Product Details

Overview & Technology

Wheels Manufacturing DROPOUT-337 is a precision replacement derailleur hanger engineered to restore perfect drivetrain alignment on compatible Norco frames. CNC-machined from high-strength aluminum, this hanger reproduces OEM geometry so your rear derailleur sits exactly where it should for crisp, consistent shifting. This hanger is made to be a sacrificial component — it bends or breaks on impact to protect the frame and derailleur in a crash. A hard-anodized finish improves corrosion resistance and reduces wear from the derailleur mounting interface, extending usable life while remaining lightweight.

Key Features & Construction

The DROPOUT-337 is crafted from 6061-T6 grade aluminum using CNC machining to hold tight tolerances across the mounting face and derailleur boss. That accuracy ensures the hanger returns your derailleur to OEM placement for reliable shifting and chain retention. Other practical features include a corrosion-resistant anodized surface, compact low-profile shape to minimize impacts, and a precisely located mounting hole for a stable connection to the frame. The part ships light — 0.1 lb — and matches the original fit and function for the listed Norco models.

Fit, Compatibility & Installation

DROPOUT-337 is a direct replacement designed specifically for a range of Norco frames: Fluid FS MKIII (2019), Optic Carbon (2018), Sasquatch FAT (2016–2017), Sight Alloy (2017–2018), Sight Carbon (2017–2018), Torrent Alloy FS (2017), and Torrent HT (2016–2017). Check your frame's existing hanger shape and part number to confirm compatibility before ordering. Installation is straightforward: remove the old hanger and bolt the new unit into the same location using the original mounting hardware where possible. Tighten to the frame manufacturer's torque specification and check derailleur alignment after mounting. Carrying a spare hanger on longer rides is recommended — they’re light, cheap, and can save you a walk home.

Who This Hanger Is For

This replacement hanger is for mountain bikers riding compatible Norco models who need an exact-fit spare or a crash-replacement part. It's ideal for trail riders, bike park regulars, and anyone who wants to keep their drivetrain shifting precisely after an impact. Mechanics and home wrenches will appreciate the OEM-correct geometry and durable construction that makes repairs quick and predictable. If you own one of the listed Norco frames, DROPOUT-337 is the recommended replacement to restore frame-specific derailleur positioning.

Frequently Asked Questions

Which Norco models does DROPOUT-337 fit?

DROPOUT-337 is made for specific Norco frames: Fluid FS MKIII (2019), Optic Carbon (2018), Sasquatch FAT (2016–2017), Sight Alloy (2017–2018), Sight Carbon (2017–2018), Torrent Alloy FS (2017), and Torrent HT (2016–2017). Verify the hanger shape and part number on your bike before buying.

Is this hanger identical to the OEM part?

Yes — Wheels Manufacturing reproduces OEM geometry with CNC precision so the DROPOUT-337 returns the derailleur to the intended position. That ensures the same shifting performance as the original part when installed correctly.

Does the hanger come with mounting hardware?

Hardware inclusion can vary by supplier. Check the product notes or your order — if mounting bolts are not included, reuse the original bolts from your frame or purchase appropriate stainless hardware sized for your frame's hanger mount.

How do I install and align the new hanger?

Remove the damaged hanger, fit the DROPOUT-337 into the same mounting points, and torque bolts to the frame manufacturer's specification. After installation, check derailleur indexing and fine-tune the high/low limit screws and cable tension as needed to restore smooth shifting.

Should I carry a spare hanger on trail rides?

Yes. Derailleur hangers are inexpensive and lightweight — carrying a spare can save a ride if your hanger bends or breaks. Store it with a small multi-tool and bolt so you can swap it roadside.

What material is the hanger made from?

This hanger is CNC-machined from high-strength 6061‑T6 aluminum and finished with a corrosion-resistant anodize. The material balances light weight with the controlled failure behavior you want from a sacrificial hanger.

Buying Guide

When replacing a derailleur hanger, compatibility is the top priority: match the hanger shape and mounting hole locations to your frame model and year. Use the manufacturer or hanger part number where possible — DROPOUT-337 is specifically patterned for the Norco frames listed above. If you're unsure, remove the old hanger and compare it visually to product images before ordering. Material and construction matter, too. CNC‑machined 6061‑T6 aluminum hangers like this one offer precise geometry and controlled sacrificial behavior. Finally, keep a spare on long rides — hangers are inexpensive insurance that can turn a potential walk into a continued ride in minutes.
