One size does fit all. A full-length frame pump that securely locks into nearly any frame. The PMP-5 quickly adjusts (no tools needed) to fit small to large size frames so riders can use one pump for multiple bikes and retailers can stock just one frame pump. All aluminum barrel construction ensures long life and fluid operation. The PMP-5 is Presta and Schrader valve compatible and features a dual density, soft touch flip-out handle for smooth, comfortable pumping. One pump, multiple bikes, fast and easy!
