Dummy bottom bracket

Dummy bottom bracket

thingiverse

I built this dummy bottom bracket to test fit everything on my new bike build without installing the PressFit BB72-41 bottom bracket first. The bike features internal cable and brake hose routing, along with an internal Di2 battery in the downtube, so I want to ensure everything works before installing the bottom bracket properly. Since there's enough overlap between the cups and the center piece, this dummy setup will also work for MTBs with Shimano PressFit bottom brackets.
