A few years ago I converted my XT Shadow + RD to be able to accommodate a WT 49T GC by replacing the stock cage with a Wolfcage kit. Over time, whenever I backpedal too far, or during high speed, bumpy descents, the chain would actually jump off the upper jockey wheel and lay stationary within the RD cage. The chain seems to fall inboard inside the RD cage, and does not jump off the single chainring I use (I have a chainguide too).
The chain is not stretched, but perhaps I should remove a link?
