Easy Installation
- Utilizes the dial mechanism familiar from shoes. Simply hook the elastic nylon wire and turn the dial for instant installation without tools.
High Securement
- The dial mechanism provides stronger and more secure fastening than conventional fasteners using rubber bands or tie-wraps, ensuring a secure fit and preventing slippage while riding. Use it with confidence, without worrying about the rubber deteriorating or breaking.
Multi-Shape Compatible
- Includes two types of rubber attachments, compatible with 27.2mm, 30.9mm, and 31.6mm round seat posts, as well as D-section and aerodynamic seat posts and seat tubes. One mount can be attached to a variety of bikes.
Scratch-Resistant Design
- Rubber is used on the contact points with the seatpost. Securely mounts to both carbon and aluminum seatposts without scratching their surfaces.
