Hi , i was going pretty hard last week , trying to maintain a constant speed of about 35km/h. I made the mistake of looking down and the next moment my front wheel hit a HUGE chunk of what seemed like clay. The front end of my bike flew up and my hands left the handlebars for a split sec. Luckily i did not crash but the impact was pretty big and the chunk of clay bounced off the curb and hit my front wheel. Amazingly my wheel is still true and i did not puncture , but now there is a small bump on my rim. I did not notice it till the day after when i pressed the front brake and there was a slight scratching sound. Would the bump be an issue? Can i try to sand it down? It is not causing any problems to me or my brake pad except for the slight sound.Thanks.
