Encountered a baseball sized piece of concrete construction debris in the middle of the road this morning. Glancing blow to one of my rear 17 inch wheels. Thought I’d hit a land mine or something. Bent the lip of the rim in a little. Caught it by the spoke, which lessened it, I think. Didn’t even notice it at first. Went back and removed the debris from the road. From what I’ve seen online, the damage should be repairable without too much trouble. Going to call a place tomorrow. If need be I have two spare 15 inch wheels ready to go.
