Remembering Sheldon

“The bicycle on the cover was produced on the Management Graphics Table Top Slidemaking System at Crimson Camera Technical Sales in Boston.  A bicycle enthusiast created the image using the tablet menu and cursor tracker.  The bicycle is made up of 99 vectors, 20 circles, and 5 ellipses.  This simple graphic was created to illustrate to customers what 4000-line resolution looks like.”

The “bicycle enthusiast” was Sheldon Brown who worked for a short time at Crimson Camera.  Sheldon died eight years ago today.

The article on special spoking patterns for use with extra-large hubs (for example, electric bicycle hub motors) has been improved with patterns which avoid twisting the hub shell for two of the hub and rim combinations. The article includes all the information needed to use Damon Rinard’s Spocalc (also on the site) to calculate spoke lengths for these patterns.
