Product Details

Overview & Technology

Wheels Manufacturing Dropout 133 is a direct-replacement derailleur hanger designed for Look and Raleigh road frames (Wheels Mfg #133 pattern). CNC-machined from high-grade aluminum for consistent tolerances, the Dropout 133 restores correct derailleur geometry after a crash or when an original hanger is bent or lost. The hanger's precise machining and tight tolerances ensure repeatable indexing and reduced risk of chain drops. At just 0.05 lb and with compact shipping dimensions, it’s an ideal lightweight spare to carry on long rides or keep in the workshop.

Key Features

Material & construction: CNC-machined alloy body delivers an excellent strength-to-weight ratio, corrosion resistance, and predictable deformation under impact to protect the derailleur. Designed for serviceability: The Dropout 133 mirrors the OEM mounting pattern used by Look and Raleigh frames so you can swap it in quickly with common hand tools and get back on the road with minimal fuss.

Fit & Compatibility

This hanger is Wheels Manufacturing part #133 and listed for Look and Raleigh road frames. If your frame used the OEM #133 pattern, this Dropout 133 will match the mounting holes and derailleur interface. Always verify the hanger number stamped on your old part or check OEM documentation before ordering. Installation typically uses the original mounting bolt or threaded insert on the frame — you may need the same bolt length and hardware as the original. If you’re unsure, bring the old hanger to a shop or compare measurements: look for identical hole spacing and the same bolt interface.

Who This Is For

Road riders, mechanics, and bike shops who need a reliable, lightweight replacement hanger for Look- or Raleigh-pattern frames will appreciate the Dropout 133. It’s perfect as a workshop spare, emergency in-frame replacement, or as part of a travel kit for racers and club riders who want fast recovery from a bent hanger. If you value precise shifting, fast repairs, and compatibility with common road frames, the Dropout 133 is an essential small part that protects expensive derailleurs and keeps your drivetrain working smoothly.

Frequently Asked Questions

How do I know if Dropout 133 fits my frame?

Check your original hanger for a stamped number or compare mounting hole spacing to Wheels Manufacturing #133 diagrams. Dropout 133 is intended for Look and Raleigh road frames that use the #133 pattern. If unsure, bring the old hanger to a mechanic or compare photos/specs before ordering.

What material is the Dropout 133 made from?

The hanger is CNC-machined from a high-grade aluminum alloy chosen for an excellent strength-to-weight ratio and predictable deformation in impacts to protect the rear derailleur.

Can I install this hanger at home?

Yes — installation is straightforward with basic tools. You’ll typically reuse the original mounting bolt or frame insert. Make sure threads are clean and torque the bolt to the frame manufacturer's specification, then check derailleur alignment before riding.

Will replacing the hanger fix my shifting problems?

Replacing a bent or damaged hanger often restores correct derailleur geometry and significantly improves shifting. After installation, fine-tune the rear derailleur indexing and check hanger alignment with a derailleur hanger alignment tool if shifting issues persist.

Is this an OEM part?

This is a Wheels Manufacturing aftermarket replacement manufactured to match the #133 pattern used by Look and Raleigh. Wheels Mfg hangers are high-quality CNC replacements designed to meet or exceed OEM fit and tolerances.

Do I need any extra parts to fit this hanger?

Most installs only require the original mounting bolt. If the original bolt is damaged or lost, match the thread pitch and length from the OEM specification or consult a mechanic. A hanger alignment gauge is recommended to verify perfect alignment after fitting.

Buying Guide

When buying a replacement derailleur hanger, matching the hanger pattern to your frame is the top priority — look for the Wheels Manufacturing part number or OEM stamping on the old hanger. Material and manufacturing method matter too: CNC-machined aluminum hangers like the Dropout 133 provide consistent geometry and predictable deformation to protect the derailleur in a crash. Keep a spare hanger in your toolbox or travel kit if you ride often or race. A correctly fitted hanger plus a hanger alignment gauge will keep shifting precise and help prolong the life of your drivetrain.
