Which part does the power meter go in? (crank, spider, pedals, there used to be rear hub but I think they are out of production)
SteveB was right on the money with his Di2 wiring comments. SRAM is fully wireless with a battery on each component. Shimano 11 speed di2 was wired. 12 speed di2 is part-wireless. Does the power meter talk to your gps? Speed sensor too? Does the electronic shifting talk to your GPS?
If the braze-ons push you to a brand of shifter then that pushes you to a brand of GPS and power meter you choose. SRAM is all over this, making all of these products. For Shimano you get a broader range of choices that might be compatible longer because it's to their advantage but they can't achieve the same level of integration
