Experience why the combination of bikes, mud and cowbells creates such a committed following on Cannondale's CAADX Disc 105! Its CAADX aluminum frame offers incredible efficiency while the SAVE stays and carbon fork keep the weight down and smooth vibrations whether you're tearing through the woods or sprinting out on the tarmac. FSA Gossamer cranks with 'cross-specific 46/36-tooth chainrings power a 20-speed 105 group that provides smooth, precise shifting even in nasty conditions. And speaking of mud, the Promax mechanical disc brakes offer plenty of all-weather stopping power and mud clearance while the Schwalbe cross tires hook up in a wide variety of conditions.
