I have built my bike to be bombproof for my size 240lbs and 6'2". I mounted a set of Azonic Outlaws with 2.4" tires and found out quickly how I love the lower rolling resistance of a narrow (2.1"Crossmark) vs a wider tire. However, I basically only ride XC (harshly) and am concerned the Azonics may be too wide (32mm) for a 2.1" tire. Should I replace the Outlaws with something narrower to accomodate a skinnier tire better?
