Hammered on this B A D B O Y E for about 4 hours on Saturday. 34 miles through the woods. Everything was perfect, but at about mile 24 I started hearing some clicking and noticed my rear wheel wasn't dished correctly. "Oh well," I thought. "I'll fix that when I get home. Not like I can do it now!"
I finished the ride, loaded my bike up, drove home and hung the bike up. When I went out to the garage the next day to redish the wheel and problem shoot the clicking noise, I was extremely surprised to find what I found.
The two screws that hold on the derailleur hanger completely fell out! The entire derailleur hanger was just sitting there, held only by the thru axle and chain tension. I have no idea how I was able to ride 10 miles over some pretty rough terrain, but thankfully nothing else broke as a result. I bought some spare hangers with the frame and they came with screws, so I hit them with some Blue Locktite and put them back. Wheel was perfect and the clicking was gone, of course.
