About
The GTR JS is Jonathan Sitanggang’s signature version of the GTR platform. The size and shape remain identical to the GTR Beta, but the side faces are redesigned: the periphery is thinned as the side rises from center, pulling mass toward the wings and reducing total weight by approximately 2 grams while maintaining long-spin capability. Sitanggang won the 2017 Indonesian National Championship and is known for his seamless blend of rhythm and original trick vocabulary. The JS’s lighter weight makes it slightly more responsive to direction changes.
