Product Overview
The Magic Sprocket.
This sprocket allows the use of two runs of #25 series chain inside 2x1 box tubing for a perfect fit, prohibiting the chain from skipping off. Build your own chain-in-tube drive with your favorite wheels and the help of this magic sprocket.
This product was originally pioneered by Anthony Lapp from 221 Robotic Systems. Additionally, special thanks to Ty Tremblay and Team 319 for their insight and design advice on this product. This product builds upon this popular idea by adding chamfers to the teeth of the sprocket, as well as bosses on the faces to prevent the sprocket from rubbing the outer races of adjacent bearings.

Do you need an odd number of chain links? Tired of dealing with cotter pins in old school "half links"? Love using the DarkSoul or ARC chain tool for everything? These are the links for you!
These links add one and a half links to a run of chain making for easier cleaner alternative to half links. Use a chain splicing tool or two master links to install them. No more lost matches from a failed half link!
