The Wheels Mfg Derailleur Hanger #5 is a high-performance, CNC-machined replacement for one of the most widely used hanger designs in the mountain bike world. While original equipment (OEM) hangers are typically made from soft, cast aluminium that can bend under the high chain tension of modern 1x drivetrains, the #5 is carved from a solid block of 6061-T6 aircraft-grade aluminium. This added rigidity ensures your derailleur remains perfectly aligned, resulting in snappier shifting and better protection for your frame during minor impacts.
Manufactured in Colorado, USA, this "2-bolt" style hanger is a staple for mechanics restoring the shifting performance of mid-2000s and early-2010s mountain bikes. Because it is machined to much tighter tolerances than cast parts, it effectively eliminates the "mushy" shifting feel often found on older frames that have suffered from years of vibration and trail abuse.
CNC Machined 6061-T6 Aluminium: Provides superior stiffness and strength compared to standard cast hangers, keeping your shifting indexed even on rough terrain.
Hard Anodised Black Finish: Features a durable, corrosion-resistant surface that stands up to aggressive degreasers and harsh trail conditions.
Two-Bolt Attachment: Mounts securely to the frame using two M4x8 Flat Head Screws (included), creating a rock-solid interface that won't pivot or loosen.
Professional Alignment: Machined to exact workshop tolerances, ensuring your derailleur sits perfectly parallel to your cassette for an optimal chain line.
Made in the USA: Produced in Wheels Manufacturing’s Colorado facility to exacting quality standards.
