Yep on the cassette buildup.
Used Sheldons gain chart to come up with something narrow spaced at either end of the spectrum as I'm using Velo Oranges Grand Cru 55.4bcd 46/30
going with the 12-14-16-18 up to 21-23-25-28
Having gotten used to the one step increments with the CFs 10 cog setup I guess I got spoiled.
Those giant leaps when you're climbing truly suck.
The lower end will work fine with the 46t
The upper end with the 30t chain ring should make life (on the climbs) easier.
If I need to I can swap out the 25 for a 26 and the 28 for the 30 (not as crisp but...)
