Yes. There is a threaded nut on the opposite side of the lever that allows you to fine-tune the clamping force so the lever closes securely without requiring excessive effort.

It is suitable for light trail riding and commuting. However, if you are doing aggressive downhill or high-impact riding, a bolt-on clamp is often preferred to ensure the seatpost does not slip under heavy force.
