Quick verdict
A rear mech hanger decision gets tricky when two names appear nearly interchangeable. In this matchup, both descriptions name the Scott #277544 Addict RC 2020 SC-R-SW1-S and dropout 277544 application, while the listed prices are separated by $2.02. The practical choice is straightforward: the Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black carries the lower listed price, while the Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories may be the clearer match when the "About 40g" wording is the identifier you are using.

Where each option wins
Choose the 1pcs Black version for the lower listed price
At USD 18.83, the 1pcs Black hanger is the lower-priced selection. Since the listed color, condition, part type, material, stated weight, package quantity, and named bike application align across both options, the price is the clearest practical separator for shoppers comparing the two side by side.
Choose the About 40g version for title-specific identification
The USD 20.85 option is the one whose title explicitly includes "About 40g." That wording does not establish a different stated weight from the 1pcs Black option, but it can make this version easier to distinguish when that phrase is central to how you are matching a rear mech hanger name.
Product notes
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
Choose this option when "About 40g" is the wording you want to see directly in the product title. It is described as a black aluminum-alloy bike rear derailleur hanger with an approximate 40g weight, giving the title and description a consistent focus. The package includes one hanger, and the description names the Scott #277544 Addict RC 2020 SC-R-SW1-S and dropout 277544 application. Its clear limitation in this head-to-head is its USD 20.85 listed price, which is $2.02 above the 1pcs Black version. Pick it for title-based identification rather than for a stated specification advantage.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black
The "1pcs Accessories Black" version is a sensible choice when that specific title wording is the clearest identifier for the rear hanger you want. Its title directly calls out the one-piece format and black color, while the description presents it as a new bike rear derailleur hanger. The package is for one hanger, so it suits a purchase centered on a single replacement component rather than a multi-piece quantity. Its limitation is that the title does not foreground the "About 40g" phrase used by the other option, even though both descriptions state an approximate 40g weight. This is chiefly the lower-listed-price choice, not a different configuration.
Final choice by use case
Choose the Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black if your priority is the lower listed price among two closely aligned options. Choose the Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories if the "About 40g" title phrase is more useful for distinguishing the hanger you are selecting. For a like-for-like decision based on the listed configuration, the 1pcs Black version is the more economical pick.
