Rows of 4 small low profile and siped knobs line the center portion flanked by larger more aggressive shoulder lugs on each side for improved corner traction. Through the new RSR dual layer compound and low profile siped tread design the Helldiver shines with a perfect balance of traction and rolling resistance. Excellent tire for hard pack down hill single track trails and gravity riding on well packed routes. AEC – Using the same 3-piece Aramid inserts as the AGC casing AEC omits the apex at the bead: for the same high level of puncture and cut resistance but without the added weight. RSR – Building on the impressive original the new RSR compound is a dual layer tread rubber with the soft RSR compound on top and the stiff SRC on bottom
