- 125 mm wheels -
Speed Technical Committee
Considering the evolution and growth that our sport has attained in the last years, the FIRS and the Speed Technical Committee have decided to allow, starting from February 1 2016, the use of the wheels up to a maximum size of 125 mm but only for the Marathons (Junior and Senior) and the Master Category (Men and Ladies).
We will be grateful for the spread of this information and we take this opportunity to send you.
