Dropout – No 59 Black: Your Ultimate Guide to Enhancing Bike Performance with This Essential Derailleur Hanger
In the world of cycling, every component plays a crucial role in ensuring a smooth, efficient, and enjoyable ride. Whether you’re a seasoned road cyclist tackling long distances or an adventurous gravel rider exploring off-the-beaten paths, maintaining your bike’s drivetrain is key to optimal performance. One often-overlooked but vital part is the rear derailleur hanger, and today, we’re diving deep into the Dropout – No 59 Black. This precision-engineered component has gained popularity among cyclists for its durability, compatibility, and ability to improve shifting precision. If you’re looking to upgrade or replace your bike’s hanger, this comprehensive guide will cover everything you need to know about the Dropout – No 59 Black, from its features and benefits to installation tips and where to find it.
What Is a Derailleur Hanger and Why Does It Matter?
Before we get into the specifics of the Dropout – No 59 Black, let’s start with the basics. A derailleur hanger, also known as a dropout hanger, is a small but critical piece of metal that attaches the rear derailleur to your bike’s frame. It’s designed to be the “weak link” in your drivetrain system—meaning it’s meant to bend or break in the event of an impact, protecting your more expensive frame and derailleur from damage.
Why is this important? In high-performance cycling, precise gear shifting can make the difference between a personal best and a frustrating ride. A worn-out or misaligned hanger can lead to poor shifting, chain drops, or even complete drivetrain failure. Replacing it with a high-quality option like the Dropout – No 59 Black ensures your bike stays in top shape, especially if you ride models from brands like BMC or other compatible frames.
Cyclists often encounter hanger issues after crashes, rough terrain, or simply from wear over time. According to industry experts, regularly inspecting and replacing your hanger can extend the life of your entire drivetrain. The Dropout – No 59 Black stands out because it’s crafted to meet the demands of modern 11- and 12-speed systems, making it a go-to choice for upgrades.
Key Features of the Dropout – No 59 Black
The Dropout – No 59 Black is more than just a replacement part—it’s engineered for performance. Let’s break down its standout features:
Material and Construction
Made from CNC-machined 6061 aluminum, this hanger offers exceptional strength and lightweight properties. The black anodized finish not only gives it a sleek, professional look but also provides corrosion resistance, ensuring it holds up against the elements during rainy rides or muddy trails. Unlike cheaper stamped steel hangers, the precision machining of the Dropout – No 59 Black results in tighter tolerances, which translates to better alignment and smoother shifting.
Direct Mount Compatibility
One of the highlights is its design for direct mount derailleurs. This means it works seamlessly with Shimano Shadow RD and Shadow RD+ models, as well as some Campagnolo derailleurs. No need for additional B-links or adapters— the Dropout – No 59 Black mounts directly to the frame, simplifying installation and reducing potential points of failure. This feature is particularly beneficial for bikes with 11- or 12-speed setups, where precise derailleur positioning is essential for crisp gear changes.
Attachment Mechanism
The hanger attaches to the frame’s rear dropout from the outside using a single M8 chainring bolt. This secure method ensures stability while allowing for easy wheel removal, which is a boon for roadside repairs or quick pit stops during races.

Compatibility: Which Bikes Does the Dropout – No 59 Black Fit?
Compatibility is a top concern when shopping for bike parts, and the Dropout – No 59 Black excels in this area. From the information gathered, it’s specifically designed for several BMC models from the 2020 lineup, including:
- MY20 Teammachine SLR01 and SLR02 Disc
- MY20 Roadmachine 01 and 02
- MY20 URS (gravel bikes)
- MY20 Timemachine Road 01
These are premium road and gravel bikes known for their aerodynamic designs and endurance capabilities. If you own one of these, the Dropout – No 59 Black is an OEM-level replacement that maintains the bike’s original performance standards.
Beyond BMC, versions from manufacturers like Wheels Manufacturing offer broader compatibility. Their Derailleur Hanger 59 (often referred to interchangeably as Dropout – No 59 Black) can fit various brands, but you’ll need to verify via the manufacturer’s fitment tool by selecting your bike’s brand, model, trim, and year. For instance, it’s commonly used on Felt bikes and others requiring a similar dropout design. If you’re unsure, contacting the manufacturer directly is recommended to avoid mismatches.

Benefits of Upgrading to the Dropout – No 59 Black

Cost-Effectiveness
Priced around $27.50 to $39 depending on the brand (Wheels Manufacturing vs. BMC), it’s an affordable upgrade that can prevent costly downtime. For the performance boost, it’s a smart investment for any serious rider.
In group rides or races, having reliable components like the Dropout – No 59 Black can give you that edge. Imagine gliding through gears effortlessly while others fiddle with adjustments.

Installing the Dropout – No 59 Black is straightforward for most home mechanics, but always consult your bike’s manual for specifics. Here’s a general high-level guide:
- Gather Tools: You’ll need an Allen key (typically 5mm for the M8 bolt), torque wrench, and possibly chain lube.
