Hey man, thanks very much for posting this!
I just got a used Krampus, it was a custom build set up as 2x10, and I am going to convert it back to 1x10 the way god intended.
I plan to keep using the RD, which is the exact same as the one you've got, and going from 22/36 up front to just 28T, I'm not going to make it up the hills around here with 11-36 so I need a wider cassette. I see you've got the 11-42 on there, which is exactly what I want to use.
Any problems with reaching that 42? Do you still have the shadow mounted just on the frame, or did you need an extra hanger to get some more space?
