I'm thinking mechanical.
And one reason I went with Dt240 hubs on the BTLOS wheels I have here for the incoming Strong is that DT seems to be amongst the best in designing their hubs to not go obsolete. So maybe my new wheels will go microspline if needs be? Quote:

Looks pretty cool to me. I like how slim the mechs are. Rear looks pretty cool,imo
The crank/chainring setup looks like the common CX setup where they use aftermarket rings and plastic finisher caps on the spider. I'm sure Shimano will have a hollowtech type of ring like the current DA. Only thing that I don't like is how tall the hoods are but maybe with a battery and hydro resi, it's just the limitations of space. Hopefully there is a rim brake version with normal Shimano size hoods.... Quote:

I'm betting the crank design to a (what looks to be at least) symmetric design was to remedy the power meter instability problems. Doesn't look the greatest in the spy shots but maybe DS arms will measure more accurately on this.

Longer version - it’s pointless moaning about the upgrade issues as you won’t see this group (or it’s lower tier derivatives) on anything but OEM spec for several years, unless you’re really really luck. Hell, I bet Mike Sinyard has already filled all available orders through 2023.

This will certainly be the case. Any bugs should be worked out by the time it is available through our LBS.

I got spanked when I posted that last bit of info about the DA 12. That's why that thread got removed.

I just watched this. Don’t know about sweeping changes yet to anything but |

The reason may be that controlled flex of the ring at the outer periphery might reduce cross-chain friction by allowing the teeth to lean a bit, better allowing the chain to flow into mesh with the chain under heavy side-loading conditions. Actually I've been waiting for single-ring bikes to adopt chainrings with relatively massive amounts of lateral flex in order to reduce cross-chaining friction. I experienced this effect on old three-arm cranks where the big ring did flex quite considerably while cross-chained, and noticed that the cross-chained chain's rumble seemed muted under heavier loading. I've mentioned here (and elsewhere) before how I thought that cross-chaining friction is something that will be seriously addressed in the future on racing bikes, perhaps with multiple chainrings being electronically shifted (specifically to reduce friction).

My old TA Cyclotouriste large ring certainly had lateral flex

*This is the only reason I can think of that Shimano attempted to foist reverse action rear derailleurs on the public, not once by twice (one called "Rapid-Rise", and another called "low normal"). Reverse action derailleurs produce very smooth shifts even with poor user technique, but can be balky under high torque, and more quickly suffer degraded performance on dirty drivertrains - in other words, their best use is inexperienced riders on short test rides.
