[owly]

I did a short to medium switch, however on a clutch 2.1 XO 10sp.

Found a Sram tech doc online showing how to break down the whole unit i.e. remove the cage etc. Bit of a head scratcher winding the assembly/plates back on correctly again, but figured it out eventually.

Some time later I replaced the inner plate (bent it a little, I think) with a carbon inner from J&L in China through ebay. Stupid weight-weenie stuff.

Originally my 1x setup short-cage handled the 36t cassette no probs.
Now that I'm on a 40/22 with [mainly] 12-28, I can't remember why I went to or needed? the mid. Perhaps a chain-wrap thing.
