Unless there is a defect, the shimano crank system will never wear out. It is not a consumable item, same as campy BB's. the only consumable on both the shimano BB and the campy BB are the cartridge bearings.
I never said that the old square taper system is bad, or that it needs to be fixed. There is a potential there to make the system better, thats all. an oversized BB can be made out of lighter materials, larger bearings can be used that will give increased durability, whatever. I don't think that the potential of the external bearing-type systems have been fully realized. I do have an external bearing system on my mountain bike. Nothing wrong with it, nothing great about it, except that the bearings seem to be better sealed against the elements. I only have about a year on the system so far, so not a lot of experience yet.
All I said was that I don't see the net advantage to elec shifting. if there is one, tell me what it is.
Contrary to what you may be thinking, I don't think that Shimano is the greatest thing since sliced bread. They have gone down the wrong path (in my opinion, again) on a number of things over the years. (Biopace, rapid rise, etc). I use Octalink BB's, but I think they are crap, as the bearings are too small and are prone to contamination. No choice though if you use an Ultegra crankset (came with the bike). I prefer Shimano's road levers, since they are more comfortable to me. Personal opinion, nothing more.
Edit: you aren't seriously saying that Syncro was a good system, are you? It might have been, had campy developed it as a complete system rather than just levers. But it was heavily dependent on having just the right freewheel at a time which cog spacing was uneven on most freewheels, paired with just the right derailleur. They were marketing the levers as being universally compatible, or something like that. Syncro II might have been a bit better, I never tried that one.
