I am not looking at a Marstrom extrusion, I am just looking for an extrusion with a 1/16" wall. It's very hard to find a stock extrusion even close to Marstroms. There is just not much of a demand for al, where you are weight sensitive. Most people are going to carbon so they only sell the thicker wall al extrusions. There are plenty of places that make al tubing (Easton, Reynolds, etc) but it is mostly on order and per spec.

This search was interesting to me, because I found I can buy hydroformed al tubing whose strength approaches cold forged al. I am not sure what I will do with this information, but it’s cool.
