Since 2006, this has been the gold standard in tech slide wheels.  We are not joking.  Nothing compares to slide-A's...Don't just listen to us, go google it, or ask someone who has been around for awhile. The predictable release, and hook up is signature.  The wear is perfectly even right down to the core.  We also introduced a new dual duro 58mm in the same amazing slide-A formula.  This is a perfect wheel for anything street.  These have superior abrasion resistance, and great feel.  Even though these are about 25% more expensive, you could get 40-50% more life from them.  They are a little taller and thinner than the OG slide-a's, and the core is wider than the contact area.  These will not deform and cone allowing long low friction slides.  Blunt's and spins will be icy, and quiet.
