SRAM worked with the U.S. Consumer Product Safety Commission and other global authorities on a voluntary product recall of SRAM RED 10-speed medium cage rear derailleurs. SRAM has determined that there is a potential for the derailleur parallelogram to jam and no longer shift.
This presents a safety issue. As a result SRAM is actively retrieving and replacing all affected SRAM RED 10-speed medium rear derailleurs. SRAM has already begun a pro-active quarantine of product. SRAM advises consumers to stop using these products immediately. Failure of the SRAM RED 10-speed medium cage rear derailleurs while in use may result in loss of bicycle control and possible injury.
In the public recall announcement, we ask consumers owning one of these products to stop riding immediately and confirm the derailleur has a serial number between 31T2000000 ? 11T39999999, and return any affected derailleurs to their dealer to obtain a free replacement. Please refer to images to confirm serial number location.
Any dealer with a SRAM RED 10-speed medium rear derailleur installed on a bicycle as part of a groupset within the indicated serial number range can exchange these derailleurs with their local SRAM DSD, TechCenter or SRAM Distributor. Return of the existing derailleur would be required, replacements would be shipped with a SRAM 1091R.
