The Seba Fr1 310 Inline Rollers in black are ideal for fast skating enthusiasts. Their design with aligned wheels in the center of the frame, beneath the boot, offers increased speed compared to Quad Rollers, as it reduces the surface area in contact with the ground. This feature makes them a perfect choice for those who want to enjoy speed and athletic challenge. Using them requires good balance and control, skills that experienced skaters develop through techniques for adjusting speed and stopping.
