Giant Defy 3 Drivetrain Upgrade
I have a 2015 Giant Defy 3 endurance road bike. I wore the drivetrain smooth out over the past year. It came with a Shimano Sora 9 speed drivetrain. Would like to upgrade everything on the bike to Shimano 105 5800 wide range compact drivetrain and am gonna build a custom wheel set. Does anyone know if there will be any issues converting to 11 speed and if so what are they? Appreciate any advice and help. I do all my own work at my house.
