Re: Chain Tensioners
You can run springed, but each bike is going to have a different alignment, which is the other purpose of the tensioner. You lose some of that aspect when you go springed.
I saw a simple springed not too long ago - simple enough, just added the tensioner on a lever bar attached to the stock tensioner with a carriage bolt, and the other side of the lever was p-taped to the chainstay and held to the lever via a spring. Looks like 5 bucks in materials and less than 10 minutes of work.
