I own 2023 Trek Roscoe 8 https://www.trekbikes.com/us/en_US/bikes/mountain-bikes/trail-mountain-bikes/roscoe/roscoe-8/p/35117/ Its stem is listed as: Bontrager alloy, 31.8mm, Blendr compatible, 7 degree, 50mm length

I've got Duo Base W537090 - https://www.trekbikes.com/us/en_US/equipment/cycling-components/blendr-integration/pro-blendr/bontragerxxx/pro/elite-stem-blendr-duo-base/p/25909/

However it doesn't fit the stem. I searched Trek's site for the stem but couldn't find it. Also looked at the Blendr compatibility guide at https://retailerassetsprd.blob.core.windows.net/techassets/BT22_MISC_Blendr_Flowchart_SEP22.pdf?sv=2018-03-28&ss=bfqt&srt=sco&sp=r&se=2062-03-20T02:32:45Z&st=2019-03-19T18:32:45Z&spr=https&sig=UogJIteiFltPX66np2M0a3esSu1uZzABYHTFInUlT%2Fo%3D but couldn't find relevant info.

Which Blendr Duo Base is compatible with the stem of the 2023 Trek Roscoe 8?

After chatting with the Trek site chatbot it seems the Legacy Blendr mount is the one compatible with the Roscoe 8 2023 stem https://www.trekbikes.com/us/en_US/equipment/cycling-components/blendr-integration/comp-blendr/bontrager-comp-legacy-elite-stem-blendr-base/p/W540565/
