F.I.S.T. Axioms

This second in a series of articles describing our tri bike fit system lays out the axioms on which our F.I.S.T. system relies.

Measuring conventions

In this continuation of our series on tri bike fit, we tell you what we mean by terms like "seat angle" and "hip angle," that is, what landmarks we measure to, and why we choose them.

Proprietary rubber in today’s tri wetsuits

There are several companies that say they have rubber nobody else has. Let's take a look at those claims, and the rubber they're using, and see what we can glean about the state of materials in the wetsuits we use today.

Yet more wheel size debates

After two decades of heated declarations and ill-informed pronouncements, there remains not one shred of evidence suggesting one of these wheel sizes is inherently superior to the other. And yet...

Steering geometry for tri bikes

It's one thing to comprehend concepts like trail and steering axis and gyroscopic forces, another thing altogether to know with precision how a bicycle is going to handle once a design is executed in the form of a road-ready machine.

Stack & Reach Primer: Chapter Two

Our primer on stack & reach continues with the second chapter in the series. We examine how stack and reach enable you to understand how a given bike will, or will not, fit you.
