It would be nice to be able to change gears while pedaling hard uphill. Seems like you can’t have much tension to change gears.

  Having a 1x drivetrain in my Trek Xcaliber and living up a steep hill, when changing up gears I have to sit down, do a pedal stroke like just letting the weight of my leg press the pedal and switch gear at the same time to avoid that hard snap in the chain. A little inconvenience but it does the trick, it changes smoothly

  Tom Boonen (former race bicyclist) is ambassador/investor in a company that solves that problem. https://www.classified-cycling.cc/ https://www.classified-cycling.cc/

    Hmm - looks like it gets rid of the front derailleur with a very proprietary rear hub, but that solves only one shift - small chainring to big is sort of an issue under heavy load (big to small, not so much) (so nothing to do with the cassette. There was an American cyclist (which I shall not name) who had a high cadence style and would attack on the hills. Part of his attack was quickly going into the big ring. They accomplished this with a down tube shifter that was perfectly set to just flip them into the big ring (STI existed but suffered from shifting under a high load - as well as being somewhat heavy for a high climb bike), while they were already quickly dancing on the pedals on the small, so a high load was less of a problem. Quite clever, actually.

  I have an old di2 and it seemed to allow that.
