What type of terrain do you ride?
IF mostly flat, get a different cassette to replace the 11-32 you currently have.
Something like a 12-23/25 will give you closer spaced gears.
That allows you to maintain your cadence in a narrower, more efficient range.
11-12-14-16-18-21-26-32 vs
12-13-14-15-17-19-21-23 or
12-13-15-17-19-21-23-25
IF you don't spin out on a 48-12, you might even go 13-23/26
