But why no cooling fins version? You wanted to have something that is in stock?

No fins is because I cheaped out: 5660 equivalent with fins (5840L, apparently shorter rotor, but same weight and Power, so more copper?) is over 200 EUR currently. TP's changing their specs all the time, the one I ordered seems to be a previous version; maybe that's why it was cheaper. Too bad the table doesn't list Rm:
Bit of a gamble, but we'll see. It's no custom work, so if I get a different motor, I'll send it back.

Not a stupid question at all Ruud! Having a bigger pinion than spur just makes the gearing taller than 1:1, so with the center drive-shaft spinning even faster than the motor shaft. There's nothing 'magic' about 1:1 gearing, it just happens to work well with the typical 40 mm, high kv, motor set-up used by speedrunners. If motor RPM goes down though, you need taller gearing to achieve the same wheel-speed. Kershaw actually has some over the counter pinions up to 60T for use on lower kv 1/5th scale motors:
