I recently had a fall where my front wheel went into someone's rear wheel.
When i got back home i found a small mark on the top tube of the frame where i think my bars collided with the top tube. There's no visible damage to my aluminum bars or the bar tape.
I'm not sure if the carbon is damaged as I've tapped the mark and it didn't make a different sound when compared to tapping other parts of the top tube. I'm not sure if i should be concerned.
Any advice would be much appreciated.
