A replacement rear derailleur hanger needs to match the bike application first; when two cycling accessories state the same fitment and nearly identical specifications, the decision should stay simple. Here, both options are black aluminum-alloy bike rear derailleur hangers described for Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout carbon-frame bikes. Their listed prices are close, so there is little reason to choose on broad feature claims alone.
Quick verdict
Choose Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy if the lower listed price is the deciding factor. At USD 19.60, it sits $1.41 below the other option while carrying the same stated material, color, approximate weight, part type, and Scott #277544 application.
Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories when its more explicit "About 40g" title wording is preferable and the USD 21.01 listed price suits your purchase. Its description states the same aluminum-alloy construction and bike application, so it is not a specification upgrade over the lower-priced hanger.

Where each hanger wins
Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy
The clearest win is price. The $1.41 spread is the only meaningful listed difference between these two hangers, since both use the same material, color, stated fitment language, and approximate weight. Shoppers replacing a hanger for the named Scott application can keep the decision focused on the lower figure rather than treating the two near-matching titles as different levels of equipment.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
This option wins only for shoppers who prefer its title to call out the approximate weight directly. "About 40g" is also stated in the other hanger's specifications, so the wording does not establish a weight advantage. Its higher listed price makes most sense when that presentation is the deciding preference rather than a need for a different material, color, or application.
Product notes
Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy
Pick this hanger for the most straightforward price-led choice: it is listed at USD 19.60, compared with USD 21.01 for the other option. The description identifies aluminum alloy, a black finish, an approximate 40g weight, and use as a bike rear derailleur hanger for Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout carbon-frame bikes. The package is stated to include one rear derailleur hanger, which suits a single replacement need. Its limitation is equally specific: the stated application is narrow, centered on the Scott #277544 Addict RC 2020 SC-R-SW1-S wording rather than a broad range of bikes.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
Choose the Cycling Outdoor Sports Rear Mech Hanger when you want a title that foregrounds the approximate 40g weight while retaining the same stated aluminum-alloy construction and Scott #277544 application. It is also listed as a new, black bike rear derailleur hanger and includes one hanger. The trade-off is the $1.41 higher listed price despite matching the other option on the core stated specifications. Another practical limitation is color preference: black is the listed color, so the decision suits a bike setup where that finish is the desired match.
Final choice by use case
For a Scott #277544 Addict RC 2020 SC-R-SW1-S replacement where the stated application matches your need, select Outdoor Sports Rear Mech Hanger Rear Hanger Accessories Aluminum Alloy for the lower listed price. Select Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories only if its weight-forward title wording is your preference. With the same stated black aluminum-alloy, about-40g hanger profile and one-piece package, the lower-priced option is the clearer default.
