I was thinking about this some more and what it says to me is that we should support competition. Shimano thinks we're a captive audience, while they meanwhile outsource lower end parts production to poorer SE Asian economies and additionally with less money spent on R&D. Only the high zoot stuff is still made in Japan.
This part for example looks pretty nice and performs a similar function with similar ratings to Shimano rear road derailers: http://www.microshift.com.tw/RD-R47S_rd.html available here: http://www.ebikestop.com/microshift_r10_long_cage_10_speed_rear_derailleur-RD0103.php Shimano upped some of their ratings on their derailers after SRAM came out with the Apex that was rated to handle 11-32 casettes. But the old ones (long cages) were rated similar to the Microshift above. And I don't know that I believe that Shimano actually changed anything to achieve the higher rating, IMO. They probably just figured that their ratings were conservative and they had some wiggle room. Grant has in the past given Microshift parts a chance and I appreciate him for it. I'm pretty sure if Riv had issues with derailers snapping in half, they would pull them off their site. That being said Riv has never sold Tiagra to my knowledge.
