Has anyone ever tried "pre-stretching" chain as an alternative to dynamic tensioning? If so, how much tension and time is needed to get on that plateau?
We've used previously used chain before with no problem. The working life of chain is much longer than a single FRC season. However, after a season, the chain is basically as long as it's going to get.
