The problem with most new builders is that without the experience of installing an engine and knowing what it takes to get everything aligned, they won't see the benefits of certain frame designs. Therefore we have to keep them in mind and offer alternatives to running without a tensioner if they end up with a bike without the clearance needed.
Maniac's idea is a good one but limited to those with fabrication and welding skills. All too often we see a newbie who will say he doesn't have any tools or experience and his tensioner just rolled into his spokes. "Now what do I do?"
That's where we come in to offer those alternatives, and be glad that we don't have 3 chains to watch over.
Awsome looking bike, by the way and yes, your paint matches quite well.
