Oslo

The Oslo is a distance driver rated 12/5/0/3. Zero turn at speed 12 with a 3 fade suggests an overstable power flight that resists turning over and closes with a strong left move for a right-hand backhand; it is not a disc for low-power arms or turnover lines.

Gram Discs, the Estonian brand whose site says its molds are named after European cities, inspired by the soul of Europe's iconic cities in its words, pitches the Oslo at headwinds and strong arms, its listing likening it to a Viking longship charging through the wind and calling it built for fearless shots. The listing's title prints the same figures carried here. PDGA approval came on 14 July 2025, in the five-mold batch that followed the brand's first four certifications by two weeks.

TryDiscs records a Premium Line run of the mold.
