At first glance the Draupnir and Sigtyr are pretty similar, but when you look closely you can see the key differences that sets the Sigtyr apart and really gives it a different feel on the string.
The Sigtyr is around 2 grams heavier and that weight is entirely focused in the rims. They made the steel rings broader, rounder, and if you look at the inner cup you’ll see just how much farther they protrude from the aluminum. This is where the Sigtyr really outshines the Draupnir – The incredible stability and spin power, not to mention a more comfortable feel in the hand!
The DS (Double Straight) Bearing is a double angled bearing designed to center the string. It was created to perform at a competition level and that is exactly what it does!
The DS Bearing has a more gradual angle than some other centering bearings out there so it gently centers the string during play instead of just forcing it which provides a much smoother feel on the string.
