A rear mech hanger is a part where the bike-specific application matters far more than broad cycling-accessory labels. Here, both choices are described for the Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout, with nearly identical stated specifications. That leaves a simple decision: select the lower listed price for a like-for-like replacement, or choose the version whose title makes the approximate weight more prominent.
Quick verdict
Pick Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black if the lower listed price is your deciding factor. At USD 18.83, it is $0.48 below the other option while carrying the same stated black color, aluminum-alloy construction, approximate 40g weight, and rear-derailleur-hanger part type.
Choose Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories when the "About 40g" wording in the title is the detail you want highlighted. Its USD 19.31 price is higher, but the listed application and core configuration otherwise closely match the 1pcs version.

Where each option comes out ahead
When the "About 40g" wording is useful
The Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories title puts its approximate 40g weight directly in view. That can make it the more immediately readable choice for a shopper comparing similarly named hanger options and wanting the weight cue up front. This is a title-level preference rather than a stated mechanical distinction: both descriptions identify an approximate 40g weight, black color, aluminum alloy, and one rear derailleur hanger.
When listed price is decisive
The Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black has the clearer practical edge for a direct comparison because its listed price is $0.48 lower. Its "1pcs" title wording also aligns with the one-hanger package detail. Since the stated bike application, material, color, and part type match the other option, this is the more straightforward choice for someone replacing one hanger and prioritizing the lower displayed price.
Product notes
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger About 40g Accessories
This option makes sense for a rider focused on a rear derailleur hanger described for the Scott #277544 Addict RC 2020 SC-R-SW1-S standard-mount dropout and who likes seeing the approximate 40g weight called out in the product name. The stated aluminum-alloy construction and black finish keep it aligned with the other listing, while the package detail identifies one hanger. Its concrete limitation is the USD 19.31 listed price: it sits $0.48 above the 1pcs Black version without a stated difference in bike application, material, color, or included count. Choose it when the "About 40g" labeling is your preference, not because you need a different stated configuration.
Cycling Outdoor Sports Rear Mech Hanger Rear Hanger 1pcs Accessories Black
For a single-hanger replacement, this is the cleanest all-around pick in the pair. The title specifies "1pcs," and the package description likewise calls for one bike rear derailleur hanger. It is also described with the same black aluminum-alloy construction, approximate 40g weight, and Scott #277544 Addict RC 2020 SC-R-SW1-S application as the alternative. The limitation is equally clear: the one-piece wording frames it around one hanger, so it is aimed at a single replacement need rather than a multi-hanger quantity. With no stated specification advantage separating the two, its lower listed price is the meaningful reason to select it.
Final choice by use case
- Choose the 1pcs Black Rear Mech Hanger for a one-hanger replacement when the lower listed price is the deciding factor.
- Choose the About 40g Rear Mech Hanger if you prefer the title that foregrounds approximate weight and are comfortable with the higher listed price.
- Either option matches the same stated use when you need a black bike rear derailleur hanger for the named Scott #277544 Addict RC 2020 SC-R-SW1-S application.
