Good Morning!

I am building an Alfine Di2 bike (same as putting together a 1x10 or 1x11 system), and I was wondering...

Can I use the SM-EW90 A Junction Box to connect everything? This way, I also wouldn't need the B Junction box.

Since the SM-EW90 A Junction Box has three ports, they would go;
1. To the rear derailleur (Alfine hub in my case)
2. To the shifter
3. To the battery

Yes you can as per Shimano's compatibility chart. You would just need long enough wires depending on where you mount the A junction box.
