Well someone who isn’t a pro cyclist doesn’t care about pacetime rides. I commute. 11-28 is fine on 8 speed. If I am out of gear I shift or pedal faster or slower. Not a huge ask. My chains are also like $10 and don’t stretch for years.

Electronic shifting I see as a con. Di2 at least is not serviceable and reaches an end of life. I am not as familiar with sram but I assume its the same. Either way just yet another old thing (index shifting) served to you in a new way that needs yet another battery to charge and eventually replace. Shifting is plenty fast on a mechanical brifter.

I have no interest in hydraulics and bleeding brakes. Brake cables stay in spec basically forever if they are stainless steel for the most part. By the time you’ve fouled up a mechanical system you are talking years of neglect exposure to the elements type wear that would do a number to any other bike system all the same.

Wet no issue the rim calipers squeegie off the water in the first rotation. The real limit of the reaction here isn’t the braking system. It is the tires. Even cheap ancient rim brakes are sufficiently overpowered to lock up a bike wheel even on new tires in dry conditions. Let alone wet.

Imo a lot of this tech is marketing vs true innovations. I mean brifter designs that shear off the end of the shift cable just because of rider ocd wanting it under the wraps, come on. Just that one marketing driven change has lead to diminished shifting experience and more difficult servicing for the end user. And basically all newish paradigms over the last 10-15 years of road bikes fall into this where its a dual edged sword that really only benefits the people racing professionally who have a justification to demand each and every legal free watt from a system, while hurting you the consumer with more expensive bikes, components, more expensive and complicated service, more forced obsolescence and eliminating old oem patterns of spare parts. We really did peak at 10spd side exit mechanical imo. Although 8 speed is more reliable and stronger components with wider tolerance to derailleur adjustment.
