DR4028: Right Side, Sliding, Hanger, Shimano 12 mm
A Paragon Machine Works drive-side slider plate with RD hanger. That gap of light between a flat pen-shaft and the inside face....that is what happens when someone knocks your bike over at camp
. That gap is also why my Di2 shifting was crap the morning of Day 3, luckily an index-adustment made the shifting "good enough" for the remainder of the tour.*
*Specifically ordered a spare slider plate (then left it in my car) in case this happened...
