Compatibility and Ideal Use Cases

Designed for Chase frames with 27.2mm aero seat tubes, including ACT 1.2, RSP 5.0, RSP 4.0, RSP 3.0, and Element frames (Expert XL, Pro, Pro XXL+, and Pro Cruiser sizes). Must be used with Chase 27.2mm aero seat posts or Chase aero post extenders—standard round seat posts will not fit properly. Best suited for competitive racing on Chase platforms where quick seat height adjustments are needed between motos or when sharing bikes with different riders. Not compatible with standard round 27.2mm seat tubes or non-Chase aero profiles—verify frame compatibility before ordering.
