They are for looks and protection. YES , replace them . I have many ,many in stock. I am in southern Wisconsin. Could not find your location. The vacuum seal is below the covers. I would be more concerned about the impact damage. It takes a lot of force to do that much damage. Contact your builder and let him know what the shipper did. You may have internal damage.

I of course let the builder know what happened during shipping, he is currently searching for 3 fresh caps and as of past two days has not found any yet. I also have looked myself with no luck until asking here on this forum. I am located at ZIP Code 26034. I would be interested in 3 new/unblemished caps if he isn’t able to make it right pretty soon. I removed the caps and the plastic caps underneath seem fine. Once I get the cap then I will start to put the bike back together. Thank you da prez for the reply and offering fresh caps….i jus may need them.
