Our latest research is looking at vibration and how it impacts cycling wheels, rolling resistance, and most recently, the cyclist.  What know that vibration in a human creates micro tears in the muscles and the body attempts to stabilize itself, both leading to fatigue.  Our theory states that if you can manage the vibration through…

I recently visited The Big Island of Hawaii and reviewed the bike course for Ironman Hawaii 70.3 and Ironman Kona. I’ve spent time studying the course and have been fortunate to attend the World Championship race seven times. Over the years I’ve learned a lot and hope this article will help prepare you for your…

Wider wheels = faster wheels. However, the key to getting the most out of a wider internal rim width wheel is accurate tire pressure. If you haven’t lowered your tire pressure, you’re losing time. This article walks you through why lower pressures are required for larger tires or wider rims. Casing Tension in Cycling Tires…

You probably know that wheels are an essential component of a bike’s design, but have you ever wondered how the spokes of the wheel work to keep it rolling? In this article, we’ll explore the highly debated question, “Does a Cycling Wheel Stand on the Bottom Spokes or Hang from the Top Spokes?” Does a…

Cycling wheels are one of the closest components to the surface of road and their design and materials can significantly impact the ride quality. (Note: a wheel does not include a tire.) One of the factors that affects the ride quality is the wheel’s ability to absorb vibration generated from the road surface. Carbon fiber…

On April 1, 2023, Ironman Oceanside kicks off. For many, this represents the start of a new triathlon season after a long winter. If you are participating in Ironman Oceanside you’re likely making your final preparations for the big day. This post is to help you prepare your ideal wheels, tires, and tire pressure to…

This is part two of the series Secret To Fast Cycling: How To Be An Efficient Cyclist. In part 1, we discussed cycling efficiency and mechanical systems. Today, we apply these concepts to aerodynamics.  Aerodynamics is important for you as a cyclist because regardless of how fast you are on the bike, understanding how to…

The goal for any cyclist is to use whatever you put into pedals to move you forward, efficiently. In my 10 years in this industry, it never fails that the fastest athletes find every mechanical advantage they can. This article is the introduction for how to be an efficient cyclist. Throughout this series we will…

The rule of 105 for a cycling wheel states the following: The Rule of 105 states that the rim must be at least 105% the width of the tire if you have any chance of re-capturing airflow from the tire and controlling it or smoothing it. This was originally coined by Josh Poertner, who spent…
