Hi,

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

Thanks

Main lever support interchangeability between groupsets

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.

SJS Customer Service:

Hi there,

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

Thanks
