• Why? Because of the lack of front derailleur? Been cycling around all weekend and absolutely no problems yet.

    Yup!
    I thought you would know the story of David Millar and his lost Tour de France prologue...
    Lots of road pro's ride with a 3rd eye chain watcher despite the front derailleur
    Cyclocrossers use 2 chain guards on their single front chain wheel.
    It is just a tip.
    Think about it when your chain drops off.
