Tightening a Bike Chain on a Single-Gear Bike

2020-06-17

Single-gear bikes have the simplest construction where the cycle consists of a single gear in the middle of the frame and a cog installed on the rear wheel. As there is no mechanism to change the gears, this type of bike is referred to as a fixed-gear bike or a fixie.

Fixie bikes are oriented towards users who want to involve in a high-intensity workout as the single gear mechanism requires a fixed level of effort. Such bikes also have the easiest method to tighten a loose bike chain. To fix the chain on a fixie, here is what you will need:

-Gloves to keep your hands free from the dirt and grease
-A rag to wipe off excess grease and clean the dirt
-Lubricant for chain, gear, and cog
-A stand to position the bike upside down
-A socket wrench

-Once you have the necessary tools, proceed with the following steps to tighten a loose chain on a fixed-gear bike.

1. Orient the Bike Correctly
Flip your bike upside down so that it is resting on its saddle and handlebars. The wheels should be up in the air, as this is an essential part of tightening the bike chain on a single-gear bike.

2. Loosen the Rear Tire
Carefully loosen the axle nuts that are holding your rear tire onto the bike. This will loosen the rear tire, allowing you to adjust the tension on your chain.

3. Pull Back on the Rear Tire
By pulling back on the rear tire, you will increase the tension in your bike chain. You do not have to pull back a great deal, as you may cause your chain to break. Perform this process very slowly, as you can always check your chain to assess its tension.

4. Identify the Correct Tension
A good way of identifying the correct chain tension is to see if you are able to move it around half an inch in either direction. If you can move it more, push back a bit more on the rear tire.

5. Tighten the Rear Tire
When your ideal chain tension is established, simply tighten the axle nuts one by one, ensuring your rear tire is properly fitted onto the bike frame. While you are tightening the nuts, always look out for the rear tire position. You do not want your rear tire to make contact with your chain or the bike frame.

6. Check Operations
With the process complete, it is time for the last check. Assess your chain again, ensuring you can only move it about half an inch in either direction. Spin the rear tire, ensuring that it does not have the chain or bike frame in its way.
