I have asked the three main USA cart / chassis manufacturers if they are using USA made chromoly tubing and none of them give me an answer like it is some type of secret / propriety formula. Weird. I though they would be saying, yes USA made tubing. I used to make chromoly bmx bikes and would proudly say made in the USA with USA made / True Temper tubing. What do you guys think? Anybody know what kind of tubing Margay uses? Ger.
