• What bike is it going on/what ⌀ rotor is it designed for?
    You'll probably need an adaptor to make it work with 160mm, or else just buy the right sized rotor

  • I have 140mm rotors on the bike already, it's a genesis croix de fer. Is the brake mechanism the same? Does it just mean I'm buying a different sized rotor?

  • Yes, just different sized rotor. Some places stock the spyre with 140 rotors too, but none very cheaply

  • Are you're current brakes using is to post adapters?

    If so, chances are you could buy the Spyres and use with your 140mm adapters and rotors no?
