I'm currently running 1x setup on my TT bike with a 52T ring up front and a 11-36T cassette in the rear. In most circumstances this is just fine, but to get a perfect gear range, I'd like to drop the front ring to 48T and use a 10-32T cassette. That would get me both a little more high and low gearing.

However, I'm not sure this can be done, as the SRAM XD-driver cassettes appear to be one piece construction (i.e. you can't take 10T cog from the 1180 and replace my current 11T cog).

Is there any way to make this work?

I've thought about simply running the 10-42T cassette, but ruled this out as I'd get far more high gearing than I'd need and as a result the jumps between cogs (on a % basis) would be greater than I would like for a TT bike.
