To change the tension loosen one of the axle-nuts and move the wheel forward or backward slightly and snug it up again. Then, loosen the opposite axle-nut, adjust and tighten, making sure the wheel remains centered in the frame. Re-check tension. A chain tensioner can make the process easier.

For two-sprocket or single speed bikes, replace your chain as it reaches the 1 percent wear mark.
Can a bicycle chain stretch?

How tight should a bicycle chain be?
It should be tight enough that it only allows you to move it up and down about one inch. If it is sagging or much looser than that, you need to tighten that chain up. Chains often loosen when a bike does not have a derailleur. Derailleur is the gear changing mechanism towards the back of the bike.

When should I replace my Shimano chain?
To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same.
What is the best gear ratio for a single speed bike?
A gear ratio is determined by the number of teeth you have in the chain ring and the rear cog. We personally recommend riding a fixed gear or single speed bike with either 44 or 46 teeth in the chain ring (hence the first number in the gear ratio) and a rear cog with 16 teeth.
What causes a chain to stretch?
Another highly significant factor in chain stretch is the accumulation of dirt particles between parts of a chain. These particles form a paste with existing petrochemical lubricants, and they will cause pins, rollers, and bushings to lose material rapidly, again resulting in an overall elongation of the whole chain.

What are single speed bikes good for?

How much tension should be on a fixie chain?
Chain Tension There should be approximately one half inch of movement in the chain up and down at a point half way between the front and rear sprockets. To change the tension loosen one of the axle-nuts and move the wheel forward or backward slightly and snug it up again.
What’s the point of a single speed bike?
For those that ride a single speed with a freewheel, there are many advantages of going with one gear—price, weight, maintenance and ease of use. There is physically less to a single speed, less moving parts that require an initial outlay and ongoing maintenance, accounting for reduced cost and weight on the frame.
