To set your saddle correctly it needs to be securely in place. A loose seat post can slip when you're out and about on your bike. Conversely, if it's too tight, you run the risk of crushing the seat post and damaging your bike.The best way to tighten a seat post is to use a torque wrench. We recommend you tighten it to between 6 and 7 Nm.Take care not to exceed the maximum height indicated on the seat post.
