Question Via Email: How to set up and confirm my bike computer / Power meter Wheel size?

This is common question for anyone keeping any sort of data on a computer ... except the new Garmin 800 that automatically sets up wheel size every time you ride !

Q = How to easily setup my wheel circumference and how can I make sure its as close as possible?

A= The following are two basic ways to quickly set up your cyclo computer, Powertap, Power Meter Wheel Circumference and then cross reference to make sure your in the right range.

A Rollout to confirm these numbers is always best. To do a rollout put a tape measure, that has a metric scale, on the floor and then place your bike/rear tire with valve beside the start of the Tape (ie. 0mm). Carefully roll the bike exactly parallel to the tape until the valve comes around again and then carefully assess the point that you have stopped at on the tape measure in millimeters (for most computers)

Remember to do this with properly inflated tires and for bonus points add some down pressure or the intended rider to the saddle to compress the tires (more relevant to MTB)

The Quick way is a well tested chart (ie. rolled out many times, many bikes-tires)
