Product Details

Overview & Technology

Wheels Manufacturing Dropout 5 is a direct replacement derailleur hanger designed for Gary Fisher and compatible Trek road frames from 2002–2003. Engineered to restore factory alignment and protect your frame, this hanger replicates the OEM geometry so your rear derailleur returns to the correct position after a crash or hardware failure. Manufacture and finish: The hanger is precision CNC-machined from 6061-T6 aluminum and finished with a hard black anodize to resist corrosion and wear. Its precise mounting points and tolerance-controlled profile ensure consistent derailleur alignment and long-term durability under road riding loads.

Key Features & Benefits

Durable construction: CNC-machined 6061-T6 aluminum provides the stiffness to maintain derailleur alignment while remaining light — a reliable choice for road use where precise shifting matters. The anodized coating helps prevent galvanic corrosion between the hanger and frame hardware. Real-world benefits: Replacing a bent or damaged hanger with a Dropout 5 restores crisp shifting, reduces chain drop risk, and protects the frame and derailleur in a future impact. Because it mirrors OEM geometry, you avoid time-consuming derailleur re-indexing and alignment hassles after installation.

Fit, Installation & Compatibility

This Dropout 5 is specified for Gary Fisher and similar Trek road frames from the 2002–2003 era. Before purchasing, compare the shape and mounting hole spacing with your existing hanger or OEM part. The product number (270378) / manufacturer part # DROPOUT-5 corresponds to Wheels Manufacturing's listing for this fitment. Installation is straightforward for most mechanics: remove the old hanger, align the new hanger to the frame's dropout threads or bosses, and torque the mounting fastener to the frame manufacturer's recommended value. If your frame used a specific bolt or adapter, verify whether your original hardware is required — many users re-use OEM bolts, while some setups accept standard stainless bolts.

Who This Hanger Is For

This hanger is ideal for riders restoring or maintaining Gary Fisher/Trek road bikes from the early 2000s, vintage-road enthusiasts, and shop technicians who need an accurate replacement that matches OEM geometry. It’s perfect if you want to get a vintage frame back on the road with reliable, factory-like shifting. Also useful as a spare part for racers and commuters who want a ready replacement at the shop or in the toolbox. Because derailleur hangers are sacrificial parts, keeping a Dropout 5 on hand prevents long delays when the unexpected happens during a ride or race.

Frequently Asked Questions

Will this hanger fit my Trek or Gary Fisher frame?

This Dropout 5 is made to match the OEM hanger used on Gary Fisher and similar Trek road frames from 2002–2003. Compare the shape and mounting hole pattern to your existing hanger or OEM part number to confirm fit. If in doubt, send a photo to your local shop or our support team for verification.

What material is the Dropout 5 made from?

The hanger is CNC-machined from 6061-T6 aluminum and finished with a hard black anodize. This combination provides a stiff, lightweight replacement that resists corrosion while protecting your frame and derailleur.

Does the hanger include mounting hardware?

Mounting hardware requirements vary by frame. Many riders reuse the OEM bolt; some frames require a specific adapter or fastener. Check your original hardware first — if you need replacement bolts, we can recommend compatible stainless steel mounting screws.

Can I install this hanger myself?

Yes — installation is straightforward for anyone comfortable with basic bike maintenance. Remove the wheel and old hanger, mount the new hanger to the dropout, and torque the bolt to the frame manufacturer's spec. After installation, check derailleur alignment and indexing; a quick tune-up may be necessary.

What if the new hanger doesn't perfectly align the derailleur?

While Dropout 5 is designed to mirror OEM geometry, minor fine-tuning of the derailleur may be needed. If alignment issues persist, consider using a derailleur hanger alignment tool or taking the bike to a pro mechanic to ensure the hanger and derailleur are correctly positioned.

Is this hanger suitable for modern wide-range drivetrains?

The hanger restores the original mounting point and should work with most modern derailleurs, but compatibility depends on derailleur design and cage length. Verify that your derailleur's B-screw and capacity are compatible with your cassette range before upgrading.

Buying Guide

When buying a replacement derailleur hanger, accuracy of fit is paramount — even small differences in mounting geometry affect shifting. Start by identifying your frame model and year, then compare the physical shape and bolt spacing of the OEM hanger to the replacement. Choose a hanger machined from 6061-T6 aluminum with a corrosion-resistant finish for the best balance of strength, weight, and longevity. Keep a spare hanger if you own a vintage or commuter frame; hangers are sacrificial parts designed to bend or break to protect the frame and derailleur. If you’re unsure, photograph your current hanger in place and consult the manufacturer or a bike mechanic to confirm compatibility before you buy.
