I've found that this only works for chain runs with a center-to-center (CTC) distance of less than about six or so inches for 25-pitch chain. If using 25-pitch roller chain with CTC distances of greater than about six inches, chain stretch becomes large enough that it can cause performance issues without a chain tensioner.
