Replying here to the above.
I think Moments could be easier as from what I can see the Q factor seems less and the angle is more in a line rather than with the swoop of the Spirits.
I think this could mean that accidental downshifts are more likely with Moments and that Spirits are where they (Kris and Florian) worked to make a crank that was good for shifting - when you want it, but not when you don’t.
My ability to shift up is probably less than yours from what you’ve said - as I can be an over-thinker and have some mental blocks creep in. But yesterday’s shift was very nice because it felt effortless - and so while I think it can be tricky to get the positioning right and be able to click the button, when you do get those things right - the button should move with ease and pretty simple just change gear.
I know that 95% of the difficult I experience is self imposed - as in all the timidity and worry blocking the simplicity of the action itself.
I’m sure you know that some favour a heel shift or an ankle shift. (Clicking sharply with heel, or side sliding / pressing via the ankle).
I think I’m using a mixture, but it did dawn on me that for it to work and not be impactful to my left to right balance, I need the action to take place while peddling and be more of a contraction inwards rather than thinking “twist” / “heel kick”. If I think about those approaches I find it can mess with my balance control.
You are a pizza slicer, cutting cleaning forwards and precisely - a tough olive or piece of sweetcorn isn’t going to bother you as you’re focused… shifting is like pressing down harder to cut the pizza, nothing more.
If you’re able to feel the button passing your shoe or ankle as you pedal round, and then kind of go: 1, 2, Three-Press! - that’s how my shift yesterday went. It was part of pedalling and nothing more.
