Material: high tensile steel + quenching treatment
Speed: 8 speed

Gear ratio: 13-15-17-19-21-24-28-32T

 

Advantages: It belongs to the entry-level durable flywheel, the overall compatibility is very good, the material hardness is high, and the durability is good.

 

Note: If the freewheel chain is used in combination with the old and new, the chain may jump at the beginning. This is because the old parts are worn out during long-term use. When mixed with the new parts, the wear of the tooth shape makes it impossible to perfectly bite.

 

Generally, in such a situation, you only need to continue to run for tens of kilometers, and the problem will automatically disappear. If your chain has been used for more than 3,000 kilometers, it is recommended to replace the chain at the same time as you change the flywheel.
