The Matter G13 is arguably the most developed wheel in rollerblading. Created over 20 years ago the wheel has been refined to perform at the highest level for all road, track and marathon events. The G13 is better for good conditions and are thinner in shape compared to Matter CODE wheels. 

What is the F rating?
The F rating is Matter's own durometer measure (how hard or soft the wheel is).
