The Synco Signature series is the first Indian foray into the 21st century with their exclusive "chakri-less" design. The chakri, or back-bracing on the bottom of the playing surface, is meant to prevent the ply from warping over time. With the introduction of more stable materials, the need for this bracing was eliminated and a new design was born.The Synco Winit Signature is a much more stable version of their Winit with a 12mm BC Birch playing surface and a 3" x 1 3/4"" frame. Comes with Synco coins and striker (13-14 gms). 30 lbs
