A replacement rear mech hanger needs to match the bike application first, but when two cycling accessories describe the same fit and construction, the decision becomes simpler: choose the clearer match for your priorities without paying extra for a distinction that is not meaningful to you.
Quick verdict
Both options are black, new bike rear derailleur hangers described for the Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout and carbon-frame bike. Each is described as aluminum alloy and about 40g, with one hanger included. The practical separator is the $1.44 listed-price spread: Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories is the straightforward pick for shoppers focused on the lower listed price. Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black when its explicit "1pcs" and "Black" title wording is the presentation you prefer.

Where each rear mech hanger wins
Choose the 1pcs Accessories Black title when clear count wording matters
The Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black option puts "1pcs" directly in its title, alongside the black color. That makes it a sensible choice for a shopper who wants the title itself to state the single-piece format. Its description also aligns with the shared core details: an aluminum-alloy hanger, roughly 40g, for the specified Scott #277544 Addict RC 2020 application.
Its limitation is simple: it carries the higher listed price while describing the same black color, aluminum-alloy material, approximate weight, and bike application as the other hanger. If the explicit count wording does not affect your decision, that higher price does not correspond to a stated functional difference.
Choose the About 40g Accessories title for the lower listed price
The Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories option is the better fit for shoppers who want the lower listed price while retaining the same described rear-derailleur-hanger type, black finish, aluminum-alloy construction, and Scott #277544 Addict RC 2020 application. Its title also makes the approximate 40g weight the headline detail, which may suit shoppers comparing compact replacement parts.
The trade-off is that its title highlights weight rather than explicitly including "1pcs" and "Black" in the product name. The description still states one bike rear derailleur hanger and black color, but shoppers who prefer those details front and center may find the alternate title easier to scan.
Product notes
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black
Pick this hanger if you want a black replacement labeled directly as a one-piece accessory and your bike matches the Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout description. The title is especially direct about count and color, while the description identifies aluminum-alloy construction and an approximate 40g weight. That combination keeps the selection focused on a specific rear derailleur hanger application rather than a general cycling part.
The main limitation is comparison-based rather than technical: the competing hanger presents the same stated material, color, approximate weight, part type, and bike application at a lower listed price. This choice makes the most sense when the explicit "1pcs Accessories Black" wording is worth choosing over the lower-priced alternative.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
This is the logical first choice when your priority is paying the lower listed price for a black aluminum-alloy bike rear derailleur hanger described for the Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout. Its "About 40g" wording calls attention to the approximate weight, and the description identifies one hanger in the package. For a replacement decision centered on the shared Scott application, it covers the same core description as its head-to-head counterpart.
Its limitation is presentation: the product title does not spell out the one-piece count or black color as prominently as the other title. That does not change the shared description, but it may matter to shoppers who prefer the name itself to foreground those details.
Final choice by use case
Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories for the lower listed price and the same described Scott #277544 Addict RC 2020 application. Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black if a title that explicitly foregrounds the single-piece black format is your deciding preference. For most shoppers choosing strictly between these two closely matched cycling accessories, the lower-priced About 40g option is the cleaner call.
