get everything needed for a straight swap and reliable shifting performance.

Key Features

Material & construction: Made from 6061-T6 aluminium using CNC machining for consistent thickness, true mounting faces, and predictable deformation characteristics in an impact. The anodized surface helps resist salt, grit, and moisture. • Pair includes both hanger halves for left and right sides where applicable. • Black anodized finish for durability and low visibility on the frame. • Includes M3x6 socket-head screws—ready to install out of the box.

Fit & Compatibility

This DROPOUT-323 is listed for "Specialized" under the manufacturer's misc field — it matches the specific hanger pattern used on a range of Specialized models. Wheels Manufacturing produces precise copies of OEM hanger profiles; however fit varies by model year and frame variant. Before ordering, confirm your frame's hanger pattern by checking your bike's existing hanger for the part number or compare photos and dimensions on Wheels Manufacturing's compatibility chart. Shipping dimensions and weight are compact (2.15" x 1.101" x 1", 0.1 lb), so this part is lightweight and easy to carry as a spare on rides.

Who It's For

This hanger pair is aimed at road cyclists and mechanics who need an OEM-style replacement for Specialized frames. If you've bent or broken a hanger, DROPOUT-323 restores derailleur geometry for crisp shifting and reduces the risk of frame damage by replacing a sacrificial component. It's also a smart spare to carry on long rides or to keep in a home workshop — lightweight, affordable, and simple to swap with common hex tools.

Frequently Asked Questions

Is DROPOUT-323 sold as a single hanger or a pair?

The DROPOUT-323 is supplied as a pair and includes both sides of the derailleur hanger. Wheels Manufacturing ships the left and right hanger halves together along with the M3x6 socket-head screws for a complete replacement.

Will this hanger fit my Specialized bike model?

This hanger matches the DROPOUT-323 pattern used on select Specialized frames. Fit depends on the specific model and model year — confirm by comparing your existing hanger's shape or part number, or consult Wheels Manufacturing's compatibility listings to ensure an exact match.

What tools and torque should I use when installing?

Install using the supplied M3x6 socket-head screws and a correctly sized hex key. Tighten to the frame manufacturer's recommended torque where available; if uncertain, use a modest setting (roughly 2 Nm) and avoid over-tightening to prevent thread damage. Threadlocker is not usually required but may be used per frame maker guidance.

Why choose 6061 aluminium for a derailleur hanger?

6061-T6 aluminium balances strength, light weight, and predictable failure behavior. A machined aluminium hanger provides consistent alignment and will bend or break before damaging the frame's dropout, acting as a sacrificial part in crashes or impacts.

Are replacement screws included if I lose them?

Yes — the DROPOUT-323 package includes M3x6 socket-head screws required for mounting. If you lose them, standard M3x6 stainless or alloy socket-head screws are suitable replacements, but match thread type and length carefully to avoid damaging the frame.

Can I use this hanger for a frame repair after a crash?

Yes — replacing a bent or broken hanger with a precise CNC part like the DROPOUT-323 restores derailleur geometry and shifting performance. Inspect the frame dropout for damage before installation; if the frame itself is distorted, a hanger swap alone may not fully correct shifting issues.

Buying Guide

When buying a derailleur hanger, match the hanger profile to your frame exactly — patterns vary widely between models and years. Look for part numbers on your old hanger, compare photos and mounting hole spacing, and consult the manufacturer's compatibility chart to avoid returns. Prioritize material and construction: CNC-machined 6061-T6 aluminium offers a good balance of weight, stiffness, and predictable sacrificial behavior. Also consider keeping a spare hanger and the correct screws in your repair kit to get back on the road quickly after a bent or broken hanger incident.
