Product Details

Overview & Technology

Wheels Manufacturing Dropout 163 is a precision replacement derailleur hanger engineered to restore factory alignment and shifting performance on compatible Cervélo road frames. Built as a direct-fit OEM-style part, this hanger replicates the original dropout geometry so your derailleur rides in the correct plane and keeps the drivetrain running smooth. The hanger is CNC-machined from a high-strength aluminum alloy and finished with a corrosion-resistant coating to stand up to road grime and wet-weather use. Precision machining and tight tolerances ensure consistent derailleur placement, while the compact, lightweight design preserves frame aesthetics and ride weight.

Key Features

Durable construction: CNC-machined aluminum alloy with a corrosion-resistant finish for long life and reliable performance. The robust design protects the frame by offering a replaceable sacrificial part in the event of a crash or impact. OEM-style fit and function: Built to match Cervélo's dropout geometry (#163), this hanger restores proper derailleur alignment for crisp shifting. Shipping size and weight are minimal for fast dispatch: 3" x 3" x 0.3", 0.02 lb.

Fit & Compatibility

This part is catalogued as #163 (DROPOUT-163) and is specifically matched to select Cervélo road frames. Confirm compatibility by checking your frame’s hanger number or comparing the old hanger to the Dropout 163 shape before purchase. Installation is straightforward for any mechanic familiar with rear derailleur mounts — the hanger mounts to the frame using the original hardware location. If your bike uses a replaceable hanger plate or adapter, verify that the mounting interface matches Cervélo’s design for a correct fit.

Who It's For

This hanger is ideal for Cervélo road riders, mechanics, and shops needing an exact replacement for a damaged or bent derailleur hanger. Whether you’re repairing a bike after a tip-over or maintaining drivetrain precision, the Dropout 163 gives a cost-effective way to restore OEM alignment. Enthusiasts who value quick, reliable fixes and shops that keep common Cervélo hangers in stock will find this part indispensable. It’s also useful for riders doing home repairs who want a straightforward swap to get back on the road fast.

Frequently Asked Questions

How do I know if Dropout 163 fits my Cervélo frame?

Match the hanger number stamped on your old hanger or check your frame documentation for compatibility with #163. You can also compare the shape and mounting bolt pattern of your current hanger to photos of the Dropout 163 to confirm fit.

What tools are required to install this derailleur hanger?

Installation typically requires basic tools: a set of hex/Allen keys or Torx bits to remove the old hanger and torque the mounting fastener, plus a torque wrench to ensure correct clamp force if specified by the frame manufacturer. A derailleur alignment gauge can help verify straightness after installation.

Is hardware included with the Dropout 163?

Hardware inclusion varies by supplier. Wheels Manufacturing hangers commonly ship as the hanger itself; check the product listing or packaging for included bolts. If hardware isn’t included, reuse the original mounting bolt if undamaged or source a replacement from Wheels Manufacturing or your dealer.

Can a bent hanger be straightened or should I replace it?

Minor bends can sometimes be corrected with a derailleur hanger alignment tool, but repeated bending weakens the metal. Because the hanger is a sacrificial part designed to protect the frame, replacement is recommended for reliable alignment and long-term safety.

Does this hanger work with modern 12-speed drivetrains?

Yes — hanger compatibility is based on frame geometry rather than drivetrain speed. As long as the hanger matches your Cervélo frame’s mounting and alignment, it will support modern 11- and 12-speed derailleurs, including Shimano and SRAM road groupsets.

Buying Guide

When buying a replacement derailleur hanger, prioritize correct fit over brand. Confirm the hanger number or compare mounting holes and overall shape to avoid returns — derailleur hangers are frame-specific and rarely interchangeable across different frame designs. Choose a hanger manufactured from a durable, machined material with a corrosion-resistant finish and, if possible, purchase from a reputable maker like Wheels Manufacturing. Keep a spare on hand if you ride frequently or travel; a broken hanger is a common and easily solved roadside failure.
