http://www.nsmb.com/5213-vid-shimano-drd-derailleur-standard Just saw this, not sure if it has already been discussed here. I'm a fan of Shimano products in general, however my first thought was 'they just solved a problem that they created themselves'. In their original shadow implementation they basically tried to lock out the existing pivot at the derailleur mount, and make a new one further back - problem was that it still moved every now and then, especially if it took a hit. This solution removes the existing pivot to solve that problem. This standard definitely won't benefit SRAM unless they change their design entirely to line up with Shimano's... however it does benefit Shimano, and looks like it will make it easier to get your wheel in and out. But is that really worth another new standard?
