Hi - I know Venge is quite popular here so does anyone have any experience with this? Would I need to swap out the stock crankset and BB as well or is this compatible with a Di2 upgrade kit? Thanks
There’s no reason you couldn’t use the original crank and BB whether it’s the stock Praxis or SWorks crankset. If it’s the former, the Ultegra or Dura-Ace crankset might look nicer.
"While the demands for the chain and cassette are fairly stringent, chainrings (and cranksets) are far more forgiving, so it is possible to mix brands as well as 10- and 11-speed versions without having an impact on the quality of shifting.
Thus, cranks from Shimano, SRAM, and Campagnolo are freely interchangeable along with those from all aftermarket brands (e.g. FSA, Rotor, Praxis, etc.). And while it is preferable to match the chainrings/crankset to the transmission, there is no strict need to do so."
