I picked up some 12" wide by 22" tall Bearclaws for the winter/rocky trails.
Going wth 13/42 gearing to allow me to not have to clutch so often on the tright trails with the larger diameter tires.
Putting on heated grips and so have to save some Watts by using an LED tail bulb from Princess Auto and going to go with a single HID headlight later in the year.
