DropperGK Posted May 3, 2015 Share Please could somebody help? I am trying to change my 2013 Giant TCR advance with ISP, DI2 system from an external battery to an internal battery system, but I cannot get my hands on an internal battery to check if it will fit. Please could anybody who has a Shimano SM-BTR2 let me have the exact dimensions or anybody who has gone internal on a 2013 Giant TCR advanced with ISP, let me know what they did. Many thanks Link to comment Share on other sites More sharing options...
