<yawn> Still just integer steps between gears, like everybody else.

Let me know when they develop cogs with non-integer numbers of teeth.
Only then will the ratios be close enough. Sometimes you really want
that 11.5 tooth cog!

Actually, 1/12 microstepping guarantees smoother shift starts than integer
steps, but works more crispier, less sluggish than a slacker NuVinci!

Here is the exclusive LEAKED preview of next season's (they'll skip the
dreaded #13) new Campagnolo Racing Record gruppo gear indicator:

Good point. I've known about NuVinci for quite a while.

Based on the operating principle, it seems to me the NuVinci would be
draggy, and online comments hint that it is. This site
https://www.cyclingabout.com/speed-difference-testing-gearbox-systems/
claims only 83.5% efficiency (although I don't see the NuVinci curve in
their graph). 83.5% is really low.

Has anyone here ridden one?
