Winmau - Callisto 02 - 90% Tungsten Darts

Callisto 02: the front-weighted barrel in Winmau's Callisto range

Winmau's Callisto range covers three tour-proven barrel profiles, and the 02 is the front-loaded one — a specialist shape with an elliptical nose that puts the mass ahead of your fingers for a committed, driving throw. At a consistent 7.8mm diameter across all three weights, it's noticeably fuller in the hand than the slim parallel Callisto 01 (6.28–6.6mm), so it suits players who like something substantial to hold onto.

Astro-Grip 90% tungsten barrel with atomised finish

The full-length Astro-Grip is Winmau's mid-level (3/5) texture, enhanced here by an atomised surface finish that adds fine friction without ever snagging on release. It's a grip that works across ability levels — enough purchase to repeat your hold precisely, smooth enough to stay consistent deep into a long session.

Vecta shafts and Prism Delta flights included

Each set is finished with silver-top Vecta shafts and Prism Delta flights straight out of the case — one of the cleanest-looking stock setups Winmau make. When your flights wear, we stock replacement Prism Delta No.2 flights. If you're wondering whether the Delta shape is right for your throw, our guide to dart flights breaks down how flight shape changes trajectory.
