- The GXC is the most aggressive of the range - Utilizing closer spaced arrow shaped blocks in the center rolling resistance is maximized despite a deeper tread depth. Arrow shaped blocks in the center encourage mud and water down the channels in the tread to keep tread mud free. Rearwards facing edges on arrow blocks aid grip under acceleration - The shoulder tread has been designed around maximum grip. A combination of spaced and specifically placed blocks and siping helps the GXC offer enormous grip levels that blur the lines with mountain bike tires - Tubeless ready - Features a dual compound and puncture protection
