Replacing a rear derailleur hanger can be a narrow, specification-led choice: when the stated bike application, material, color, and approximate weight line up, a small listed-price difference may be the deciding detail. Here, both cycling accessories are black, new bike rear derailleur hangers made from aluminum alloy and described at about 40g. Both are also described for the Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout application.
Quick verdict
Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories if your priority is the lower listed price. It is listed at USD 19.31, while the other option is listed at USD 19.60-a $0.29 spread.
Choose Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy if you prefer a title that directly calls out its aluminum-alloy construction. Its listed specifications otherwise align with the other hanger: black color, about 40g weight, and bike rear derailleur hanger part type.

Where each option wins
Lower listed price: Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
The $19.31 listed price is the clearest reason to select this version. Its title also foregrounds the approximately 40g weight, which matches the product description. Because the material, black color, part type, and stated Scott #277544 Addict RC 2020 application align across both choices, this is the straightforward pick when price is the deciding factor.
Material-forward title: Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy
This option earns its place for shoppers who want the title itself to explicitly name aluminum alloy. That material is also stated in the description, alongside the black finish and about 40g weight. At USD 19.60, it sits at the top of this two-item price range, so its appeal is primarily the construction-focused naming rather than a stated specification advantage.
Product notes
Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy
Pick this rear mech hanger when an aluminum-alloy label in the product title is the detail you want surfaced immediately. The description matches that focus, identifying aluminum alloy construction, a black color, and a weight of about 40g. It is also identified as a bike rear derailleur hanger for the Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout application. That makes the stated application and part type easy to connect with the title's material emphasis. Its limitation in this head-to-head is the USD 19.60 listed price: the competing hanger carries the same stated material, color, approximate weight, and application at a lower listed price.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
This is the practical choice for a shopper comparing the two listed prices first. At USD 19.31, it is the lower-priced option, and its title specifically calls out the about-40g weight. The description supports that weight, while also specifying aluminum alloy, black color, and the bike rear derailleur hanger part type. Its stated application is the same Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout noted for the other option. The limitation is simply that its longer title does not name aluminum alloy as directly as the competing title, even though aluminum alloy is included in its description.
Final choice by use case
- Choose the lower listed price: Go with Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories at USD 19.31.
- Choose the more material-specific title: Go with Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy at USD 19.60.
- Choose based on the shared stated application: Either option presents the same Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout application, black color, aluminum-alloy material, and approximately 40g weight.
