Re: Is tensioning necessary for #35 chain?

We would like to use chains next year, but avoid all those problems. From what I have heard, #35 chain is not very stretchable, and correctly calculating the center-center distance is sufficient. However, a mentor is still worried about stretching and recommended we add a chain tensioning system, which would add complexity to the chassis. What are your thoughts on adjustable tensioning with #35 chain? Worth it or not?

Wait to see what others post on this topic, but I personally am a fan of tensioning. In a pinch, you don't need an entire tensioning system, you can use beefy Zip ties to tension a chain.
We personally have done this in competition for belts, I have seen other teams use a similar approach for chains. It is very effective, cheap, fast, and simple, and because of that, its a no-brainer to add to any drive system.
