[15418] Double Aluminum Rollers with Rubber Rings (13-12 mm)

● The upper roller of the two-stage aluminum roller (13-12 mm), which is often used in races, has been made 12 mm with the rubber ring attached.

● The lower 13 mm roller normally comes into contact with the fence, and when the machine leans around a corner, the upper 12 mm roller comes into contact with the fence.

Not only does it act as a stabilizer to prevent falls, but the rubber ring also creates a braking effect to further improve driving stability.
