I'm in the process of building a Karate Monkey for general use that may include some light duty on- and off-road touring. Becuase of the intended use, I think a 48T large ring would be prefferable over the standard 44T mountain ring. But, if you are familiar with the set-up of a KM (i.e. curved seat tube), you know that there are specific tire rub problems with certain front derailleur/bigger tire setups. Has anyone here attempted to put a 48T on a KM with any success? Any ideas would be appreciated.
