You can cycle freely on these streamlined rollers to refine your coordination and pedaling technique. The heavy-duty tapered rollers ensure that it is almost impossible to ride off the machine. High concentration on steering is required when riding without a brace; this reinforces your sense of balance. The Antares is collapsible and measures only 80 cm when collapsed, making it easy to carry. These tough rollers are also ideal for track riders who want to warm up just before their race.
