This is a rotary aluminum spring retainer with a 1mm drop. It maximizes the spring's original performance by releasing the rotational force generated when the spring expands and contracts. This ensures effective input and output to the spring, leading to improved cornering performance and increased traction. It is compatible with springs with an inner diameter of 14.0mm to 14.5mm, and damper ends with a base outer diameter of 7.0mm or less.
