This stuff is quiet...
The gearing spread using XDR makes for smaller stiffer rings and the front shifting is bang on... or it isnt. there's no bang. It's VERY quick but it's smooth enough that it's without any sort of fuss. No chain slap...
Etap was already the easiest to install by miles.
Thank Fairwheel Bikes for sequential and corrected shifting... They were doing this for years with Hacking DI2... Including my Bedford Project...

Campy's 12 is also very good ratios, smooth, tight and quiet, large jockey wheels, and their disc brakes are fantastic.
