Product Details

Overview & technology

Wheels Manufacturing Dropout 180 (DROPOUT-180) is a purpose-built replacement derailleur hanger made for select Scott frames. Part number 270448 provides an exact-fit, OEM-style mounting point engineered to restore your drivetrain geometry after a crash or bent hanger. Lightweight and compact — shipping dims 3" x 2" x 0.3", weight ~0.02 lb — it slips into place without altering frame clearance or chainline. This hanger is precision CNC-machined from a heat-treated aluminum alloy, then finished with a hard anodized coating to resist corrosion and abrasion. The manufacturing tolerances are held tight so the derailleur's B-tension and lateral alignment match factory specifications, helping you get crisp, consistent shifts faster than guess-and-bend repairs.

Key features & benefits

Designed for repeatable alignment: the Dropout 180 reproduces the original hanger shape and mount locations so every replacement brings your derailleur back to spec. That means fewer indexing issues and reduced chain rub. Real-world benefits include: • Quick field or workshop swap to get you riding again after damage. • Durable anodized finish resists road grime and weather. • Minimal weight penalty while providing robust mounting for modern derailleurs.

Fit, compatibility & installation

This hanger is listed as Wheels Manufacturing #180 and marked for Scott frames — check your frame's hanger shape against photos or measure mount hole spacing to confirm. The Dropout 180 is sold as the hanger only; it uses your frame's original mounting bolt and hardware. If your frame supplied a captive or pressed-in screw, you may need to reuse that fastener or source the correct replacement from Scott or a bike shop. Installation is straightforward: remove the bent hanger, clean the mounting surface, and seat the replacement. Use a torque wrench to tighten to the frame manufacturer's spec and check derailleur alignment with a hanger alignment gauge. If you ride frequently in rough terrain, inspect the hanger after any impact — replacing a bent hanger quickly prevents drivetrain damage.

Who it's for

Ideal for road cyclists and club racers who own compatible Scott frames and want a fast, exact-fit replacement after a crash. It's also a smart spare for mechanics and home wrenches who carry common Scott hangers for on-the-fly repairs. Whether you commute, train, or race, keeping a Dropout 180 in your parts drawer saves downtime — a simple, light, and reliable replacement that gets shifting back to factory behavior.

Frequently Asked Questions

How do I know if the Dropout 180 fits my Scott frame?

Compare the hanger shape and mounting hole locations to your existing hanger or photos from the manufacturer. Wheels Manufacturing #180 is specified for certain Scott models — if you have any doubt, bring your old hanger to a shop or contact Forest Bikes with your bike model and year for confirmation.

Is mounting hardware included with this hanger?

No. The Dropout 180 is sold as the hanger only and typically uses the original frame mounting bolt. If your frame's bolt was lost or damaged, source the correct fastener from Scott or a bike shop to match thread size and length.

Can I straighten a bent hanger instead of replacing it?

Minor bends can sometimes be realigned with a hanger alignment tool, but repeated bending weakens the metal and risks misalignment. Replacing with an exact-fit Dropout 180 ensures factory geometry and more reliable shifting — it's the recommended solution after an impact.

What material is this hanger made from?

The hanger is CNC-machined from a heat-treated aluminum alloy and finished with a hard anodized coating for durability and corrosion resistance. That construction balances light weight with the necessary strength to hold modern derailleurs.

Do I need a professional to install this hanger?

A competent home mechanic can swap the hanger with basic tools and a torque wrench. For best results and to verify derailleur alignment, use a hanger alignment gauge or visit a shop to ensure precise indexing and avoid drivetrain issues.

How quickly will a replacement hanger fix shifting issues?

If shifting problems are due to a bent hanger, installing the Dropout 180 typically restores correct alignment and clears indexing problems immediately. If issues persist, check derailleur limit screws, cable tension, and derailleur hanger alignment with a gauge.

Buying Guide

When choosing a replacement derailleur hanger, compatibility is the primary concern. Match the hanger number or compare the physical shape and mounting hole spacing with your damaged part. Buying a hanger from a reputable maker like Wheels Manufacturing gives you precise CNC tolerances and corrosion-resistant finishing that help maintain factory shift geometry. Also consider whether you need to keep a spare on hand: riders who travel, race, or mountain-bike regularly benefit from carrying a light replacement hanger to minimize downtime after an impact. If unsure, contact Forest Bikes with your frame model and year — our techs can verify fitment for you.
