That Ceramic Speed, surely you're stuck with straight block "cassettes"? Number of teeth is proportional to radius (2 π r) and (I assume) the cogs have to be evenly spaced, which means linear increase in teeth. Thus the only options are 11-12-13-...-23, 11-13-15-...-35, 11-14-17-...-47 assuming that you start at 11. Which either means big jumps in top gears or poor climbing options with just one chainring.
On the other hand you could easily have a "triple" or more on the front for very minimal weight gain - even set of 13 cogs if you just replicate the cassette and have shifting mechanisms at both ends. No cross-chaining ever. Increasing from 13 to 15 speeds (at the back) would simply be a matter of replacing the "cassette" as long as the shifter bit can move far enough up the shaft, because the cassette expands radially outwards, not width-ways (necessitating more space on the freehub), so you'd never have to replace a wheel to upgrade your gearing.
You could have 11-23 at the back and something like 23-33-43-53 at the front, with all combinations usable for 52 speed. Now that would be amazing.
Alternatively you could go old-school and have a 11-35 cassette and closely-spaced/half-step chainrings (e.g. 47 + 50) for a fairly decent road range.
Now I'm excited about it. Make me a #cheapskate version with like 5×10 speeds and 700% range and I'm sold - I'd never buy another groupset again, in fact
Edit: no one else find this interesting?!
