Wilier Cento 10 SL rear derailleur hanger

To ensure smooth gear changes, it is essential to ride with a perfectly aligned derailleur hanger. To do this, you will need to replace it if your derailleur appears to be bent or out of alignment with the sprockets. The operation only takes 5 minutes and will solve the problem. It is advisable to then check that the hanger is correctly aligned using the tool designed for aligning derailleur hangers.

A derailleur hanger acts as a fuse in the event of a fall to prevent damage to the frame. It also ensures that the indexing is always perfect. Its condition is therefore essential.
