Power meters are also less helpful for off-road disciplines like cyclocross and mountain biking. They can be great training tools, but if you ride on muddy, wet trails often and need to spray your ...
Crank arm based power meter. The small box on the rear of the left crank arm contains the strain gauges. A cycling power meter is a device on a bicycle that measures the power output of the rider. Most cycling power meters use strain gauges to measure torque applied, and when combined with angular velocity, calculate power. [1]
SRM cycling power meter. Schoberer Rad Meßtechnik (SRM), or Schoberer Rad Messtechnik, is a company which created the first cycling power meter.Formed in 1986 by Ulrich Schoberer in Jülich, North Rhine-Westphalia, Germany, the firm's name literally means "Schoberer’s bike measurement technology."
Tri bikes are generally very similar to time trial bicycles used in time trial races. In 1989, Empfield designed the Quintana Roo Superform, a triathlon specific bicycle "built from the aerobars back" which provided an aerodynamic advantage as well as more power when in the "aero" position. Empfield's bike had 650c wheels and an 80 degree seat ...

From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
A triathlon is an endurance multisport race consisting of swimming, cycling, and running over various distances. [1] Triathletes compete for fastest overall completion time, racing each segment sequentially with the time transitioning between the disciplines included.
An Ironman 70.3, also known as a Half Ironman, is one of a series of long-distance triathlon races organized by the World Triathlon Corporation (WTC). The "70.3" refers to the total distance in miles (113.0 km) covered in the race, consisting of a 1.2-mile (1.9 km) swim, a 56-mile (90 km) bike ride, and a 13.1-mile (21.1 km) run.
