I’m considering a Franken-cassette - Shimano 11sp r8000 Ultegra, to go with 52/36 mid-compact crankset.
my thoughts are to take a 12-25T cassette, and an 11-32T.
like the idea of single tooth increments from the 12 so 12-13-14-15-16 and was wondering if using a 17 but then going to 20-22-25-28-32 - would the 3-tooth strep between 17-20 be too big? - I note of course that 22-25-28 are also 3 tooth increments, with final 28-32 being 4T difference.

I could use the 18T instead which would be 16-18-20, but I have a feeling that 17T would come in handy for my riding/cadence/road-speed.
it’s for a road bike, variety of terrain, some quite lumpy hence the desire to go to 32T.

appreciate any thoughts.
thanks,
david
