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. In addition to the extremely high performance, the Ricochethane urethane on the ROOL wheels provides excellent durability and vibration attenuation for many fast and smooth roles. The Ø75mm x 57mm wheels are slightly narrower and have smoothly rounded outer lips, helping to take slides at lower speeds, but still maintaining a great grip. They are indicated as front wheels for LDP / Push / Pump modes.
