"Here is the skinny on Kung Fu tubing. Kung Fu is a fully proprietary triple butted seamless steel tube set. Its actually stronger and yet far more affordable than the OX platinum tubes that we used to use. We are very excited about Kung Fu tubes and you will see them used on more of our products in the future. Why the name? Well...that is actually a funny story. When Pete Koski (the engineer here at Salsa that designed the tubes) first brought the design to the company the physically makes the tubing for us they were so impressed by the design that they told him he had "good engineering Kung Fu".

OX/853/KungFu, I doubt any of us could blindly pick which steel they were riding.
I agree with Ken, they are all awesome. But, one of my happiest days was when I bought this bike back from rlb.
that being said, the El Mar is a fantastic, versatile bike. Someone is going to be very happy with it. Plus, that orange is sick!
