Easy Installation - Featured is the dial mechanism familiar from shoes. Simply hook the flexible nylon wire and turn the dial for instant installation without tools. High Fixation - The dial mechanism provides stronger fixation than conventional products using rubber bands or tie-wraps, ensuring a secure fit and preventing slippage while riding. You can use it with confidence, without worrying about the rubber deteriorating and breaking.

Compatible with Multiple Shapes - Two types of rubber attachments are included, making it compatible with round seatposts such as 27.2mm, 30.9mm, and 31.6mm, as well as D-section and aerodynamic seatposts and seat tubes. One mount can be attached to a variety of bikes.

Scratch-Resistant Design - The part that comes into contact with the seatpost is made of rubber. It can be securely attached to both carbon and aluminum seatposts without scratching the surface.
