Our G13 wheel is the fastest road and marathon wheel in the history of inline skating. The 125mm version has had a big upgrade for 2018 with the introduction of the CHR core which allows for a more forgiving and faster ride!
As with all Matter wheels, F0 is designed for maximum rolling performance, while F2 is designed for maximum grip. F1 finds the happy middle between these two.
125mm : F0 / F1 / F2...
110mm : F0 / F1 / F2
