But dropped chains and balky shifting are things of the past for the most part because the rings are better made.
As for the problem of ring wobble, do you really think that a little wobble of a chainring is going to have much influence on where a flexible chain is in the rear? We're talking about a chain that will deflect a large percentage of an inch from front to back if you are cross-chaining and a very small amount of wobble in a chainring (fractions of a millimeter) if there is any. If the chain were a rigid structure chainwheel wobble might be a problem but the chain is far from rigid.
Take a chill pill cyccocommute. You think you know it all, but unfortunately you don't. You seemed to downplay my 2x10 system and yet you had never toured on one nor accept that others who have it found it adequately. Personally, I'm not sure why are you so angry and dismissive of old cranks. It is a reference to what was then better accountability in the industry and where makers are proud to showcase their quality products. Sort of like full service airlines. These days, everything is on a per-charge basis with discount airlines. It's a reflection on today's economic reality. I'm not saying you have to spend $400 to $500 on a set of Rene Herse or T.A if you can find one, I'm just illustrating what happens if you have a set of good cranks. I also had a set of Shimano XT and Turbine Cranks and while they are good, they are not as true chain ring wise compared to my Sugino cranks. I measured. Am I anal about being a bit wobbly? Nope.
Keep in mind that Jan Heine charges $85 per chain ring on the larger sizes and $55 on the smaller sizes, which are more pricier than what Vuelta USA would charge you for the same chain ring size. Anyone can decide what is important. There is no right nor wrong. You always try to make it like that in any discussion.
Cheers..
