Conclusion

There are a few things to consider when tensioning a single speed chain. First, the chain should be tight enough that it doesn’t fall off, but not so tight that it puts undue stress on the chainring or cog.

Second, the chain should be aligned so that it runs smoothly between the cog and ring. Third, the chain should be lubed so that it runs smoothly and doesn’t rust.

Assuming that the chain is the correct length and the ring and cog are properly aligned, the chain can be tensioned by first putting the chain around the ring and cog. Next, pull the chain tight and hold it in place with one hand.

With the other hand, use a chain tensioner tool to tighten the chain by turning the tensioner clockwise. The chain should be tight enough that there is no slack, but not so tight that it is difficult to turn the pedals.

Once the chain is tight, lock the tensioner in place so that it doesn’t loosen.
