Wilier Cento 10 Air derailleur hanger

To ensure and maintain smooth gear shifting, it is essential to have a perfectly aligned frame dropout. To do this, you will need to make an adjustment if your derailleur is not aligned. The operation only takes 5 minutes and will solve the problem. It is advisable to then check that the dropout is correctly aligned using the dedicated derailleur dropout alignment tool.

A derailleur dropout 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.
