Choosing a rear derailleur hanger comes down to matching the specific replacement-part reference while avoiding an unnecessary price jump between otherwise comparable entries. Here, both Cycling Outdoor Sports Rear Mech Hanger options present the same stated configuration, so the decision is unusually straightforward: focus on the listed price and the Scott #277544 Addict RC 2020 reference.
Quick verdict
The USD 20.85 Cycling Outdoor Sports Rear Mech Hanger is the stronger pick for most shoppers because its listed price is $0.16 lower. Both entries are described as black aluminum-alloy bike rear derailleur hangers weighing about 40g and designated for the Scott #277544 Addict RC 2020 SC-R-SW1-S Standard Mount Dropout 277544 carbon frame bike.
The USD 21.01 entry remains the same type of replacement part on the stated details, but it does not present a distinct configuration advantage to offset the higher listed price.

Where each product wins
Cycling Outdoor Sports Rear Mech Hanger - USD 20.85
This entry wins the price comparison. With the same stated part type, color, material, weight, and bike reference as the other option, the lower listed amount gives it the practical edge for a like-for-like replacement decision.
Cycling Outdoor Sports Rear Mech Hanger - USD 21.01
This entry carries the same stated replacement-part profile. It fits a shopper who is specifically selecting the USD 21.01 entry, but the descriptions do not identify a separate feature, finish, or compatibility distinction that sets it apart from the lower-priced option.
Product notes
Cycling Outdoor Sports Rear Mech Hanger - USD 20.85
At USD 20.85, this is the sensible choice when the Scott #277544 Addict RC 2020 SC-R-SW1-S reference aligns with the rear derailleur hanger being replaced and price settles the decision. Its stated use with the Standard Mount Dropout 277544 carbon frame bike gives the entry a clear, specific replacement-part focus rather than a broad cycling-accessory role. The package is described as containing one bike rear derailleur hanger, which suits a single-part replacement. Its limitation is equally specific: this is a black hanger intended around the named Scott reference, so it is best approached as a targeted component choice rather than a general-purpose bike accessory.
Cycling Outdoor Sports Rear Mech Hanger - USD 21.01
The USD 21.01 option is a matching alternative for shoppers selecting this particular entry and seeking the stated black, aluminum-alloy rear derailleur hanger configuration. It is also described at about 40g and tied to the same Scott #277544 Addict RC 2020 SC-R-SW1-S application, making its role clear for a focused replacement need. Choose it when that named bike reference is the priority and this is the entry you intend to use. The limitation is the $0.16 higher listed amount: the stated material, color, weight, part type, and compatibility reference do not provide a differentiator over the USD 20.85 version.
Final choice by use case
- Choose the lower-priced entry when the named Scott rear-hanger reference matches your replacement need and you want the more economical listed option.
- Choose the USD 21.01 entry only when you are committed to that specific entry; its stated configuration remains aligned with the lower-priced alternative.
For a direct head-to-head choice based on the listed details, the USD 20.85 Cycling Outdoor Sports Rear Mech Hanger is the better fit.
