Rool GLIDE are fast wheels!!! They were developed with the objective of high performance in speed, rebound and grip in balance with quality slides and with a lot of control. Also, in addition to very high performance, the Ricochethane urethane of the ROOL wheels provides optimum durability and vibration attenuation for many fast and smooth roles. The Ø74mm x 63mm wheels have a ventilated hub. This makes the wheel roll-speed with large wheels, but maintaining reduced weight, resulting in more agile and “smart” wheels. They have square lip and centerset position for greater grip, being indicated for Downhill Speed and as rear wheels for LDP/ Push / Pump modalities.
