What would be the benefits / trade-offs of swapping from Red and Force combo to Ultegra? Weight penalty but better shifting? Is Di2 worth the extra £400 or so? Also, if I have the correct press tool (big Park one), would installing the Praxis BB30 bottom bracket be that difficult? Looks pretty simple and hard to screw up from their instructional video on YouTube.
