A couple of additions to those above. Most teams use 25 or 35 chain so finding links, clips and spares at a competition is easier if you stick to these "standard" parts. If you use chain, please make a design that allows you to compensate for wear/stretch as this will occur. More than a few teams learned this the hardway when their chain fell off in a finals match. And please never attempt to rethread a chain under motor power. Keep it safe out there.!
