Hey everybody, welcome to the single tracks podcast.

My name is Jeff, and today Aaron and I are going to be talking about mountain bike frames.

You know, the frame is easily the most visible part of any bike build, and a well-built

mountain bike frame can last for decades.

So today we're going to focus on the most common materials

used in mountain bike frames and we'll discuss some of the fabrication techniques and also talk

about the pros and cons of each type of mountain bike frame. So a lot of our materials discussion

will also apply to bike parts like handlebars and seatpost as well.

So hopefully it will be good information all the way around.

Let's kick this off by starting at the most classic of bike frame materials, steel.

So Aaron, what is the process for building a steel mountain bike frame?

Well, before we get started talking about that,

I just want to, as a disclaimer, say that neither Jeff nor I are bicycle manufacturers or materials experts. So if we get any of this wrong, you might not know. We're going to get most of it right.

Yeah, you're going to get like 80 to 90% of the way there and like knowing what you're looking at and what you're talking about.

But yes, we will make mistakes.

You just know some armchair engineer is going to send it email.

As you said, steel is probably the most classic material that we have

for any bike, but particularly mountain bikes. It was widely used back in the early 80s when

mountain bikes first came into mass production existence. Before that, they were using like old steel
