Product Details

Overview & Technology

Wheels Manufacturing Dropout 106 is a precision replacement derailleur hanger engineered to match the original Look #106 dropout interface. Machined from high-strength aluminum alloy, this hanger replicates OEM geometry so your derailleur alignment and shifting feel are restored without compromise. The part (Manufacturer Part #: DROPOUT-106, Product No: 270418) is designed as a sacrificial component — it takes the impact in a crash to protect your frame and derailleur. Its lightweight construction (approx. 0.05 lb) keeps mass to a minimum while delivering the stiffness needed for accurate shifting under load.

Key Features

Durable CNC-machined construction: The Dropout 106 is CNC cut from billet aluminum for tight tolerances and consistent fit. That precision reduces slack between hanger and frame, maintaining crisp shifting and drivetrain performance. Why it matters: A true OEM-spec hanger maintains derailleur alignment and prevents indexing issues — a small part that makes a big difference on every ride. • CNC-machined aluminum alloy for strength and light weight • Exact replacement for Look #106 interface • Lightweight: shipping weight ~0.05 lb and compact dimensions • Packaged for easy postage and quick replacement

Fit & Compatibility

This hanger is specifically made to match the Look frame dropout standard labeled as #106. It is intended as a direct-fit OEM-style replacement for Look frames that originally shipped with the #106 hanger; check your frame documentation or current hanger stamping to confirm the number before ordering. Because derailleur hangers are frame-specific, the Dropout 106 will not fit other brands or Look variations that use a different hanger shape. If you’re unsure, compare the part number on your existing hanger or contact our support with your frame model and year for fast verification.

Who This Hanger Is For

Road riders who own a Look frame that requires the #106 hanger will find this part essential. It’s ideal as a spare to carry on long rides or to keep in your workshop for fast post-crash repairs. Mechanics and home wrenchers also appreciate the repeatable fit and the peace of mind of using a purpose-made replacement part. If you race, commute, or tour on a Look road frame, a lightweight, exact-fit hanger like the Dropout 106 ensures minimal drivetrain fuss and helps prevent frame damage in impacts — a small investment that saves bigger repairs down the road.

Frequently Asked Questions

How do I know if this hanger fits my frame?

Check the stamping or printed number on your current derailleur hanger — if it shows #106 it’s the correct match. If you don’t have the old hanger, provide your Look frame model and year to our support team and we’ll verify compatibility.

Does the Dropout 106 include mounting hardware?

This listing is for the hanger body itself. Mounting bolts may be reused from your original hanger; if you need replacement hardware, we can recommend the correct bolts and hardware kit based on your frame.

Can I use this hanger with modern 11- or 12-speed drivetrains?

Yes — since this hanger reproduces OEM geometry, it will support modern road derailleurs (including 11- and 12-speed systems) as long as the frame’s derailleur hanger standard is #106 and the derailleur itself is compatible with your cassette and chain.

What if the hanger becomes bent after a crash?

Derailleur hangers are designed to be sacrificial; a bent hanger should be replaced rather than continually bent back and reused. Replacing the hanger preserves drivetrain alignment and prevents further damage to the derailleur or frame.

Do I need a hanger alignment tool to install this?

Installation typically involves removing the damaged hanger and bolting the new one in place. After installation, a hanger alignment check with a dedicated tool is recommended to ensure perfect derailleur alignment and optimal shifting performance.

What are the shipping dimensions and weight for this part?

The product ships in compact packaging measuring approximately 3" x 3" x 0.3" and weighs about 0.05 lb, making it an inexpensive, quick-to-ship spare for your toolkit.

Buying Guide

When buying a derailleur hanger, the most important factor is compatibility — hangers are frame-specific parts, so match the hanger number or frame model exactly. Prefer CNC-machined alloy replacements for consistent geometry and reliable shifting; they deliver OEM-like performance at an affordable price. Always keep a spare hanger in your toolkit or workshop; replacing a damaged hanger is a quick repair that prevents expensive derailleur or frame damage. If in doubt, contact Forest Bikes with your frame details and we’ll confirm the correct Dropout number for you.
