Here are the Jonescounter.com staff, experiencing inspiration from ancient culture. Tom, on left, is the designer and fabricator, who lives and works as a Civil Engineer in Virginia. Pete, on right, is the shipping clerk and webmaster, who lives in Ohio and is a retired Mechanical Engineer. Stock is shipped from Virginia to Ohio when Tom makes a visit. Both Tom and Pete are experienced course measurers.
The first counter, produced in March, 2008 is shown above. Note that the numbers can be read from left to right for easy reading, unlike previous models which had the numbers rotated 90 degrees.
The counter was modified in December 2014 (see below) to make the large gear stronger, and to fasten all the pieces of the chassis together using a swaging process. This eliminated the former brass grommet.
Above is the current Jones Counter
The counter consists of a gear assembly, fashioned of galvanized and stainless steel, to which a counter is attached. A delrin gear is attached to the counter shaft. The counter records the revolutions made as the wheel rotates. It is fastened to the front wheel of the bicycle, on the left side, and may be read by the rider while riding.
Details of course measurement may be obtained on the "References" page. Also on this page you can find a link to a measurement video.
To order the counter, refer to the “How to Order” tab at the top of this page.

Tough test of the counter. Although the JR shown is no longer in production the construction is identical to the standard JR. See the video below.
