My coach wants me to start using a power meter when riding so that we can track my progress in the coming season in hopes that I can race more consistently. The two main options that I have found are PowerTap and SRM. There looks to be a pretty big price difference between these two….
While everything from fans to magnets are used to create resistance in cycling trainers for 2008, fluid or centrifugal force are much better methods. At around $300, these three units offer some of the smoothest and most progressive resistance available; regardless of price, they are the heart of the value equation in trainers for most…
How should a well fit cycling shoe feel? Not as many riders think. In many ways, a properly fit cycling shoe should fit much like a properly fit daily shoe. A well fit cycling shoe should be snug in the heel with even pressure on the instep. You should not be pressed against the end. …
What is Performance Analysis? Performance Analysis uses quantifiable computer data to improve your efficiency and speed through positioning. Your efficiency and speed on a bicycle is determined by four main variables: power, oxygen transfer, technique and aerodynamics. You don’t want to just maximize one at the expense of the others. Instead, you want to find…
Because I work with a large range of athletes, from pros and top age groupers to people buying their first road or tri bike, I thought a bit of perspective on positioning might be helpful as there is a lot of often contradictory information about proper positioning and fit technicians out there. Many industry triathlon…
As a solo rider, you do not have the benefit of being protected from the wind by a peloton of other riders as you would in a road race. When you are riding on your own, overcoming air resistance uses 65-70% of your energy. An aero position is designed to help you maximize your aerodynamic…
By Ian Buchanan Much of the bicycle industry has done a good job of creating the impression that different materials offer different ride characteristics. Aluminum is supposed to be stiff and light, but is also known for diminished durability and harsh ride quality; Titanium is supposed to be light, durable, comfortable and compliant, but a…
By Sarah Shorett, co-owner of Fit Werx Frame geometry differences can be a complicated subject. Hopefully this article can help make it a little simpler. Think about bike geometry as you would shoes. There are many different types of shoes and all have a distinct purpose. If you are going for a hike on trails,…
Frame Geometry and Handling – Energy and Power Use Breakdown* % of Total Power Consumption: Frame Geometry and Handling: Intangibile. The bottom line: A bike’s geometry and design combines with your position on it plays a large role in how comfortable you are on the bike, how stable the bike is, and how well it…
Mechanical, Compatibility & Friction – Energy and Power Use Breakdown* % of Total Power Consumption: Mechanics, Compatibility and Friction: 2%-100% of overall energy/power consumption The bottom line: Friction from an adequately maintained drive train, etc. can use up to 2% of your energy. Component incompatibility and mechanical issues are deal breakers. From flat tires and…
Weight of Bicycle – Energy and Power Use Breakdown* % of Total Power Consumption: Weight of Bicycle: ≈08% of overall energy/power consumption The bottom line: First, never forget that you the rider are 85-95% of the total vehicle’s weight – the bike and components are only 5-15%. Bicycle weight plays a comparatively small role in…
