Product Details

Overview & Technology

Dropout 274 from Wheels Manufacturing is a direct-replacement derailleur hanger engineered for Norco frames. CNC-machined from high-strength aluminum, this hanger restores correct derailleur geometry after damage or wear, protecting your frame and keeping shifting precise. The part is typically produced from 6061-T6 aluminum with a corrosion-resistant finish for long life in wet, gritty mountain conditions. Its tight tolerances and accurate hole locations ensure repeatable alignment and consistent shifting performance when installed to factory torque specs.

Key Features

Precision fit and construction: CNC machining gives accurate B-tension and hanger angle so your derailleur tracks the cassette correctly. The lightweight design (approx. 0.03 lb) keeps mass down without sacrificing strength. Real-world benefits include quicker, easier wheel and drivetrain service, minimized risk of frame damage in a crash, and the ability to return shifting to OEM spec. The compact shipping size (2" x 1" x 0.3") makes it a handy spare to carry on rides or store in a workshop.

Fit, Compatibility & Installation

This Dropout 274 is identified as Norco-specific (#274) and matches the OEM mounting points and hole pattern for direct bolt-on replacement. Verify the manufacturer part number (DROPOUT-274 / Wheels Manufacturing part 270767) against your Norco frame's hanger number before purchase. Installation is straightforward: remove the rear wheel, unbolt the damaged hanger, clean the mating surface, and fit the replacement using the original hardware or the correct-size bolts (use threadlocker if specified by the frame manufacturer). Check hanger alignment with a derailleur hanger alignment gauge and torque bolts to your frame maker's recommendation.

Who This Hanger Is For

Mountain bikers who ride Norco frames — whether trail, all-mountain, or enduro — will want this Dropout 274 as an OEM-correct replacement or spare. It's ideal for riders who frequently service their drivetrain or who want a lightweight, reliable spare to carry on multi-day rides. Mechanics and home-wrenchers will appreciate the accurate machining that speeds setup and helps avoid shifting issues caused by bent or missing hangers. If you own a Norco and experience poor indexing, chain drops, or unexplained drivetrain noise, replacing the hanger with the correct Dropout 274 is often the first and most effective fix.

Frequently Asked Questions

How do I know this hanger fits my Norco frame?

Compare the hanger number on your frame or the old hanger to #274. Wheels Manufacturing Dropout 274 is made to match Norco's OEM hole pattern and geometry. If unsure, check your frame documentation or contact Forest Bikes with your Norco model and year.

Does this hanger include mounting bolts or hardware?

The Dropout 274 is typically sold as the hanger only and does not always include bolts. Use your original frame hardware or purchase correct-size replacement bolts separately. If hardware is critical, confirm inclusion at checkout or add suitable bolts to your order.

Can I ride with a bent hanger before replacing it?

Riding with a bent hanger risks further drivetrain damage and poor shifting. It’s best to replace or realign the hanger before riding long or technical trails. Carrying a spare like Dropout 274 is recommended for Norco riders to avoid being stranded.

What material is the hanger made from?

Wheels Manufacturing hangers like the Dropout 274 are CNC-machined from high-strength aluminum (commonly 6061-T6) with a corrosion-resistant finish. That gives a strong, lightweight part that withstands normal trail abuse.

Do I need a special tool to install or align the hanger?

Basic installation requires standard hex or torx tools for the mounting bolts. For best shifting results, use a derailleur hanger alignment gauge to check and correct alignment relative to the wheel. Many bike shops will perform alignment if you don’t have the tool.

Is this an original replacement part or aftermarket?

This is an aftermarket replacement manufactured by Wheels Manufacturing (part #270767 / DROPOUT-274) designed to match Norco's OEM dimensions and performance while offering durable CNC precision.

Buying Guide

When replacing a derailleur hanger, prioritize exact-fit parts identified by your frame maker's hanger number. Wheels Manufacturing offers many model-specific hangers like the Dropout 274 to match Norco geometry and mounting points. Choosing a CNC-machined aluminum hanger gives a balance of light weight and strength needed for mountain riding. Also consider whether you need replacement hardware and whether you'll carry a spare on rides. If you frequently ride remote trails, a spare hanger and a few bolts in your toolkit can save a long walk back to the car or shop.
