Megamo fork with the 185mm alum rotor. The alum disc with Kool stop pads seems to provide quite a bit of power now. I guess time will tell how long the rotor or the pads are going to last. The wheelbase is 1080mm with this setup. The front end is the lowest I ever had on any stock bike but I seem to tap a lot more consistantly than with the previous setup that put the handlebars by about 2 inches higher.
