    Scalpel SI 2017: Converting from 1x --> 2x

    Hi,

    I own 2017 Scalpel Si with 1x11 and would like to go 2x11 with Di2 XT.
    The Di2 upgrade parts are the one I understand.

    I'm not sure what parts I need in order to go from the stock 1x spider to 2x setup.

    Please help..

    Thanks

    I did same thing. I found an AI spider on eBay and used FSA 26/36 chainrings. Works great. Chainline is dead on. Many people are doing the opposite so they are selling they are selling the spiders. You can see picture on last page of 2017 scalpel thread

    When you are ready can you please share some photos how did you route Di2 cables at chainstay.

    I'm considering the same but I'm hesitant how it would look like.

    I run mine under the chainstay in the area where the cable housing bosses are. I place simple electrical tape pieces in between the bosses. Looks clean and functions well.

    I'm a little bit confused with the exact spider that fits.
    I found this but not sure it's good (also quite expensive):

    Can you link one please?

    I went from 2x to 1x. I still have the take off chainrings. Maybe we can work out a deal

    KP352 is the correct part number.
