Product Details

Overview & Technology

Wheels Manufacturing DROPOUT-424 is a precision CNC-machined derailleur hanger engineered as a direct replacement for Cannondale Slate and SuperX 2018 frames that use the Cannondale DM dropout interface. Machined from high-grade 6061 aluminum, this hanger is bead- and tolerance-controlled to maintain accurate derailleur positioning and shift performance after installation. The hanger receives a durable black anodized finish that protects the alloy from corrosion and abrasion while keeping contact surfaces true. The part ships light (0.1 lb) and compact, yet is designed to be the intentional sacrificial failure point that saves expensive frame and drivetrain components in a crash.

Key Features & Benefits

CNC-machined 6061 aluminum body provides a stiff, lightweight platform that resists bending under pedaling load and preserves shift indexing. The precise machining ensures the derailleur hanger alignment is consistent with factory specifications for reliable performance. • Black anodized finish: Adds corrosion resistance and reduces galling at the mounting interface. • M3x10SH mounting: Uses the supplied M3x10SH fastener pattern found on Cannondale DM dropouts for a secure, OEM-style attachment. • Sized for Cannondale Slate & SuperX 2018: Guaranteed fit for the listed frames — ideal spare or repair part.

Fit, Compatibility & Installation

This hanger is specifically produced for the Cannondale DM style dropout found on the Cannondale Slate and SuperX 2018 frames. Confirm your frame's dropout style and part orientation before purchase — this is not a universal hanger and is made to match the OEM geometry and hole pattern. Installation is straightforward: align the hanger with the frame dropout and secure using the M3x10SH fastener. Torque the screw to the frame manufacturer's recommended specification (typically low torque for small M3 fasteners) and check derailleur alignment with a hanger alignment gauge after installation if available.

Who This Hanger Is For

If you own a Cannondale Slate or SuperX 2018 and need a reliable, OEM-fit replacement — whether from damage, wear, or for keeping a spare in your kit — the DROPOUT-424 is made for you. Gravel and cyclocross riders who value precise shifting and want a light, durable spare will appreciate the part's fit and finish. Mechanics and shop techs will also value the repeatability of a CNC-machined hanger when performing drivetrain repairs or when re-aligning derailleurs after crashes. Keep one in your spare-parts stash to minimize downtime on race day or during long gravel rides.

Frequently Asked Questions

Will this hanger fit my Cannondale frame?

DROPOUT-424 is made for the Cannondale DM dropout used on Slate and SuperX 2018 models. Confirm your frame year and dropout style — if your frame uses a different hanger pattern or non-DM dropout, this part will not fit.

Does the hanger come with the M3x10SH screw?

This product references the M3x10SH mounting interface. Check the product packaging or listings for included hardware; many Wheels Manufacturing hangers are sold with the appropriate mounting screw, but some dealers list the hanger separately. If unsure, contact Forest Bikes or include a spare M3 screw in your order.

Can I bend this hanger back into alignment after a crash?

While 6061 aluminum hangers can sometimes be straightened, DROPOUT-424 is designed as a replaceable, sacrificial part. If the hanger is bent, replacement is recommended to ensure precise derailleur alignment and long-term drivetrain performance.

How do I check alignment after installing the hanger?

After installing, shift through the gears and check indexing. For best results, use a derailleur hanger alignment gauge to confirm the hanger is true relative to the wheel. Small deviations can cause poor shifting or chain rub.

Is this hanger compatible with SRAM and Shimano derailleurs?

Yes — the hanger position is independent of derailleur brand. DROPOUT-424 provides the correct mounting geometry for either SRAM or Shimano rear derailleurs provided they are compatible with your drivetrain speed and cassette.

What if I need help identifying my hanger model?

If you're unsure, send photos of your dropout area to Forest Bikes customer service or compare measurements to the Wheels Manufacturing compatibility charts. Provide frame model and year to speed up identification.

Buying Guide

When replacing a derailleur hanger, prioritize exact-fit parts made to the OEM dropout profile. Hangers are small but critical: misalignment can cause poor shifting, chain drop, and drivetrain wear. Select a hanger that lists your specific frame model and year (in this case Cannondale Slate and SuperX 2018 with the Cannondale DM system). Look for materials and finishes that balance stiffness and sacrificial behavior — 6061 aluminum with an anodized surface gives precise alignment and corrosion protection while allowing the hanger to break instead of your frame in a crash. Keep a spare hanger in your toolkit if you ride gravel or race cyclocross frequently.
