A replacement rear mech hanger needs to match the bike application you are shopping for, but close-looking cycling accessories can make the final choice unnecessarily complicated. Here, both options are black, new bike rear derailleur hangers described for the Scott #277544 Addict RC 2020 SC-R-SW1-S Standard Mount Dropout 277544 carbon-frame bike. Their stated construction and approximate weight also align, leaving a straightforward listed-price decision.
Quick verdict
Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black if you want the lower listed price for the same core stated details: a black aluminum-alloy rear derailleur hanger, about 40g in weight, and one hanger in the package. It is listed at USD 18.83.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories carries the same stated black color, aluminum-alloy material, part type, bike application, and one-piece package. Its USD 21.01 price is USD 2.18 higher, so the main reason to select it is a preference for the title that explicitly calls out its about-40g weight.

Where each one wins
Rear Mech Hanger 1pcs Black wins on the lower listed price
The 1pcs Black version is the clear choice for a price-led purchase. It has the lower figure in this head-to-head while retaining the same shared essentials: black finish, aluminum-alloy construction, an about-40g weight, and the same Scott #277544 Addict RC 2020 application wording. Its title also makes the one-piece count immediately clear, matching the included single rear derailleur hanger.
Rear Mech Hanger About 40g wins for shoppers matching the weight-forward title
The About 40g version is the pick for anyone specifically matching an item identified by that wording. Its title foregrounds the approximate weight, while the description also identifies a black aluminum-alloy rear derailleur hanger intended for the same Scott #277544 Addict RC 2020 SC-R-SW1-S Standard Mount Dropout 277544 carbon-frame bike. It is not a specification upgrade over the other option; it is the weight-forward titled alternative.
Product notes
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black
Pick this hanger when the goal is to keep the listed cost as low as possible without moving away from the shared configuration. The title's "1pcs" wording is supported by the included one bike rear derailleur hanger, and the item is described as a black aluminum-alloy part at about 40g. For a shopper replacing the hanger on the named Scott #277544 Addict RC 2020 SC-R-SW1-S Standard Mount Dropout 277544 carbon-frame bike, those are the important identifying details. Its limitation is inherent to the one-piece format: the package contains one hanger rather than a multi-piece quantity. That is suitable for a single replacement need, but it does not add an extra hanger to the package.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
Choose this version if the "About 40g" wording in the product title is the identifier you want to match. Like its counterpart, it is described as a black, new aluminum-alloy bike rear derailleur hanger with one hanger included, and it uses the same Scott #277544 Addict RC 2020 SC-R-SW1-S Standard Mount Dropout 277544 carbon-frame bike application. The approximate weight is useful as a concise title-level reference for this replacement part. The limitation is that its stated material, color, part type, package quantity, weight, and bike application align with the 1pcs Black version. In this pair, the weight callout does not create a separate product specification advantage.
Final choice by use case
For a single replacement hanger where the shared Scott #277544 Addict RC 2020 application is the deciding fit description, choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black for the lower listed price. Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories only when its weight-forward title is the specific option you want to match. With the main listed specifications aligned, the lower-priced 1pcs Black hanger is the more direct choice.
