Just about to pick up a Giant TCR Advanced Pro 2017 and want to change the Shimano Crank to a Sram Red one.
The bottom bracket fitted at the moment is a Shimano BB-71 PF.
What BB do I require for the Sram one GXP type being used, from what I can see it looks like I have to buy a BB86 anyone know for sure?
