Alpina Tubeless supermoto wheels utilize a patented sealed spoke and nipple design to achieve tubelessness. Billet aluminum hubs designed for each bike. Light weight racing or street rated wheels for supermoto, in variety of colors.  AFETY Increases puncture resistance Tyre explosion is minimized Overheating damage, due to  friction between  inner tube and cover tyre, is eliminated Better manageability  Spoked wheels are indestructible and  able to cope with heavy impact stress without bending Cover rotation on the rim creates no danger of  valve being ripped out  SMOOTHNESS OF THE RIDE No dispersion of energy ?caused by inner tube cover tyre friction  WEIGHT/RIDER HANDINESS The absence of the tubes, allows a loss of weight of about 1,5 Kg for each  wheel set The rotating bulk is reduced due to the elimination of peripheral wheel bulk. This optimizes the acceleration and both the rider handiness and the brake system   USE The tyre potential power is highlighted by the absence of rigidity in the tube, and the heat locally generated by the friction between the tube and the cover tyre Low pressure, very much appreciated in cross-country races optimizes the grip, therefore improving the managability of the cover tyre positioned between the rim and the outer tyre The shape then adjusts according to the road conditions, without added precautions The tyre is completely sealed, allowing no water or dirt to get in  MAINTENANCE The wheel doesn?t require any particular maintenance, except the usual balance wheel register and tyre substitution There are no longer any easily damageable parts The mounting and  removal of the tyre
