>>1307725which bike are you talking about?
your frameset will be the issue, not the calipers, it'll prob fit though
take those green vittoria's underbiking and larp as a paris roubaix rider lol
they're actually pretty damn good on gravel
maybe take a spare tire with you incase you nick a sidewall
iunno why you've got your bottle cages in the doofus CX position. Move them so they're easier to reach riding.
Also that blue bike, with the US postal colours, should have blue tape
