Product Details

Overview & Technology

Dropout 349 (Manufacturer Part #: DROPOUT-349, Product #: 271065) is a direct-replacement derailleur hanger manufactured by Wheels Manufacturing for select Pinarello road bike dropouts. CNC-machined from high-strength aluminum and finished with a corrosion-resistant anodize, this hanger delivers the dimensional accuracy required for smooth shifting and reliable drivetrain performance. The compact, precision-machined profile protects your frame and derailleur by taking the impact should a crash or wheel-out incident occur. At just a few grams in weight, the Dropout 349 balances durability and low mass while keeping the derailleur alignment true ride after ride.

Key Features & Benefits

The Dropout 349 is built from CNC-machined 6061-T6 aluminum with a hard-anodized finish for long-term wear resistance and corrosion protection. Precision machining ensures consistent hole spacing and surface flatness so your rear derailleur mounts cleanly and the hanger aligns with the cassette plane for crisp gear changes. Because it’s a replaceable hanger, the Dropout 349 spares your frame from damage in impacts and makes roadside or workshop repairs fast and simple. The lightweight construction keeps unsprung mass minimal while delivering the strength to withstand everyday riding stresses.

Fit & Compatibility

The Dropout 349 is designed specifically for Pinarello-style dropouts that use a removable hanger interface. Confirm compatibility by matching the part silhouette, mounting hole position and the OEM part number DROPOUT-349 with your frame documentation or the hanger currently on your bike. Because derailleur hangers vary between model years and sub-models, we recommend comparing the replacement hanger to your existing part before purchase. If in doubt, contact Forest Bikes with photos of the dropout and hanger or check the frame serial number with the bike manufacturer for exact fitment guidance.

Frequently Asked Questions

How do I know if Dropout 349 fits my Pinarello frame?

Compare the shape and mounting hole location of your current hanger to photos or the OEM part number. The safest method is to confirm the OEM part (DROPOUT-349) in your frame’s documentation or send photos of your dropout to Forest Bikes for verification.

Is mounting hardware included with the hanger?

Wheels Manufacturing typically supplies the hanger only; mounting bolts are not always included. Check your existing hardware for re-use or order the proper bolt separately if needed. If unsure, contact us and we’ll advise the correct bolt size for your frame.

Can a bent hanger be straightened instead of replaced?

Minor bends can sometimes be straightened with the right tools, but repeated straightening weakens the alloy and can lead to sudden failure. For safety and long-term alignment, replacement with a new Dropout 349 is the recommended option.

What tools are needed to install this hanger?

Basic tools include the correct-size hex or torx driver for your frame’s hanger bolt, a torque wrench to the manufacturer’s spec, and a derailleur alignment gauge if you want to verify alignment after installation.

How much does the Dropout 349 weigh and ship?

The product is extremely light—the item weight is approximately 0.01 lb. Shipping dimensions are compact at 2.25" x 1.25" x 0.5", making it a minimal addition to any parts order or spare-kit.

Why buy a Wheels Manufacturing hanger instead of OEM?

Wheels Manufacturing makes high-precision aftermarket hangers that match or exceed OEM tolerances, often at a lower cost and with consistent availability. Their CNC machining and anodized finishes provide a durable, reliable replacement for many frame-specific hangers.

Buying Guide

When buying a replacement derailleur hanger, measure twice: compare the part number, mounting hole placement, and silhouette to your existing hanger. Choose CNC-machined aluminum hangers for the best balance of lightweight performance and reliable strength; look for a protective anodized finish to resist corrosion. Keep a matched spare hanger in your saddlebag or toolkit—it's one of the simplest ways to avoid a day-ending mechanical. If you’re unsure about fitment, contact Forest Bikes with photos of your dropout and hanger so our fit experts can confirm compatibility before you buy.
