1.9" od Aluminum 6061 pipe (1.5 ips) The standard for big water. The lightweight recreational frames built from the 1 1/4" ips (1.66" od) pipe are featured on another page. Having nearly identical unit weights, the 1.5 in pipe exploits the R^4 advantage for a significantly larger moment of inertia. The 1.5 ips also has nearly 6" of circumference for high rotational inertia inside the fittings. This gives the builder a 27% stiffer frame that weighs the same for identical geometries.
