So far what I found for upgraded cages for the T-Type are the Ratio SR52T & Cascade Components Transmissions Derailleur cage. From what I've seen both seem to be a improvement over any of the stock cages. While the Cascade looks like it is the best of the two the price seem way out of whack even when considering that. Has anybody used either one of these with or without the new jockey wheels or better yet used both? What other options for upgraded cages have people tried?
