I just had one of those "Oh S**t" moments...
I went for a ride yesterday and hit some unknown obstacle pretty hard (one of the guys I was riding with said it looked like a metal plate or bracket or something). We were going about 30 and it nearly ripped the handlebars out of my hand - I did lose my grip with my left hand. I hit the obstacle with both wheels (aw great). Stopped, let my heart rate drop from 400 back to normal... wheels seemed true, tires were inflated so we took off again.
About 5 min. later I had a loud flat in the rear and it appeared to be a delayed pinch flat if that made sense. Fixed that and finished the ride, the front again appeared OK.
Front went flat overnight and I was in the process of replacing the tube and noticed this: (the third one gives you the best relative view of the size of the damage. There is a similar little dimple on both sides of the rim)
I rode another 10 miles downhill on this thing with no issues but of course I'm not confident about repeating the experience.
How serious is that? Can it be easily repaired by me? Should I chuck the wheel and start fresh?
