Best Bike Chain Tension Idlers Buying Guide
Before choosing the best bike chain tension idlers you should consider following options:
1. Position of the idler:
The position of the idler is very important. If the idler is placed in front of the chain, the chain will be smooth and quiet. If the idler is placed behind the chain, the chain will be very noisy.
2. Position of the idler relative to the chain:
If the idler is placed in line with the chain, it can be a front or rear mounted idler. If the idler is offset from the chain, it is always a front mounted idler.
3. The number of links in the chain:
If the chain has only one idler, the links are connected in a series. If the chain has two idlers, the links are connected in parallel.
4. The material used for the idler:
The idler is always made of steel. The steel that is used can be steel that is easy to find in your country, or special steel that is available in specialty shops.
5. The thickness of the steel:
The thickness of the steel is very important. A thick idler will be very durable and will have a long service life. On the other hand, a thin idler will have a short service life, but it will be light and portable.
