Product Details

Overview & Technology

DROPOUT-295 is a direct-fit replacement derailleur hanger machined from 6061-T6 aluminum and finished with a hard black anodize for corrosion resistance and consistent alignment. Built by Wheels Manufacturing to match Cannondale Part # E123007-1 R3 (KP381), this hanger is designed to interface with MAXLE thru-axles using an M12 x 1.75 thread pitch. Why CNC and 6061 matter: the CNC process ensures tight tolerances and clean mounting faces so the derailleur sits true, while 6061-T6 offers a proven strength-to-weight balance—stiff where it needs to be but sacrificial to protect your expensive frame and drivetrain in a crash.

Key Features & Benefits

Durable construction: CNC-machined 6061 aluminum provides reliable strength and repeatable geometry, while the black anodized finish resists chips and corrosion from mud and salt. • OEM equivalence: Matches Cannondale Part # E123007-1 R3 (KP381) for a true factory fit. • Thru-axle compatibility: Engineered for MAXLE systems with M12 x 1.75 thread pitch. • Replaceable safety: Acts as a designed sacrificial part to protect your frame and derailleur during impacts.

Fit, Installation & Compatibility

This hanger is made specifically for Cannondale frames that use the E123007-1 R3 style dropout and a MAXLE M12 x 1.75 thru-axle. Check your frame’s OEM part number or compare the mounting shape to ensure a match. The DROPOUT-295 bolts into the frame in the same orientation as the original and accepts standard rear derailleurs from Shimano, SRAM and other manufacturers. Installation notes: the hanger ships without axle or derailleur hardware. Use proper torque on the mounting fasteners (follow frame maker specs), keep threads clean, and apply a light anti-seize or threadlocker as recommended for your frame. If alignment is off after install, a hanger alignment gauge can be used to fine-tune straightness.

Who This Hanger Is For

The DROPOUT-295 is for mountain riders who own Cannondale frames that use the R3-style dropout and MAXLE M12 thru-axles. It's an essential spare for trail riders, bikepackers, and anyone who wants to keep a proven replacement on hand for faster roadside repairs. Ideal user: Cyclists who value OEM-fit replacements, want a durable aftermarket hanger that matches factory geometry, or need a low-weight, easily replaceable sacrificial part to protect their frame and drivetrain.

Frequently Asked Questions

Will DROPOUT-295 fit my Cannondale frame?

DROPOUT-295 is designed to match Cannondale Part # E123007-1 R3 (KP381). Confirm your frame uses that OEM hanger style or compare the mounting shape and M12 Maxle thread pitch before purchasing. If you’re unsure, provide your bike model and year to our team for verification.

Does the hanger come with mounting bolts or axle hardware?

No—this product ships as the hanger only. Use your original mounting bolts or fitment hardware from the frame manufacturer. Replace bolts if they’re damaged and follow Cannondale torque specs and anti-seize/threadlocker recommendations.

Can I straighten a bent DROPOUT-295 or should I replace it?

Minor bends can sometimes be realigned with a hanger alignment tool, but because this hanger is designed to be sacrificial and precise, replacement is recommended if the damage affects derailleur indexing or if the hanger has cracks. Replacing ensures perfect geometry and safer shifting.

Is this compatible with Shimano and SRAM derailleurs?

Yes. The DROPOUT-295 provides the standard derailleur mounting interface used by Shimano, SRAM and most aftermarket derailleurs. Ensure the hanger alignment is correct for crisp shifting.

What thread pitch do I need to know for this hanger?

This hanger is built for MAXLE axles with an M12 x 1.75 thread pitch. Verify your thru-axle specs—if your axle uses a different pitch or diameter, this hanger will not seat correctly.

How do I maintain the hanger to prevent corrosion or seizing?

Keep threads clean and lightly greased or use anti-seize on steel-to-aluminum contact. After riding in wet or salty conditions, rinse and dry the area and inspect the hanger for nicks or bending. Re-anodize isn’t practical—replace if the finish is heavily damaged.

Buying Guide

When buying a replacement derailleur hanger, the two critical checks are frame compatibility and axle thread pitch. Start by matching your bike’s OEM hanger number or comparing the shape to the DROPOUT-295. Confirm your rear axle is a MAXLE-style M12 x 1.75 thru-axle—mismatched axle threads or hanger geometry will prevent correct installation. Choose CNC-machined 6061 hangers for a balance of light weight, repeatable geometry and predictable failure behavior: they protect your frame by bending or breaking in a controlled way. Keep a spare on long rides or tours—swapping a hanger is typically faster than realigning a severely bent one and will get you back on the trail sooner.
