Can I use this with shimano 105 r7000 left lever?

these levers aren't listed as being suitable for use with this product so it is doubtful that they would work.

Main lever support interchangeability between groupsets
23 Dec 2017
Hello, are the main lever supports Y-63X 80010 (Dura-ace, Ultegra, 105, Tiagra) and Y05U00100 (Sora) interchangeable?

They look pretty similar. The latter one did not have photo available, but the right hand version (43278) has the photo and it looks rather similar to the Dura-ace's one.
Hi there,

No they are not interchangeable, using is there easiest way to source the rebuild parts for Shimano products.
