These are triple flanged hoops - with a twist. Instead of the top edge of the hoop turning outwards like standard hoops, S-Hoops turn inwards towards the drum head. This allegedly makes the hoop more rigid and creates the effect of a die cast hoop, but without the added stress. Features - 2.3mm Thick - Black finish - Greater tuning consistency - Smother rim-clicks - Easier on the hands - More vibrant sound Wake up your drums with a set of S-Hoops!
